How To Connect The Monitor To The Motherboard

Front Panel

The area of ​​the location of the power and reset buttons, as well as the power indicators, disk activity, sleep and Some of the second on the system unit is called the front panel. On the motherboard, it corresponds to the f_panel contact group.

How To Connect The Monitor To The Motherboard

F_panel can look like in the photo, where each contact is painted with a certain color, or it can be solid. The number and location of pins on it is also not the same, so the front panel connection diagram for motherboards, for example, Asus, will not fit Gigabyte boards and vice versa.

On some motherboard models, the front panel contacts are signed, which greatly facilitates the process of assembling the system unit.

But most often they are simply marked with serial numbers, as in the first photo. In this case, you cannot do without instructions.

How to connect the power button to the motherboard

Well, the components are assembled, the remaining accessories are equal to the second and. hello, new computer! If there are usually no difficulties with the connection of the processor, memory, card, then the small wiring connecting the contacts of the motherboard with the elements on the case of the system unit force you to scratch your head for a long time: which one leads where?

The pins for buttons, lights, system speaker, and audio connectors all look the same, and each motherboard manufacturer places them differently on their products. Today we will talk about how to properly connect the computer’s power button to the motherboard and NOT burn anything.


  • Foxconn motherboards have a 20-pin power switch pin 6 and 8.
  • On a 10-pin group. also 6 and 8.

On Epox products with a 20-pin front panel connector, the Power button is connected via pins 11 and 13.


Another exotic motherboard brand is Intel, available in 10- and 12-pin f_panel groups. The power button is connected to pins 6 and 8.


Biostar motherboards are NOT too common in our country, but models with the following PWRSW pin arrangement are more common:

  • On 16 and 24-pin connectors. 14 and 16 pin or 15 and 16 pin, if the contacts are counted along horizontal rows.
  • On a 10-pin connector. 6 and 8 pin.

On MSI boards, the f_panel connector has 10 pins, the Power switch pins are designated by serial numbers 6 and 8.

Fujitsu Siemens

On the 30-pin Fujitsu Siemens front panel, the Power On / Of pins are ranked 25th and 26th. Please note that the contacts on this board are counted from right to left.


In Gigabyte, front panel connectors are usually 20 pins. Power switch has pins 6 and 8.


Different models of AsRock motherboards have different arrangement of Power switch contacts. eg:

  • On a 10-pin connector: pin 5 and 6 or pin 6 and 8.
  • On a 20-pin connector: pin 6 and 8.

Power button

Here are the power buttons on the front panel of the system unit, there are 2 wires, which end in a rectangular connector with two holes and the inscription “POWER SW” (Power switch). DO NOT confuse it with the “POWER LED” connector, the latter is for connecting the computer’s power indicator.

The “POWER SW” connector connects to a pair of pins on f_panel, which are signed in the same way on the wiring diagram. On some circuits, Power switch is designated as PSW, PWR, PWR BTN, PWRSW or ON / OF.

The front panel contacts are polarized, that is, one of the pair of conductors is connected to the output “”, and the second. to “-“. The Power switch connector also has a minus and a plus, but it can be connected to the motherboard by either side, since it works to close / open a circuit.

But what happens to the computer if you mistakenly connect the power button to a second connector, for example, indicators or system speaker? It’s okay. it just won’t start, since the switching circuit, which is closed by pressing the button, will remain open.

Likewise, you should not be afraid of problems if you make a mistake with connecting the second elements of the front panel. An incorrectly connected element simply won’t work.

The process of connecting the front panel of the case of the system unit

The appearance of the connectors for USB and sound practically does not differ from those connectors that were described above in the article.

However, unlike the previous connector wires, they are connected together.

Each connector is named (USB and HD AUDIO respectively). The appearance of the wires is shown in the figure below:

Appearance of connectors for connecting USB and sound to the computer motherboard

The connector for connecting these connectors on the motherboard is located at its bottom and, as a rule, is signed with the name F_USB1 or F_USB2.

There can be more than two connectors for connection (newer versions of motherboards).

It doesn’t matter where to connect which wire.

All inputs are absolutely identical, the order of their connection does not affect the operation of the components on the front panel of the computer.

It is also impossible to go wrong with the correct side of the connector.

USB connector can be connected only one side.

Follow the instructions:

  • Find the connector named F_USB;
  • Locate the Matching connectors on the motherboard. Their location is shown in the figure;

Location of USB connectors on the computer motherboard

  • Connect the connectors to any of the connectors on the board.

Connecting all buttons and status indicators

On any case there are indicators for the status of the computer, LEDs, buttons, disk drives. Other elements may also be present.

