Black Screen Asus Laptop What To Do
7 proven reasons why your laptop won’t turn on
In the mobile age, few people still use desktop computers. they are increasingly replacing them with laptops hp pavilion / compaq / probook, asus, acer aspire, Lenovo yoga, Samsung, dell inspiron, msi, good, sony vaio, packard bell, dns, emachines. irbis, prestigio, fujitsu, Digma, haier, iru, acker, xiaomi, fan, haier, 4good light am500, siemens, hi, alienware, brother, dexp, nek and others.
These are extremely useful devices, but they may also sometimes NOT turn on. What to do if the laptop does not turn on. just the black screen is on and that’s it?
The situation when the laptop does not turn on at all is NOT at all uncommon. I have seen such a defect in ASUS d541n, k750j, x551m, m50s, k52d, f3, f5r, x751m k50af x52n, k52n, n550, lenovo g500, g50, g505, g700, g580, b570e, g565 в590, np350, samsung r540e laptops r425, r528, np300e5c, rv508, np350, hp pavilion g6, m6, dv6, g62, dv7, g62, g7, 625, g7 2300er, 6715, probook 4730s, omen, bcm943142y, compaq cq58, presario cqire e15, acer 571g, v3 571g, e531g, v5we2, toshiba l40w, satellite l300, emachines e642g, d620, dell inspiron 15 vostro 15 3558, haier hi133, MSI vr330x, cx620, alienware m17x, iru jet people am 1521, sony, sve11501b11. dexp athena t132.
Only you should know that there can be many reasons that the laptop does not turn on. some of them are trivial and easy to fix, others are related to the graphics card and even replacing the motherboard.
Therefore, in my guide on what to do if the laptop does not turn on. only a black screen, I have collected the most common causes and solutions.
Reasons why the laptop does not turn on
Shocks, falls, moisture penetration can seriously damage the parts, as a result, after such manipulations, the laptop does not turn on.
There is one more basic problem. a broken power button, fix it to continue using it. Due to the broken power connector, you will also not be able to use the device.
Laptop won’t turn on. constant restart or shutdown
Most likely, this is a hardware problem, not always, sometimes reinstalling windows 10, Windows 7, Windows 8 or Windows 8.1 (depending on which one you use) solves it.
Hardware problem, may be due to high dust content in the processor. In this case, you may hear a loud fan noise and notice a constant reboot.
When you hear the sounds produced by the device, it’s better than nothing. Silence can indicate the general and final death of the laptop.
Usually, if it screeches, but does not start, the sounds are produced by the BIOS, and thanks to them, you can pinpoint where the problems are. Let’s consider the set of sounds in the BIOS Award system. In AMI Bios similar.
A short single beep means the system is working properly. After that, it should continue with a normal start.
Two short beeps are a reassuring sign. The system indicates minor faults.
Three beeps. keyboard error. A complex combination of 1 long and 9 short beeps indicates that the data cannot be read from the disk.
Black screen on laptop and won’t turn on. what to do
As I wrote above, the reasons why laptops won’t turn on can be very prosaic, but unfortunately, this is not always the case.
There are times when a hardware failure occurs. then you have to take into account significant costs. A black screen in a laptop may be for this very reason.
If you hear sounds of operating components when you press the power switch, connect an external monitor (maybe a modern TV) to the VGA or HDMI jack. This procedure will bring you closer to figuring out what makes only a black screen see.
If the image appears on the external screen, it means that you do not need to change the card. it works and interacts correctly with the monitor. In this case, you need to check your operating system settings.
Perhaps the screen was simply turned off, and the connection to an external monitor was activated. Pins in the case connecting the screen to the rest of the computer could also be damaged.
What if there is no image on an external monitor connected to the laptop? There are many signs of card failure. What to do in this situation?
Laptop does not turn on at all. check power
Please note that this can be either an old or a new laptop. You press the “On” button, wait and. it does not turn on. the device does NOT respond to our actions, even if we try to turn it on once, twice or 5 times.
Relax and start by eliminating the obvious reasons. Black screen in laptop can be caused by full battery discharge.
Then it is necessary to connect the power source, only sometimes the laptop does not turn on when working from the network, but this does NOT mean that it has already come to the end of life.
