Remove The Case Panel
Before accessing the motherboard, you must remove the case panel covering it. Usually, this involves using a screwdriver to remove a few screws.
Locate The Motherboard
Upon removing the panel, the motherboard should become visible. It is a large, flat circuit board with many connectors and components.

Locate The Front Panel Header
After locating the motherboard, the next task is to find the front panel on the motherboard. There are two ways to find the front panel. Let’s discuss both of them one by one:
-
Using The Motherboards User Manual
To locate the front header on the motherboard using the motherboard’s user manual, you’ll need to follow these steps:
- Find the motherboard’s user manual. To find the motherboard’s user manual, you can look for it in the materials that came with the motherboard when you purchased it, or you can search for it online by using the make and model of your motherboard as a reference.
- Look for the manual section that covers the motherboard’s layout and connections. This section should include a motherboard diagram with all the various connectors and components labelled.
- Look for the label “front header” or “front panel header.” This should be a small group of connectors near the motherboard’s front. The front panel connectors are often labelled with abbreviations such as “PWR,” “RESET,” “HDD LED,” and so on.
-
Manually Searching For Front Panel Header
If you do not have the motherboard’s user manual and need to locate the front header on the motherboard manually, you can try the following steps:
-
To start, you can try to identify the front of the motherboard. This is usually the side of the motherboard that faces the inside of the computer case and is closest to the front panel connectors (e.g., power button, USB ports, audio jacks) on the case.
- Look for a small group of connectors near the motherboard’s front. The front header will often be labelled with a series of abbreviations such as “PWR,” “RESET,” “HDD LED,” and so on. It may also be labelled as the “front panel header” or “front header.”
- If you have difficulty finding the front header, look for the connectors connecting to the front panel buttons and indicators on your computer case. These may include the power button, reset button, hard drive activity LED, etc.
- Once you have located the front header, you can use the labels on the front panel cables from your case to determine which connectors they should be connected to on the motherboard. When connecting the cables to the motherboard, make sure to align the labels on the cables with the matching connectors on the motherboard.

Identify The Power Switch Pins
To identify the power switch pins on the motherboard’s front panel header, you will need to follow these steps:
- Refer to the motherboard manual or the manufacturer’s website to determine the pinout of the front panel header. The manual or website should provide a diagram or table showing which pins correspond to functions, such as the power switch, the reset switch, and the power LED.
The power switch connects to the motherboard via the power switch pins. - You can search for the front panel header on the motherboard to locate the power switch pins. They are usually labelled “PWR_SW” or similar. The power switch pins usually have positive and negative sides. The longer pin is typically the positive or “power” pin, while the shorter pin is the negative or “ground” pin.
Verify The Pin Layout
Different motherboards have different pin layouts, so it is essential to verify that the power button cable you are using is compatible with the power switch pins on your motherboard.
You can check the pin layout in the motherboard manual or by using a multimeter to test the continuity of the pins.
