How to enable touchpad on Lenovo laptop

The touchpad, or touchpad, is an essential component of all Lenovo laptops. This is a compact version of a USB mouse. On the one hand, this is a very convenient thing, since it eliminates the need to use a wired mouse, but on the other hand, using the panel is not always comfortable, because it is located near the function buttons.

Today we’ll talk about how to turn on the touchpad on a Lenovo laptop if it stops functioning.

Through the “Control Panel

To connect the touchpad on a Lenovo laptop in this way, go to the “Control Panel”, select the “Mouse” section there, and there. “Device Settings”. In the tab you will find two functions: “Activate” and “Deactivate”.

Check the boxes and the sensor setup on your Lenovo laptop will be done.

Driver problem

Drivers may have failed due to a failure due to reinstallation of the operating system. Without them, the panel may not function partially (for example, only gestures broke) or completely.

Often, a driver disc comes with a laptop. But if there is no such disk, then the driver should be downloaded from the manufacturer’s resource. You can find them there in the section called “Service”. When performing a download, you should pay attention to the following data:

  • Bit Windows (x64, x32, x86);
  • The version of the installed operating system;
  • Device model.

The ultimate compatibility can be achieved only if all three parameters match. However, there are some exceptions: if the bitness of the OS must be 100% the same, then a different version of Windows is allowed. For example, on Windows 10, drivers from the 8th “Windows” will function perfectly, but provided that there are no updates for the 10th version.

If you download the drivers as an executable file (.exe), you can install it like a program using the installation wizard. If the latter does not start, then you should add the drivers manually. The action plan is as follows:

  • Go to the control panel, set the “Big icons”, start the device manager.
  • Using the cursor on a Lenovo laptop, open the section titled “Mouse” and select “Touchpad” there. Right-click on it and select “Properties”.
  • Verify the normal operation of the device.
  • Go to “Drivers”. First of all, try to roll back the software by clicking on the button of the same name. If this does not work, select “Update”.
  • A window for selecting the update modes will appear. If the required software has been downloaded, then select the manual installation option.
  • Assign the path to the drivers, wait for the installation to complete.

After reinstalling the drivers, restart the laptop. During the launch, check the panel: if you still cannot turn off / turn on the touchpad on a Lenovo laptop, then most likely the reason is mechanical damage. Broken can be:

  • A microcircuit that ensures the functioning of peripheral devices. In this case, LAN and USB usually do not work;
  • Sensor;
  • Flex cable that connects the touch panel to the “motherboard”.

You can also disassemble the laptop yourself, following the instructions supplied with the device. However, it is best not to do this, as unprofessional intervention can exacerbate the problem.

We’ve shown you the most effective methods for activating the touchpad. If none of them helped to solve the problem, then you should contact the wizards for help. Maybe the panel is just faulty. The cause of the malfunction may be associated with moisture ingress, poor contacts, mechanical breakdowns. The service center staff will conduct a thorough diagnosis, identify the cause of the malfunction and quickly fix it, bringing the touchpad of your laptop back to life.


Almost all modern laptops. Apple, DELL, Xiaomi, Acer, Fujitsu, HP, Lenovo, Toshiba, Samsung, Sony have key combinations that allow you to disable and enable the touch panel. Basically, this is a combination of the “Fn” key and one of the function keys (F1-F12). They should be pressed at the same time.

It should be noted that the combinations will differ for different brands of notebooks. Let’s look at the example of the most popular laptop brands, which of them should be used when the touchpad does not work:

  • Acer uses a combination of Fn F7.
  • Asus may have two variants Fn F9 or Fn F7.
  • Lenovo has two types of combinations Fn F8 or Fn F5.
  • In Samsung, Toshiba, Dell, you must press the Fn and F5 keys at the same time.
  • If the laptop is Sony, then you need to press Fn F1.
  • At MSI. FnF3.

This list does not include a common HP brand, since devices of this brand have a special button for these purposes, which is located under the keyboard or on the touch panel itself (it is worth looking for a point or depression).