You need to carefully check the power supply and socket in the laptop and even the electrical outlet.
You need to look at the cable, and whether it is damaged, not worn out and in what condition the plug in the power socket.
If you can, try running it on a different battery or PSU. The use of non-original, as well as cheap power supplies can sometimes lead to a short circuit. this is not always the case, but many confirm.
If the power supply is on and the laptop won’t turn on, turn it on again, but this time listen to how it reacts.
You need to check if the hard drive and fans are working. It is also worth seeing if the light diodes (indicators) are on, confirming the start.
often than not, when you hear the sounds of running components and the laptop does not turn on, or to be more precise, you only see a black screen, it is very likely that you will need to replace the card.
The laptop turns on and does NOT boot further
The source of this problem could be the BIOS, or more precisely, its settings. Try to set the default settings.
This function may be in different places in different BIOS, but its name usually looks something like this: “default BIOS settings”.
It is also possible that after starting the system, you see the message “Press F1 to continue”.
Usually this issue occurs when a battery is installed on the motherboard (not the main battery), shows incorrect time or BIOS settings.
Another problem could be the hard drive. You can determine if it emits a squeak or pops.
There could also be a problem with the RAM. Maybe you just need to unplug RAM and clear contacts.
Laptop does not turn on. replace card
A malfunctioning graphics card can be a serious problem. In this situation, it seems to us that the laptop is not working, but in fact it works, but does not display an image on the screen.
The thought immediately arises of replacing the old card with a new one. The problem is that on most laptops, you cannot replace the card yourself.
On many models, especially low-cost ones, graphics cards are integrated into the motherboard in the form of a BGA chip.
To replace it then you will not only need a lot of knowledge, but also the corresponding equipment.
The more expensive ones have separate graphics cards, but in this case, replacing this module will not be an easy job.
As a rule, replacing it without Special Tools borders on a miracle. Then the only option is to use the services of a professional, proven repair service.
Replacing the card is so difficult that you may need to first remove the hard drive, Wi-Fi module and matrix, keyboard and GPU cooling.
As you can see, to get to the map, you need to disassemble most of the device, and then you need to fold it all.
There may be other damage that will lead to the fact that your laptop will not be able to turn on. Sometimes the motherboard needs to be replaced.
Laptop won’t turn on. BIOS problems or hardware errors
The mobile computer starts up, the indicators are on, but after 1-2 seconds the device turns off. Most likely, in this case, a physical failure. Reinstalling Windows won’t help here.
Such symptoms indicate that something is wrong with the BIOS and may need to be restored.
If you are sure that the bootloader is NOT damaged, this indicates a problem with the motherboard or microchip.
There are many reasons: incorrect connection of a defective device via USB, processor overheating, short circuit, and others.
Table of the most common software and hardware failures
Below you will find the most common problems with a laptop with a description and recommended solution to the problem.
That’s all. I tried to PROVIDE the main reasons why the laptop does not turn on the toshiba satellite laptop, irbis, Samsung, Sony Vayo, dell inspiron, Acer aspire, emachines, prestige, del, dns, Packard bell and others.

DO NOT describe everything. I watch the recording and it turned out far from small. If you DIDN’T find help in this article, write in the comments and I will try to GIVE you personalized help.
Let’s start by looking at a simple computer restart. It helps only when the OS reacts to user actions, but very slowly.
You must do the following (for example, Windows 7):
- In the lower left corner, click on the Windows image.
- Near line “To finish work” dubbed an arrow.
- Click on the command “Restart”.
All that now remains to be done. it is to wait. The computer will terminate all processes and then reboot the operating system. Laptop freeze? What to do in this case?
The laptop is frozen. what to do? How to restart a laptop if it freezes
User laptop stuck? What to do? We will have to answer this question further. After all, every user can face a freeze of the operating system. Often, in the case of laptops, you can reboot the PC using a more extensive list of techniques. They will be discussed further. Unfortunately, restarting the OS in case “glitches” not always safe. And this must be taken into account first of all. Therefore, we will try to study the safer overloading techniques first.