On the computer motherboard, there is a separate block for connecting light-diodes (indicate the state of inclusion) and buttons.

Components to this box are connected using four SEPARATE connectors.

Their appearance is shown in the figure below. They look the same on all computers, however, the phrases that are written on them may differ (but they mean the same).

Connectors are painted in different colors.

Yellow is for connecting the power button, blue is for the system status diode (lights up when the system is restarted).

The green connector connects the power button indication light to the computer motherboard (after pressing the power button, the corresponding light turns green).

Red. power button cable.

The connector, which links the speaker on the cabinet, can also be painted yellow.

This speaker emits a beeping sound when the computer is turned on, when it detects system errors, or when connected to a wireless network.

Appearance of four connectors for connecting lamps and buttons

All connectors connect to one specific port on the motherboard. Typically, this port is located at the bottom right on the main system board.

Computer manufacturers refer to this port as PANEL and its variations (F_PANEL).

Absolutely every motherboard has signatures that indicate what and where to connect. The figure below shows the required port on the board.

The arrows indicate where you need to connect each of the connectors.

Port location and signatures for connecting connectors

On the main board, you can often find a separate connector for connecting a speaker, which reacts to errors in the BIOS and in the computer hardware.

The location of the connector is shown in the figure:

Speaker connector location

After connecting the block with buttons and diodes, you can start connecting all the front USB inputs, as well as audio outputs.

Now you need to connect your audio devices to the motherboard. All actions are almost the same as how to connect USB connectors.

The connectors are also connected together.

Thus, you can connect all components to the computer motherboard without error.

On most motherboards, all audio connectors are located near the USB connectors. The approximate location of the ports can be seen in the figure below:

Most often, audio connectors are signed as AC 97.

In order for the headphones and microphone to work correctly, it is necessary to check the device driver in the BIOS and compare it with the one used by the system.

They must be the same.

How to properly connect the motherboard

It can be difficult for an inexperienced user to connect a motherboard. The abundance of wires, connectors, incomprehensible symbols. all this raises a number of questions. This article will consider in detail the issue of connecting to the “motherboard” of all other devices, starting with the power supply and ending with USB connectors from the front panel.

Main devices when connected to the motherboard

1. Securing the motherboard to the case. Usually there are 4 racks (sometimes more, but 4 will be enough) to which you need to bolt the motherboard. There can be no problems with this procedure, since the main and only condition is to be able to use a screwdriver. Tighten the bolts tightly, but do not use excessive force to avoid breaking the motherboard. If the device is stably held in the case and not “ride”, that’s more than enough.

2. nutrition. The first step with regard to devices is to connect the power supply. Its installation on the case does not cause problems. As many of the remaining cables will connect to other devices besides the motherboard itself. This will provide unhindered access to the connection of other devices.

The power supply should be connected with a 24-pin connector (sometimes 20). It will NOT work to confuse it with other trains (it is the only one). This connector looks like this:

The power supply socket is usually found on the edge of the motherboard. It is impossible to confuse it. this is the only connector of this width for two rows. You will NOT be able to connect any other device there. When connecting, you should do it carefully, slightly pressing. until it clicks, so that the latches on the connector and the cable match. In the same way, the rest of the loops are fixed.

All other cables from the power supply are completely different from each other, so there will be NO questions about which cable is intended for which device. When in doubt, look for guides and symbols. Or use the documentation for the purchased power supply / motherboard.

3. Winchester. The cable from the hard drive is wide and not very. It all depends on the plug. There are two flavors: IDE and SATA.

The IDE cable looks like this:

The black connector (left) plugs into the hard drive, and the blue (right) plugs into the motherboard. This is how the place on the motherboard looks like, where you need to insert the IDE connector from the cable (blue connector, between the two black ones at the top and bottom).

As for the SATA cable, it is much smaller in size and is inserted into a connector labeled “SATA1”, “SATA3”, etc. The designations can be anything, but they always contain the SATA keyword. It all depends on the motherboard model.

The SATA connector on the “motherboard” looks like this:

This is just an example, since such connectors can be of different shapes (vertical, horizontal) and located in different parts of motherboards.

You also need to connect the connector from the power supply by taking the guiding elements. Usually, there are no problems with this. This completes the connection of the hard drive to the motherboard.

4. map. Connecting the card to the motherboard is NOT a complicated process at all, but with specific tricks that you need to know in order not to break the latches. Most motherboards have clips like these:

They are completely identical to the RAM retainer. But sometimes there are not entirely obvious fixators, which every user needs to know about the existence and principles of operation. Before connecting the card, carefully study the work of the clips. If necessary, disconnect (or connect if the clamps are mechanical) the device may cause problems.

