![]() Connect the power button to the motherboard How to connect the Power button to the motherboard?.You may have also learned more tricks about starting your laptop without connecting the power button. Now you know how to connect the power button of your computer case to your computer’s motherboard and some of the everyday things to look out for. If you cannot jumpstart with a screwdriver, you may need to purchase a new motherboard with the power button terminal intact. If you can jumpstart your computer using a screwdriver, but the cable isn’t working, it is a problem with your cable. If, once you have put everything together, the power button does not work, check to ensure you have installed the jumper switch to the correct terminal and installed before checking other options. You must make sure you do not touch any of the other pins, so use the smallest screwdriver possible. You do this by touching the screwdriver to the power pins in the Front Header Panel. If you are trying to jump-start your motherboard and lack standalone power switch cables, you can start your motherboard using a small flathead screwdriver. These cables can also come in handy when you are testing the motherboard outside of the case and have not reached a point where you are connecting the case power button to the Front Header Panel yet. You connect one end to the Front Header Panel, and the other end gets wired out of your case with a push-button for you to turn on your computer. If the jumper cable is damaged and you cannot replace it for whatever reason, you can get standalone power switch cables separately. Polarity does matter for LED lights, so when you connect those jumper cables, you will have to pay attention otherwise, they won’t work correctly. The jumper can be connected either way so long as it fits completely to complete the circuit. When Polarity MattersĪs a side note, while the motherboard does have polarity (+/-) labeled, the positive and negative sides do not matter for a switch. ![]() While many motherboards can fit in a case, each case has different dimensions and locations to mount the motherboard. The jumper cable comes with the PC case rather than the motherboard. Now that you’ve located the correct terminal, you need to connect the jumper to the pins. The reset switch button probably looks very similar, but it will be labeled RESET SW or some permutation. The power button terminal should be labeled as SW_PW or POWER SW, to delineate the Power Switch. ![]() There will be a diagram on the motherboard labeling each header’s purpose. Thankfully, the worst that happens when you plug the cable into the wrong terminal is that it doesn’t work correctly, as opposed to frying something. Given that the header contains pairs of pins for many purposes, you will have to inspect further to find the right pair. Once you have located the Front Panel Header, you need to determine which pins are for the power button. The 20- or 24-pin terminal you see is for the power supply, not the power button. The Front Header Panel is an 8-pin terminal, meaning there are 4 pairs of 2 pins. The Front Panel Header is usually labeled F_Panel. If finding the header by sight is not easy, you can also reference the manual that came with the motherboard, which will have a diagram in it showing you the location of the front panel header. ![]() The terminals are usually a pair of pins located on a black called “Front Panel Header.” The Front Panel Header contains the pins for the power switch, the reset button, the audio jack, and the status LED lights. The first step is to locate the correct terminals on the motherboard intended for a power switch. Here are the steps to connect a power button to a motherboard. ![]() After this, you repair the existing power button, or you connect a new one to the motherboard. Once you locate the power button terminal, you can troubleshoot the circuit connection and diagnose the problem. The main issue faced when repairing the PC power issues involves locating the power button circuit terminal in the motherboard.