How do I restart my laptop if it freezes? Sometimes it happens that the operating system stops responding to any user actions. In this case, as a rule, a reboot does not help. I have to emergency shutdown the laptop.
You can also do this in several ways. We found out why the laptop freezes. Regardless of the cause “glitches”, in some cases, the user must emergency shutdown with the OS. To do this, just press the laptop power button and hold it in this position for a few seconds (5-10).
What will happen? The computer will be emergency shutdown. After enabling it, the user will be offered several options for loading the operating system. for example, in safe mode and in normal.
Old OS and reboot
We managed to find out why the laptop freezes. And we also had to familiarize ourselves with the main ways of reloading the OS. How exactly to proceed? Each user decides on his own, taking into account the auto goods situation.
Laptop freeze? What to do? For older operating systems, you can only restart your computer using the keyboard. Not always, but very often.
The user just needs to press Ctrl Alt Del several times (with short pauses). After that, an Emergency PC restart will be performed.
If the computer “buggy” and does NOT reboot in the usual way, you must force restart the OS. This is a normal phenomenon, the technique is used in practice quite often.
You need to act like this:
- Press Ctrl Alt Del on the keyboard.
- In the lower right corner, click on the arrow button. Next to it there will be an image of shutting down the PC.
- Select the function in the menu that appears “Reboot”.
It is done. In fact, everything is not as difficult as it seems. And now it is clear what to do if the laptop has a black screen or a simple freeze. But this is just the beginning. In reality, there are several more ways to deal with “glitches” laptops.
Coming to help
What if my laptop has a black screen? The previously listed techniques will help to correct the situation. But what if they did NOT work?
Under certain circumstances, users can try to shutdown the laptop like this:
- Disconnect the power cord.
- Flipped laptop.
- Disconnect the battery from the main body.
- Insert it back.
It is done! After the above steps, the user can turn on the computer again. This technique is not relevant for all laptops. It is not suitable for devices whose batteries are NOT removable. Therefore, removing a battery does not always help to get rid of “glitches” and freezes.
Sources of problems
Laptop problems can happen at any time. As a rule, this leads to slow operation of the OS, and then to a complete freeze of the computer.
The most common causes “glitches” are the following factors:
- software incompatibility;
- lack of RAM;
- processor load;
- system failures;
- incorrectly installed operating system;
- Downed OS settings.
Often, a rollback of the system or an increase in RAM helps to correct the situation. But first you have to turn off your PC. Laptop freeze? What to do? How do I reboot or shut down my laptop? All possible options for the development of events will be discussed below.
Eating and waiting
How to restart a laptop if it freezes and does NOT respond to user actions? It all depends on the circumstances. After all, sometimes it is possible to reboot by simply disconnecting the laptop from the network.
What if my laptop has a non-removable battery and is powered directly from power? Similar circumstances, if you exclude shutdown using the Power button, predict only one scenario. expectation.
What does it mean? You need to follow these instructions:
- Unplug the laptop from the power cord.
- Try to restart the computer using the previously listed methods (using the keyboard).
- Wait a few hours.
You can do without step 2. That is, just unplug the laptop and wait. True, you need to be patient. the wait will be long. Until the device battery is fully discharged. Even in a freeze state, the OS consumes energy.
What will happen? The computer will just run down and shut down. After that, it remains just to connect the laptop to power through the wire, wait a few minutes (not necessarily, but desirable), and then turn it on using the Power button.
Reboot without shutting down
Laptop freeze? What to do? If the operating system is still responsive to user input, you can try to restart without shutting down the computer. This practice exists, but it is not used very often.
So, it is proposed to act like this:
- Open in any way (via “Start” or Ctrl Alt Del) function menu.
- Select item “Log out”.
- Wait a while.
So users can re-enter the operating system without shutting down the computer. Although, as practice shows, exiting the OS is rarely used in practice.
Troubleshooting the problem yourself
Attention! We are NOT responsible for your actions. This article is for informational purposes only and has NOT won the Cup for Action.
The first step is to make sure the laptop is charged and the battery is working properly. Connect the laptop to the network (if it was running on battery power), wait a bit, and then try to turn it on again. If this time the screen lights up, then the problem most likely lies in the battery. Disconnect the laptop from the mains and try to turn it on from the battery again to make sure that the problem is correctly identified.