The card slot itself is shown under the number 8:

The vertical blue connector is where the card is inserted. The piece protruding from the bottom is a standard retainer. It is impossible to make a mistake, since inserting the card with the wrong side will NOT work because of the guiding cut on the connector.

Next, an additional power supply is connected to the card (for the vast majority of modern models) in the form of a cable from the power supply. Often, this is a connector with 4 contacts, but there are also 2 wires with 2 contacts or 1 wire, but with 8 contacts. It all depends on the model and manufacturer of both the card and the power supply. At the end, from the outside of the system unit, a cable from the monitor is connected. the card is completely ready for use.

five. Case fans (coolers). To connect these devices, it is enough to fasten them with bolts in the proper places (selected individually or following the documentation) and connect to the motherboard:

  • CPU_FAN (CPU. central processing unit; FAN. fan). The socket is intended for connecting a cooler to the processor. DO NOT try to connect a 4-pin ribbon cable into it, if there are only 3 holes for them and vice versa, it is better to purchase a fan suitable for this connector. If connected incorrectly, the cooler can quickly burn out or stop working, and this threatens overheating and damage to the central processor. Which, by the way, is the most expensive device in a computer.
  • SYS_FAN (System fan). A slot is provided for all other fans in the chassis. Coolers for blowing and other cooling in the system unit should be connected to this type of connectors (the sequence does not matter, you can connect to any of them). Usually there are several such connectors, depending on the motherboard model (SYS_FAN1 / 2/3, etc.). All of them are signed on the “motherboard”, it will NOT be difficult to find.
  • card reader (Card reader. reading memory cards). The card reader is particularly easy to connect to the motherboard. It is enough to insert the plug of the wire into any USB socket (signed on the “motherboard” as F_USB1, USB1, etc.). The same applies to any other devices connected to this type of connector.
  • The connection of the card reader to the motherboard looks like this:

    Connecting the front panel to the motherboard

    There is a front panel on any case (system unit). Naturally, it must also be connected to the motherboard, otherwise the computer will NOT even be able to turn on. In addition, on the front panel there are such (or similar in purpose) computer control devices:

    • computer power supply (start / stop) button (POWER SW) (see how to connect the computer start button to the motherboard);
    • computer restart button (RESTART SW)
    • indicators of access to the hard drive (hard disk; H.D.D.LED or HD LED)
    • sound indicators (SPEAKER)
    • blinking light on the computer restart and power-on buttons (POWER LED /.)
    • USB ports.

    In some cases, the names on the plugs and cables may differ. Instead of POWER SW (power switch), it can be written PWRBTN (power button), and RESTART SW (reset) is indicated as RESET (reset). They are the same names, but manufacturers sometimes use synonymous English abbreviations. You need to search for matches not literally, but according to the semantic load: PW. POWER, RES. RESET, etc. All these are identical values ​​written in different words. The same can be found on the motherboard.

    The place on the motherboard where you need to connect these plugs looks like this:

    In addition to the naming scheme, there are also color coding identical to the colors on the plug. This procedure should not cause problems. The black crosses in the picture are “keys”. They are located both on the connector and on the cables, but they can have different shapes (depending on the manufacturer). It is worth connecting the key to the key, thus, there will be no mistake when connecting devices. If the designations are comments or are difficult to read, you can try to connect the wires with inscriptions “on yourself”. Also, the connector sometimes has side latches. They can also act as a reference point when connected.

    The cables from the USB ports are connected to the corresponding connectors. They can be named F_USB1, USB1, or just USB. The number of such connectors may vary from motherboard model, but often there are at least 2 of them.

    In the next section, the connection of the motherboard is examined in great detail, the meanings of the loops are explained and a lot of additional information is parsed.

    How to connect a second monitor in Windows 10

    Sometimes users are faced with the question of how to connect a second Windows 10 monitor for a stationary computer or an external, also a second monitor for a laptop. This is required for different purposes, for example, for showing slides to the “general public” or for extending the computer desktop to be able to work with a large number of simultaneously open windows.

    Connecting an external monitor to a laptop or computer in Windows 8, Win 7 and Win XP can be found HERE,

    Let’s consider how to connect a second monitor in Windows 10. But first, an external monitor (for a laptop) or a second monitor (for a computer) must be connected, physically connected to a computer or laptop, and only then set up its operation.

    For this, the computer usually has a second port for connecting a monitor. But laptops now usually have a VGA port so that you can immediately connect a monitor to it.

    In modern laptops, the HDMI port is more often used, but not all external monitors can be directly connected to it. Therefore, first let’s see how you can connect an external monitor to a laptop, and only then return to the question of how to set up an external (second monitor).