Just reboot

Sometimes a simple restart of the laptop is enough for the touchpad to work properly again. You can reboot using a computer mouse. If for some reason it is impossible to do this, then you can use the keyboard. The solution options here may be different:

  • Open the “Start” menu, press Win (the button with the Windows logo applied). Then we use the arrows to select the “Shutdown” item, press Enter and select the “Restart” line.
  • By simultaneously pressing the CtrlAltDelete keys, go to the Start menu. Further, as in the first case.
  • Press AltF4 and choose restart.

Careless actions can be dangerous, as you can disable not only the touchpad, but also other parts of the system, or even disable the entire system. And to prevent this from happening, read carefully the instructions that we give below.

Installing drivers on Windows

The most common reason for a lack of response from a touchpad is incorrect or missing software. In order for it to turn on, the drivers corresponding to it and the operating system are required. You can find a driver for your device on the official website of the laptop manufacturer, after that you need to select an operating system and install it.

Updating or downgrading the touchpad driver

Locate the Touchpad device, usually named after the laptop brand (Dell TouchPad, Lenovo TouchPad, Synaptics, HP TouchPad, Acer TouchPad, Asus TouchPad.) Right click on your driver and select properties. Next, click Update to see if there are any useful updates for your touchpad.

Many people have reported on the Microsoft forums that the Touchpad stopped working exactly after updating Windows 10, for this you need to choose to roll back the driver. If you do not have the Rollback button highlighted, then you do not have a previous driver version.

Touchpad not working on laptop? 5 Ways to Solve the TouchPad

The touchpad is an age old feature that has long since replaced alternative mouse controls. With it, we can fully control our device, be it a laptop or a hybrid tablet. Many laptops (Acer, Asus, HP, lenovo, Dell) have problems with the touchpad. What to do if the touchpad does not work on a laptop in Windows 10? Let’s take a look at 5 ways to fix this problem.

Re-enabling the touchpad using the Fn key

One story happened to me when I turned on WI-FI on my laptop and inadvertently turned off the touchpad touchpad. For a long time I was looking for the reason, not immediately realizing what had happened. Everything turned out to be simple, in laptops there is a button for additional functions called Fn from the bottom left of the keyboard. To enable any function on a laptop, the combination of the Fn and F1 buttons is clamped. F12. On these same F1-F12 buttons, pictures or symbols are drawn to apply the parameter. For example, to turn on the touchpad, you need to press FnF7, on the F7 button itself there will be an image like a touchpad. You can press all buttons in order FnF1. F12, but remember that there is a function to turn off the display, press again on those buttons on which the screen went out.

On some HP notebooks, the touchpad can be turned on and off by double tapping on the edge of the touchpad itself. Asus and acer brands may have a separate button next to the touchpad. If the touchpad still does not work, then move on.

Enable touchpad in mouse properties

In many cases, the device manager does not fire in order to enable Touchpat on a laptop. If your Touchpat still does not work on a laptop in Windows 10, then go to properties mouse.

  • Type mouse in the Windows search bar and go to Mouse Preferences.
  • Click Additional mouse options, in the window that opens, go to Device Settings, the Touchpad tab or as in the picture.
  • Find your Touchpad and click “enable”.

Removing Other Mouse Drivers

There are times when in the past you have connected a whole bunch of drivers from different mouse devices and you have never uninstalled them. Some drivers from mouse manufacturers themselves automatically disable the Touchpad. Go to Device Manager by pressing the WinR button combination and type devmgmt.msc in the line.

Find the line pointing to mice and other pointing devices, click on the shortcut to expand the category and delete all the mouse drivers in order until the touchpad starts working on your laptop. If it does not work, try restarting the system after removing all drivers. Touchpad not working? Moving on to the next item.

The touchpad does not work on a laptop: 5 ways to solve the problem

What to do if the touchpad on a laptop stops working? You should not immediately carry it to the service. The bottom line is not always a hardware failure: it may be incorrect operation of drivers or another software failure. Simple actions that even an inexperienced user can do will help to revive it.

Updating or reinstalling drivers

Regarding software problems, they can manifest themselves in different ways: scrolling does not work, the touchpad does not respond to a click. Functionality is usually only partially lost. In this case, you need to scan the system with an antivirus and see the status of the drivers.