If the laptop does not work either from the mains or from the battery, try resetting the hardware settings:
- Disconnecting the laptop from the outlet.
- We take out the battery from the device. In most modern laptops, removing the battery requires disassembling the case, which requires a special tool and knowledge. Better with a similar one Contact the professionals.
- Press the power key and hold it for about 20 seconds to remove the residual charge and reset the hardware settings.
- Reinstall the battery and try to turn on the laptop.
If these steps did not help to solve the problem and the screen remains black, then you need to check the physical health of the display.
If when you press the power button, the screen remains black, but you can hear that the cooling system has started working and other signs of turning on the laptop are visible, then we try to connect an external monitor to it.
If a picture appears on the external monitor when you turn on the laptop, then the problem clearly lies in the laptop screen. Perhaps his matrix or loop is damaged, but you can hardly diagnose this yourself. But before you seek qualified help, try two more ways to fix the problem, described below.
Reasons why the screen remains black when you turn on the laptop
There are several reasons why you see a black screen instead of the desktop:
- Map problem.
- Damage to the motherboard due to overheating of the device.
- Faulty loop or screen matrix.
- Battery failure.
- RAM failure.
- Incorrect hardware settings.
The last three problems can be dealt with at home; it is difficult to diagnose a physical malfunction of laptop components on your own, so you will have to contact a service center.
When you turn on the laptop, the screen is black. Reasons and what to do
In this article, we will give an answer to the question why, when you turn on (boot, start) a laptop, a black screen and what you should do in a similar situation. If it still beeps, then you will find the answer in the article Why the laptop beeps when turned on.
The laptop does not boot because black screen, or starts up, makes noise but the screen does not turn on. the situation is not the most pleasant, moreover, it requires an immediate solution to the problem. This problem is widespread and often requires professional intervention. one of the components of the laptop is damaged and it needs to be repaired using special equipment.
If you updated the BIOS or changed its settings before the problem appeared, then you need to Rollback all changes. For this, it is better to use an external monitor if there is an image on it when you exit:
- Turn on the laptop by connecting an external monitor to it.
- Go to BIOS (Delete or F2 key at startup).
- Press F9 or on the “Exit” tab select “Load Setup Defaults”.
In principle, these actions can be performed blindly, because all commands in the BIOS are entered from the keyboard, without the involvement of the mouse. After BIOS reset, disconnect the external monitor and check if the screen works.
Reinstalling the RAM module
Another prerequisite for the appearance of a black screen is a malfunction of the RAM module. This is especially true for a situation when liquid got on the laptop, after which it stopped turning on.
Important: The described actions are not recommended to be performed on your own if you have relevant experience.
- Unplug the laptop and remove the battery from the laptop.
- Remove the bolts that hold the RAM cover. If there is a compartment, then you will have to remove the back panel of the laptop.
- Locate the RAM board and carefully remove it by bending the latches to the sides.
If none of the described methods helped to deal with the black screen when turning on the laptop, then the best solution would be to contact a specialist who can correctly diagnose the cause of the problem and quickly fix it.
A white screen is unpleasant, but the good news is that there are few reasons for it. You can check them all yourself, but not all are renovated at home. In any case, by following the recommendations proposed above, it is quite possible to get rid of the problem, but if this does not help, then the service center will come to the rescue.
A white screen on a laptop is a sign of a malfunction of the card driver or the monitor itself, or the action of viruses. The first thing that needs to be done when such a situation arises is to install an antivirus on the laptop and carry out a complete cleaning of the system. If this cannot be done due to the fact that the device does NOT have time to complete the procedure for searching and eliminating viruses due to the appearance of a white screen, you should enter the safe mode and clean it.
A good option for such cases is to use the Dr.Web CureIt utility. It is free and does not require installation on the device. It is quite simple to work in it, you just need to select the directories that you want to check, and then click “eliminate threats” if any viruses were found. However, the choice of antivirus is a personal matter of each user, so there is no specific recipe here.