    Filling the Gaps. Expanding the Horizons! Computer literacy with Hope. Configuring Multiple Monitor Modes

    The settings “Multiple displays” are especially important, for which Fig. 11 shows all the Possible options:

    Consider 4 (four) options for two screens that are available in the Windows 10 operating system:

    • Duplicate these screens
    • Expand these screens
    • Show only 1
    • Show only 2

    Setting up a second external monitor connection in Windows 10

    That’s it, now the external monitor and audio speakers are connected to the laptop. You can turn on your laptop, turn on an external monitor, turn on speakers. Now let’s get down to the settings.

    After Windows boots up, nothing will change on the laptop screen, the external monitor will be blank, or there will be a glimpse of the inscription on it that It is not connected, that there is no signal, the speakers will be silent. This is because we have NOT configured anything yet.

    Let’s move on to setting up. To do this, on a free space on the Windows 10 desktop Right-click to bring up a menu. In this menu we select the option “Screen Options” (Fig. 8).

    The display settings window opens. To set up an external monitor, you need to switch to the second monitor, the monitor with number 2, as shown in Fig. nine.

    After choosing this particular monitor, the picture of the monitor with the number 2 will turn blue, and the picture of the main monitor with the number 1 inside will become gray. This means that everything below the monitor setting options are now assigned to the second, external monitor.

    Let’s consider what settings can be set for the second monitor:

    In the settings of the external (second) monitor (Fig. 10) you can set:

    1) brightness. by moving the lever to the left (weaker) or right (brighter),

    2) night light. by on / off switch,

    3) scale. in Fig. 10 shows that the scale is 100% (recommended), but it can be increased to make the image larger,

    4) resolution. in Fig. 10 shows that Windows 10 offers to set the default resolution, which is most often the best for an external monitor,

    5) orientation. as a rule, landscape orientation is set (with the long part horizontally), although in some cases the portrait orientation will also be useful (with the short part horizontally),

    6) simultaneous operation of multiple displays (see below).

    Setting up the screen on two monitors

    But I decided NOT to stop there. Then came the setting. This is where the first problem surfaced. Since the resolutions and diagonals in the screens are different, it will NOT work to fully combine them. So I had to adjust to the limitations.

    In Display Settings in Windows 10, you can select your main monitor. It is desirable for them to make the monitor on the left (fig. 9). Where the displays will be indicated, you need to drag the first one with the mouse so that it is to the left of the second. The convenience of such an arrangement shows itself when dragging elements and windows from one screen to another.

    The downside of using two monitors was that desktops, like taskbars, are not independent from each other. it’s just a very large desktop that allows you to work on one screen, and enable YouTube or something else on the other.

    My next steps were to try to set the screen resolution to the optimal proportional one. In my case, it was NOT successful, as the resolutions and aspect ratios of the screens were very different. It was decided to leave the screen resolution as it was.

    Then I moved on to the screen display options. There were only four of them:

    • duplication,
    • expansion,
    • display only on the first and
    • display only on the second.

    I chose the second option. expanding the screens, thus combining the two screens into one. But if necessary, at any time you can switch the display mode through the settings panel (the “Display” tab), so you can safely experiment with this function. You can also use the keyboard shortcut by using the keyboard shortcut Windows and P (English).

    3 Show on first screen only

    This possibility is highlighted by number 3 in Fig. 11. She speaks for herself:

    • the image will be displayed only on the main laptop screen,
    • or to the first screen of a desktop computer.

    The second monitor will NOT be involved.

    The meaning of this option when connecting a second external monitor is only to temporarily disable the display of the image on the second monitor, for example, if at the time of demonstrating the presentation, the speaker decided that he does not want to broadcast some part, show it to the general public.

    Or it can be used exclusively for settings, when you need to temporarily turn off the second external monitor, and again show the entire image only on the main screen of a laptop (stationary computer).

    Setting audio playback modes

    After connecting and setting up an external monitor, it remains for us to adjust only the sound so that it sounds “correctly” through the external speakers connected to the adapter.

    To do this, right-click on the speaker icon in the lower right corner of the taskbar. In the context menu that appears, select “Playback devices” (Fig. 12).

    Next, select the connection option where our external monitor is indicated. In this case, it is an Acer monitor, so we click on the line where this monitor is indicated (Fig. 13). It doesn’t matter that in this case we connect the sound, and not.

    And it is important to point out that the sound should be reproduced through the port where the external monitor is connected, since we connected the speaker connector to the HDMI-VGA adapter (Fig. 7), where we also connected an external monitor (Fig. 5).

    On this connection of the external (second) monitor and its settings in the Windows 10 system, in general, is completed. You can now use the second external monitor in accordance with the selected option for its connection and use.