You can update, roll back or uninstall the program in Device Manager, Mice tab. The touchpad is referred to as a HID device or TouchPad. The problem is signaled by a yellow triangle. Installing the official software expands the touchpad functions.

Sometimes the touchpad doesn’t work after downloading new programs. Then the system rollback will help restore the device to work.

Cleaning the touchpad

Often the touchpad on a laptop does not work due to common pollution. To remove grease and moisture, the sensor must be wiped with special napkins or a lint-free microfiber cloth. The sensor surface must always be kept dry and clean.

Turning on the sensor

It is necessary to check the activity of the sensor by simultaneously clamping Fn F2-12. Often the touchpad does not work because it was previously turned off. In different devices, an individual set of keyboard shortcuts is provided for performing actions, for example, in Asus. FnF9, and in Lenovo. FnF6. In some variations, the sensor power key is displayed on the panel itself. It looks like a barely noticeable depression or dot. In this case, the touchpad is activated by double clicking on it.

GPT and MBR standards

In rare cases, the touchscreen on a laptop does not work due to a system error. The problem lies in the disk code that is required to boot. There are two standards presented: GPT and MBR. The first is a GUID partition structure that carries information about the hard drive partitions. It is part of UEFI, which newer PC models use instead of BIOS. The second acts as a memory segment containing the boot loader for the operating system. MBR is a traditional structure and is compatible with all operating systems. The first option has a drawback. this standard does not support old systems, which is why a systemic conflict arises.

The error is resolved as follows: you need to see which segment is implemented on the laptop using the command line. The window opens with a combination of WinR. The line is entered “diskpart”, after. “list disk” and “Enter” to select the transformation structure. If there is an asterisk in the list that appears in the last column “GPT”, then this is the first version of the standard. If it is empty. the second one. In the first case, we can assume that a system conflict interferes with the touchscreen. The standard of the system disk is changed without losing data using special software. Alternatively. AOMEI Partition Assistant.

If you follow the instructions, performing the actions step by step, then the result will be to quickly eliminate the malfunction.

Driver failure

When the touchpad does not work on an Asus laptop or any other, it is first of all recommended to check the availability and freshness of the drivers for the device. Go to the “Device Manager” and find there the item related to the touch input device. Further actions depend on the opened picture.

Perhaps Windows 7, Windows 8.1 or another system incorrectly installed the driver on the new laptop, having done it twice, and now it is confused about which device to access. In such a situation, you need to right-click on one of them and select “Remove device”; perform the same operation with other unnecessary devices, and then restart the laptop. After rebooting, the system should automatically pick up the necessary drivers, and the error will disappear.

If the device is displayed as needed, in a single copy, then updating or rolling back drivers can help. This is especially true if a yellow exclamation mark is displayed at the name of the touchpad in the “Device Manager”. Move the cursor over this name and bring up the context menu. Select Properties from the list. In the window that opens, select the “Driver” tab. Then proceed according to the situation. For a start it is worth trying “Update” software. If the tap on the touchpad stopped working after updating Windows, then the option “Roll back” is provided. It will also not hurt to download from the official website of the laptop manufacturer, from the Drivers section, a fresh package of suitable drivers specifically for your device model.

Five ways to turn on the touchpad

When the touchpad on a laptop suddenly stopped working, this does not mean that the device is broken. Perhaps you turned it off accidentally. There are five ways to enable / disable the function:

On some laptop models (HP in particular) there is a small recess in the corner of the touch panel. Many do not know, but this is the very “magic button”. If you double-click on it, then the touch panel will be activated or, conversely, disabled. Alternatively, hold your finger can also be used instead of double tapping.

All models, without exception, have the ability to activate and deactivate the function with hot keys (Fn F1-F12). The pictogram drawn on it will tell you which key to press. For example, if the touchpad on an Acer laptop does not work, then you usually need to press the Fn F7 key combination. Table of popular manufacturers of laptops and hot keys embedded in them:

The touchpad can be disabled or enabled programmatically, through the Settings window in Windows 10. You need to go to the Devices section and find the “Touchpad”. The switch that is there must be in the “On” position. In addition, check next to whether the checkbox next to “Do not disable the touchpad when connecting a mouse” is checked. If it is removed, then immediately after connecting the peripheral mouse to the laptop, the sensor will be deactivated.