If cleaning the gadget from malicious software did not help get rid of the white screen, then you need to update the drivers. There are several options. download them directly for devices responsible for graphics, or update all software at once. It is better to update everything, since the update, in principle, needs to be done regularly.
There are special utilities that allow you to automatically carry out all the procedures. Driver Pack Solution is a good example. The user is required to launch it, then the program itself will find all the appropriate update package for all device drivers.
If the screen turns white when you turn on the laptop, or it is not completely white, but with stripes, then this is a sign of hardware damage. In this case, there may be three damaged nodes:
- ribbon cable from the motherboard to the matrix;
- damaged matrix;
- malfunction of motherboard components.
Before going to the service, it is recommended to check the reasons for the failure yourself. Obviously, it will not work to repair the motherboard at home, so it remains an extreme option, and the user can only hope that it is not about it.
To check if the matrix is damaged, just connect a monitor or another laptop to a laptop via HDMI and VGA. Further, on the keyboard, you should find a button that switches the picture from the native screen to the additional one. It is located on one of the F buttons with the drawn screens. Pressing it and Fn at the same time can start displaying on the spot monitor. If the picture appears, then the problem is really in the matrix itself. What happened to it, concepts are impossible without disassembly, but there are a lot of reasons for breakdown. shock, burnout, end of service life. In any case, a trip to the service center is required to replace the display.
If the matrix behaves incorrectly during operation. a white screen appears, the picture flickers, stripes appear, or when you try to change the position of the display, the image stops being displayed, it is likely that the problem is in the loops. It is impossible to change them on your own, and moreover, when the loop breaks down, the entire matrix is usually changed. But sometimes the problem is that they have moved away from their mounts, and it is enough just to reconnect everything.
To check the functionality of the loop, you need to disassemble the laptop, for this you need to find a disassembly diagram or an overview. Further, it is worth visually assessing the condition of the plume: mechanical damage is visible, it can be a fracture, crack, black plaque and other signs. If nothing of the kind is noticeable, then you should disconnect them and reconnect. It is quite possible that after this the problem will go away by itself.
Reasons for the appearance of a white screen on a laptop
One of the problems that a user may encounter with everyday use of a laptop is a white screen. This phenomenon is infrequent, but possible, so you should figure out what caused the white screen on a laptop. The reasons can be divided into system and hardware reasons. The first group is removable at home, the second will require contacting a service center.
What to do if your laptop won’t turn on?
After reading this article, users will be able to independently, without the help of a specialist, deal with some NOT complex problems arising in Asus, Acer, HP, Apple, etc. laptops. To do this, you do not have to contact the service center. But if the problem is more serious, then it is better to contact the specialist of the FixCenter service center. You can do this in different ways: by sending a request on the website, write a message in the chat, or call by phone. These steps do NOT take much time, but there will be more opportunities to fix the laptop.
Let’s figure out what to do if the laptop does not turn on. If you ask a specialist from the service center that provides technical support, it immediately becomes clear that many users cannot correctly describe the occurred malfunctions. And this applies not only to unprepared users, but also to people with a good set of knowledge and skills in computer repair. Perhaps for someone the information provided will seem elementary and does NOT require explanation. You must remember THESE truths when breakdowns appear.
If you make an accurate diagnosis, then most of the case will be considered completed. Here is the correct description and explanation of the malfunction, the result of the engineer’s work depends. For example: if the user cannot turn on the computer, or when the laptop is turned on, the screen is black.
Hard disk (hard drive) does not boot, hdd is not visible
Some users confuse it with loading the operating system. When this defect appears, in comparison with the previous ones, it is usually easy to enter the bios. With such a malfunction, the laptop may behave differently. It may freeze during the BIOS splash screen, constant spinning of the cursor showing that the laptop is trying to boot. The cursor may appear on a dark screen and display a message about the use of a non-system disk.
The possible cause of this problem lies in the following points:
- Hard disk malfunction (use of a non-working uninitialized controller, mechanical damage to media, dietary supplements).
To eliminate this defect, you just need to remove the old hard drive to use the new one.
- Problems with the South Bridge, which has a hard disk controller.
You can fix the problem by completely disassembling the computer and then replacing the south bridge.
