The processor required to link the power button on the casing to the motherboard is not very complex. For this, you’ll need to consult your motherboard’s instruction manual.
A power button can only be connected directly to the motherboard if it is connected to the right set of pins (also known as terminals) on the board.
The “Front Panel Header” is a block on which several of these pins may be found. The front panel header includes pins for the Power Switch, Reset, Power LED, motherboard Speaker, and other functions. “
If you’re still stumped, don’t worry; the following text will walk you through the process of connecting the power button to the motherboard.
I recommend that you keep the definition of the following two term in mind for this article
Many different pins are used on a typical motherboard. Among these pins are those for USB ports, motherboard fans, and so forth. The SW PW or Power Switch pins are what we’re wanting for the power button.
The term “header” is used to describe motherboard connections that include many male pins. Pins on a header may be used for a variety of purposes.
On the Front Panel Header are the Power Switch pins.
Connecting the power button involves the following few simple steps
As mentioned earlier, the pins for the power switch can be found on the motherboard Front Panel Header.
You can locate the Front Panel Header by:
According to my motherboard’s instructions, the Front Panel Header may be found here.
Front Panel Header is positioned on the right side of the motherboard, according to this.
Physical examination might also help you locate the front panel header. There are labels on almost all of the headers indicating what they are there for.
When referring to the motherboard’s Front Panel Header, the term F Panel is often used.
There are many pins on a Front Panel Header for different purposes such as:
Once you’ve found the Front Panel Header, you’ll need to figure out which pins go with the Power On switch.
This means that there are always two power switch pins together.
The labels adjacent to the motherboard’s Front Panel Header are a great place to start when trying to figure out which pins to use.
The label for the Power On pins has been highlighted in the accompanying picture.
The power switch is located on the third and fourth pins from the left of the first row.
The following shows the power switch pins location for my motherboard:
Finally, connect the Power Switch jumper to the Front Panel Header’s Power Switch pins.
Jumper cables for a slew of additional functions are pre-attached to every PC casing, including the one that houses the Power Switch.
For a switch, the polarity of the 3rd pin in the first row does not important, despite the fact that the motherboard labels read +PW-.
The jumper may be connected in any direction, on any terminal, as long as the circuit is completed.
Make sure you connect the negative jumper in the negative pin and the positive jumper in the positive pin for LED lights for Hard Disk and Power.
In addition, there are a few alternative ways to get your motherboard to boot up. If your PC case’s power button or the jumper connection is broken, these ways may come in handy:
These are pretty straight forward to use.
As you would typically do, you connect the jumpers to the Power Switch pins on the Front Header Panel. On the other hand, there is a push button that functions in the same way as the one on the computer casing.
Additionally, bench testing your motherboard i.e. doing so outside of the case, might benefit much from this.
Do not use this if there is no power switch at all. The precise screw driver in your toolbox may serve as a jumper for your motherboard.
Using the screw driver, you’ll want to make contact with the two power switch pins on the panel header.
Here, the screwdriver should not come into contact with other pins. As a result, a precision or a tiny flat screwdriver should be used.
To get your motherboard up and running again, you can close the circuit on the two power pins in the Front Header Panel. Using a fine-tipped screwdriver, do this task.
Most motherboard do not come with a power button located on the motherboard. Instead, the only come with the Power Switch pins we discussed above.
However, on some premium motherboards, you may find a dedicated push button for powering it on.
Once you understand the Front Panel Header on your motherboard and its pin design, connecting a power button to your motherboard is a cinch.
Plug the Power Switch Jumper connection from your PC case onto those pins on the Front Panel Header that match to your computer’s power switch.
