Why Does My Computer’s Power Button Not Work? – Possible Causes

There are a number of issues that might cause your power button to stop working properly. The problem might be simple enough for a sixth-grader to handle or complex enough to need the assistance of a professional.

Before you panic and do anything stupid, I propose that you try each of the methods listed below.

Check the Power Source Outlet

If your power switch isn’t functioning, it’s likely due to a problem with your outlet rather than anything else.

To test this notion, connect anything to your PC, such as a light or radio, and use their power button instead of yours. If you can switch these devices on with any of them, the issue is with your outlet.

Before you go on your computer and start troubleshooting, make sure your outlet is functioning properly. Also, if you’re using a stabilizer, make sure it’s giving your PC the right voltage. Also, instead of putting your computer on the carpet, consider putting it on a stand.

Examine the Power Cable

When a computer’s power button stops functioning, the first thing that springs to mind is the cord. There are several reasons why this one does not operate properly since it is plugged straight into your PC.

Unplug any wires that aren’t firmly attached or aren’t connected at all to your computer’s power supply unit and try again. If they no longer fit after being separated, something occurred to their physical shape, and you’ll require new components as soon as possible.

If the plugs seem to be good but you’re still having trouble, look for apparent damage such as cuts, rips, or loose insulation around the wire’s surface, as these might be blocking it from transferring signals back and forth between your case’s safety switch and the interior of your PC.

Use a different set of power cords that function nicely. You may test it on your PC by unplugging one power cord from your display (if accessible).

Is the power button on my computer broken? Check the power button pins and connections on your computer

Two little prongs on the back of the case link the PC power button to the motherboard. Unfortunately, these pins are quite fragile and may be shattered if they are stacked on top of them or if they are dropped accidentally.

To put this notion to the test, remove all of the things that were possibly blocking your PC’s power button connections. You may also test them by disconnecting and reconnecting them.

The cables from the power button are linked to the motherboard directly. If the wires are damaged, they must be replaced or rewired if they are still functional.

Cleaning the Power Button Is an Option

If none of the above ways work, your power button may need to be cleaned. To be done correctly, this complicated operation needs specific gear and professional know-how, thus I suggest delegating this work to a specialist if at all feasible.

Due to a pressing problem, your power button may not operate. If debris has gotten inside the power button, it must be cleaned out.

Follow these procedures in order until your computer’s power switch works again: Remove the side panels and unplug any cords from the rear panel of your computer case (if any).

Suck out the dust within your case using a pressurized air duster can or a vacuum cleaner with a tiny nozzle attachment, paying special attention to the areas where your safety switches are positioned on both sides. If they’re held together with screws, don’t remove them when cleaning since they’ll be required to put everything back together.

Remove any screws that don’t look like the others since they’re frequently utilized as placeholders rather than fastening things down firmly during an assembly at manufacturers’ factories.

Check Your Power Supply

The power supply unit (PSU) is the component of your computer that converts and regulates high-voltage alternating current (AC) energy into low-voltage direct current (DC) (AC).

You will need some electrical testing equipment to diagnose this component. Check the input AC voltage, which should be between 100 and 240 VAC, or whatever numbers your nation uses as a standard, to see if there are any problems.

You may also use a multimeter to check for any damaged components surrounding the output DC rails by placing the negative probe on one side of each rail segment and the positive probe on the other until you locate an area without resistance in between them.

You may also try disconnecting the PSU connection from your motherboard and reconnecting it. It would be beneficial to wait at least 30 seconds before reconnecting the connection to the motherboard.

If you suspect your Power Supply is causing the problem, borrow one from a friend to try.

A Different Motherboard Should Be Examined (If Applicable)

To see whether your main motherboard is the root of the problem, unmount everything from it and reinstall everything on your secondary motherboard. If it works, your motherboard has to be replaced.

Whether none of the above options worked, consider changing your motherboard as a final resort to see if it resolves your pc case power button not functioning problem. If this solution fails, consider purchasing a new computer because something may have gone wrong with its hardware, or there may be an actual short-circuit resulting in electrical damage that is beyond repair at home unless you know what you’re doing and how much money you should spend on computer repairs. As a result, I advise leaving everything to the pros.

Remove any newly installed hardware if possible.

If you’re not sure your motherboard is the root of the problem, try disconnecting and replugging any freshly installed components.

There might be a loose connection somewhere, or something could have been broken during installation, so double-check everything before proceeding, such as calling a professional for assistance.

Turn On The Computer Without Using The Power Button

If none of the above techniques work, try turning on the computer without pressing the power button to see if it starts up. To do so, press and hold the power button for five seconds before removing your finger to observe what occurs. Whether nothing works, try holding down the reset switch on the rear panel and checking again after a few minutes to see if it worked.

How to boot your PC without a power button should be documented in the motherboard’s handbook. The procedure for turning on the computer from the motherboard varies by model.

The conventional method of turning on the computer from the motherboard is as follows.

  • The power switch pins on the motherboard must first be located.
  • Once you’ve located them, use a conducting tool to connect the pins. Do this again when your computer is plugged in.
  • Your motherboard will get a signal to switch on the computer, and it will do so.
  • Touch those pins together again until the computer shuts down to turn it off.

If Nothing Works, Try Contacting An Expert

If none of the above ways work, something is amiss with your power button or motherboard. At that time, you should get assistance from an expert. Depending on how bad the issue is and if they can cure it or not, they will be able to remedy it by changing components or the complete PC.

Do not attempt to open up your computer unless you are sure in your ability to do so, since individuals often make errors while attempting to repair their computers without first learning how to replace certain components on a PC.

For example, motherboards aren’t worth fixing owing to the danger concerns linked with electrical devices having fewer components than ever before, so if you don’t want to be sorry later, leave everything to the specialists. They will assist you in resolving your computer’s power button issues.


A number of things might cause your Power Button to stop working. You may attempt to resolve this issue at home using the techniques outlined above. If none of these work, you’ll require expert assistance since your Power Button or Motherboard may be broken.

You must also ensure that the BIOS settings of the machine have not been tampered with. Users sometimes alter BIOS settings. However, doing so may create more harm than benefit.

Let’s say none of the approaches listed above work for you. In such a scenario, it’s essential to call a professional right away since they can simply and swiftly fix the issue without any fuss.