Shutdown, reboot when BIOS initialization and BIOS splash occurs
Some users confuse it with reboot, which is started during RAM startup. These overloads differ in the time of periodicity of actions. In this case, the operation takes three seconds.
He says how the laptop behaves in this case. You can talk about possible behavior in several cases:
- The South Bridge is out of pace. Usually, this is caused by a short circuit, a breakdown arising from the usb connector and breakdowns occurring in it.
To solve this problem, you need to completely disassemble the laptop, then completely replace the south bridge.
- The processor, the north bridge is overheated, the cooler is forgotten with dust, the heatsink is loose. Because of all this, the fan produces fast turns and turns off in different ways.
You can solve the problem by completely or partially disassembling the laptop and then inspect the cooling system, clean the laptop from dust particles, check the correct heat sink.
- The power supply does NOT supply power. The laptop is attempting to use the battery for starting. Since the battery is already low, the computer immediately turns off and the screen goes dark.
To eliminate this defect, replace the power supply. Better to use new parts. Information about can be found on the company’s website.
- BIOS chip or firmware has gone bad.
You can fix this problem by flashing the BIOS. To do this, use the crisis floppy disk. If there is a sense of using it or there is no possibility of using a floppy disk, you need to completely disassemble the computer in order to replace the damaged elements if necessary and then reflash everything again.
None Initialization (black screen when turning on laptop)
When you turn on the laptop, a black screen, when you press the main power button, you can hear the operation of the cooler spinning without stopping. He carries out high revs. Together with it, the light of the indicators of different buttons will turn on. They are on, but the computer does NOT boot and there is NO light on the screen. There may be different options with the operation of indicators, only the cooler still works. The image does NOT appear on the display, and the hdd indicator does not flash. Often users confuse this problem with the problem of the absence of a picture on the display and the presence of an image at the borders of an external monitor.
If a black screen and the laptop does not turn on, you need to look carefully, if there is no download at all, This does not mean that the matrix is in a faulty condition and does not have images at all.
- A problem arises due to a malfunction of the processor, memory (with poor contact in the processor, memory module, connectors, lack of supply voltage).
To solve this problem, you need to completely or partially disassemble the laptop and make its subsequent diagnostics. Check supply voltages, juggle or replace these elements. If they are missing, then install.
- Problems with a broken BIOS firmware.
To solve this problem, you need to flash the BIOS with a special disk. If it is not there, then you will have to completely disassemble the laptop, solder it, replace the necessary elements, BIOS chips, reflash with the introduction of the programmer.
- Northbridge or chip issues.
To solve the problem of a non-working chip or north bridge, you need to completely disassemble the laptop and then diagnose the supply voltages, generate clock frequencies, replace faulty microcircuits.
Power supply does not work (charging, AC adapter)
Due to this malfunction, there may be a permanent black screen when starting the laptop. If it charges the battery, the computer will function. Correct display of operating system charging. Then it gradually decreases, even when the computer is turned on to the network.
A similar phenomenon occurs for the following reasons:
- Power supply or plug in malfunction, broken.
You can fix the defect by repairing your laptop. If poor contact of the board with the connector, replace the connector. It may have broken. In case of broken wires, replace the power supply on the laptop.
- Faults in the power and charging controller.
To fix the problem, you need to completely disassemble the laptop, diagnose the supply voltages, replace the defective parts of the device.
The operating system does NOT boot. The laptop restarts while it boots
It can happen at any time. Only the operating system is loaded first. At least 3 seconds should pass. It occurs for the following reasons:
- The system is infected with viruses. This causes the computer to restart.
You can fix this problem by using an external bootable media and checking the disk with the popular antivirus.
- The operating system may have just crashed.
To fix this problem, you need to reinstall your operating system. This method helps in many cases. The second way to eliminate the defect is difficult. The actions are not so complicated, an ordinary user can handle them. Routine reinstallation or search for causes of overload.
- I am having memory or processor problems.
You can solve this problem by replacing the faulty component. To do this, you can contact FixCentr.
- In rare cases, the appearance of microcracks in the motherboard. This happens if the computer is under non-linear loads. It is pulled in opposite corners, bent.