You can also try to solve the problem of why the touchpad on a laptop does not work through the BIOS settings. To get into them, hold down the Delete or F2 key while starting the device. Find Pointing Device in BIOS and set it to Enabled. Click “Exit with Saving” or a similar button to save the changes and restart the laptop.

Finally, you can look at the instructions for the laptop. But we are not talking about paper instructions, but about electronic documentation, which is usually more detailed. You can often find it on the C: drive in the Documentation directory.

You have learned the standard and manufacturer-specific methods for solving the problem. If none of them had any effect (for example, the touchpad on the computer is turned on for all points, but does not work), there may be a breakdown.

Why the touchpad does not work on a laptop?

If the touchpad does not work on a laptop, then some users will simply take and connect an external mouse to it, while for others it will become a serious problem. Laptops are bought largely because of their mobility and ease of use on the road. And in these cases, the touchpad is more convenient to handle than the mouse. In today’s article, we will consider the main possible causes of breakdown, and if you cannot cope on your own, you can contact us for laptop repair.

Purpose and benefits of the touchpad

For a portable device like a laptop, it is important to have as few moving, protruding, and pluggable parts as possible. It should be as self-sufficient as possible.

A small touchpad allows you to slide your finger over it and thereby move the mouse cursor. It also contains other functional actions. for example, tapping (tap, tapping) will mean clicking the left mouse button, moving vertically along the left edge. scrolling, etc. MacBooks also have a 3D touch function, when you can, using several fingers at once, zoom in or out of the picture, flip the image.

In addition, the touchpad usually has two buttons that act as the left and right mouse buttons.

For all its conveniences, the touchpad just gets in the way for many. Indeed, it is inconvenient to touch him while working with text or any other similar situation. Therefore, the developers have provided options to allow the user to activate or deactivate this area. It is also relevant if your laptop is on the table at home and it is more convenient for you to work with it with a mouse, as on a stationary PC.

Sensory service

If you are the lucky owner of a laptop with a touch screen, then the reason for the touchpad glitches may be in the resources that are not properly allocated between them. In hybrid devices, the touchpad and screen often conflict. At the same time, at first the touchpad starts to work poorly, slowly responds to pressing, and then completely fails.

In such a situation, you will have to choose between a touchpad and a touchscreen. If you find that you need the panel more, then you need to turn off the screen. To do this, press WinR, thereby calling the “Run” window. In the input field, type services.msc to open the list of system services. Find a service with a name similar to Tablet PC Input Service among them. Right click on it, click Disable. After that, the touch screen should stop working and the touch panel should start functioning normally.

If you bought a laptop to take full advantage of its functions, and are not ready to give up on them, then you can try to roll back or update the drivers for input devices (mouse, display). If the configuration is correct, then the conflict between devices will disappear. Or just remove both devices from the “Device Manager” and reboot. When turned on, with a high degree of probability, the system will install everything correctly.

The touchpad does not work due to hardware malfunctions

This happens after disassembly or after assembly. The most common reason is that after the dismantling was done, they forgot to plug in the power cable for the touch pad. Other prerequisites:

  • moisture has entered the sensor;
  • there was a temperature drop, due to which the loop contacts oxidized (therefore, you cannot turn on the laptop immediately after coming home from frost).

The plume generally oxidizes very quickly, this is the weak point of any touchpad. And oxidized contacts can no longer fully transmit signals. At the same time, the device often fails gradually: first, the keys or the scroll area stop working, and only then the main part breaks down.

serious breakdowns include cracks in the sensor or a malfunction of the entire south bridge of the laptop (the south bridge is a microcircuit that is responsible for the functioning of all connected peripherals). A cracked sensor can be replaced with a new one, and fixing the south bridge is purely for a specialist who knows how to disassemble and restore a motherboard.

So what if the touchpad on a laptop is not working? The first is to check that it is turned on. The second is to update the drivers. The third is to solve hardware problems. If this seems difficult to you, please contact our service center in St. Petersburg for a solution. We carry out diagnostics and quick repair of any computer equipment at low prices.