The problem can be eliminated by diagnosing the board with coils, connectors and bridges. Then they solder, replace the faulty elements with new ones.
Laptop screen does NOT light up when the power button is pressed
This can be said if there is no reaction when the user turns on the laptop. That is, the device is NOT active, you can hear the fan operation, you cannot see the lights up. It seems as if in front of you is an ordinary piece of plastic. When the laptop is turned off, the indicator showing the battery charge is on or off. This fact is immediately mentioned when describing the malfunction. Such behavior in a computer can occur for various reasons:
- The laptop does not turn on if the power supply (charging) burns out, there are batteries, it is dead or inoperative. When the button is pressed, you can see the light come on to indicate battery charge. The laptop does not start up. The reason is: the battery is discharged or there is no voltage in the power supply.
To solve this problem, you need to install a new charger or power supply. The cost of this device can be found on the website of the Fixcenter company.
- There is BIOS firmware or it has become broken. You need to flash the BIOS using the crisis floppy.
If it is absent, then you need to completely disassemble the laptop, then solder, replace the BIOS chips, reflash using the programmer.
- There is no contact inside the power connector (there was a breakdown of the central contact, the connector moved away from the oregano in parts or completely; the wire in the cable broke and other problems associated with the breakdown of the connector).
To successfully solve this problem, the connector needs to be repaired. If there is poor contact with the motherboard, then it is replaced. If the connector breaks down, the wires are broken, it is repaired or replaced. You can find out the cost of this part on the FixCentr website on a special page.
- Lack of firmware or use of broken firmware.
- You need to look at the motherboard with internal circuits. The problem may have appeared due to a short circuit. They look at the circuits, the battery, the burnt out microcircuit, perhaps the duty room.
To solve such a problem, it is necessary to completely disassemble a Sony or Asus laptop, make subsequent diagnostics of each supply voltage, generate clock frequencies, replace defective elements.
- the chip, south or north bridge has undergone a short circuit due to overheating (this happens in AMD, ATI, nVidia chips), breakdowns in the UESB.
You can solve this defect by completely disassembling the laptop and make subsequent diagnostics of the supply voltage, generate clock frequencies, replace faulty microcircuits, replace faulty nVidia microcircuits, south or north bridge.
The battery on the laptop is NOT charging (the charge does not increase in percentage, there is no charge indication)
From these parameters, you can determine that the network is supplying energy to the computer. The device can turn on if the unit is supplied with power. The operating system displays an icon that the computer is using the electrical network for power. Battery charging icon is NOT displayed. Similar problems arise not only from a dead battery.
This can happen due to the following reasons:
- Due to non-working batteries.
You can solve the problem by replacing it. Better to do so so as not to overpay a huge amount for repairs. This is a more reliable solution. The cost of batteries is not that high.
- Malfunctions in the power and charge controller.
You can solve it by completely disassembling the laptop, diagnosing the supply voltages, replacing the faulty parts.
- External power supply requires additional power.
To fix this problem, you need to replace the power supply unit by choosing a more suitable power. To determine it, just look at the case on the entry on the laptop under the inscription Input.
What to do if your laptop won’t turn on?
Any master engaged in the repair of computer equipment, especially laptops, it is clear that in order to speed up the repair process, the user must be able to understand the minimum malfunctions of a laptop.
It is enough to go to a search engine to prove this belief. All masters say the same thing. It doesn’t even make sense to repeat the same phrases after them. The same aLGorithm of actions is used everywhere. A user who has spent a lot of time at a computer should be clear about this. After all, it is stupid to contact a professional every time because of the slightest malfunction when starting Windows. But sometimes there are more complex malfunctions when the laptop does not turn on or when the laptop turns on a black screen.
You need to at least understand why the laptop does not turn on and where the problem came from. Perhaps there is nothing serious and there is no point in calling a master on every occasion. Unless the motherboard is damaged. Then our advice from this publication will not be enough.
To repair this basic element in a computer, you need to have the necessary tools as well as skills. The fact that users cannot do without tools only in the process of disassembling the laptop. Due to the lack of necessary elements, the laptop has to be reassembled, but with difficulty. It will seem that somewhere a part has broken off or a circuit has closed.
