Why Computer Power Button Is Not Working? – Possible Issues

There are more than a few factors that contribute to your power button failing to function correctly. The issue can be easy enough to solve by a 6th grader or hard enough to consult an expert.

Before you start panicking and do something wrong, I recommend trying every method explained below.

Check The Source Power Outlet

If the power switch isn’t working, there’s a good chance it is related to an issue with your outlet and not anything else.

Plug something into your PC like a lamp or radio and use their power button instead of yours to test this theory out. If you can turn on these things by using either one of them, then the problem is with your outlet.

Make sure your outlet is working fine before you jump onto your PC and start troubleshooting. In addition, if you are using a stabilizer, ensure that it provides proper voltage to your PC. Also try to put your PC on stand other then on carpet.

Check Power Cable

The cable is the first thing that comes to mind when you think of a power button on pc not working. Since this one goes directly into your machine, there are many reasons why it doesn’t work correctly.

Check if any cables aren’t connected tightly enough or at all to your computer’s power supply unit by unplugging them and trying again. If they don’t fit anymore after being disconnected, something might have happened to their physical form, so you’ll need replacement parts ASAP.

If everything seems fine with the plugs but still no luck here, try checking the wire itself for visible damage like cuts, tears, or loose insulation around its surface because these could be preventing it from sending signals back and forth between your safety switch on your case and inside of your PC.

Try using another pair of power cables that work well. You can unplug one power cable from your monitor (if available) and try it on your PC just for testing.

Is my PC power button broken? Check PC’s Power Button Pins and Connection

The PC power button is connected to the motherboard through two small prongs located on your case. Unfortunately, these pins are very delicate and can be broken if you stack anything on top of them or accidentally drop something heavy without noticing it.

To test this theory, try taking off all of these objects that might have been standing above where your PC’s power button wires. You can also disconnect and connect them again to see if they work.

The wires coming from the power button are connected directly to the motherboard. If the wires are broken, you need to replace them or rewire them if they can still work.

Try Cleaning The Power Button

If none of the previous methods work, you might need to clean your power button. This complex process requires special tools and professional know-how to be done right, so I recommend leaving this task up to an expert if possible.

Your power button might not be working due to its pressing issue. If the debris found its way into the power button, you need to clean it off.

Go through these steps one by one until your PC’s power switch starts working again: Unplug all cables from the back panel of your computer case and remove its side panels (if any).

Compressed Air Duster Can

Use a compressed air duster can or vacuum cleaner with a small nozzle attachment to suck out the dust inside of your case, including around where your safety switches are located on both sides. If there are screws in keeping them in place, then ensure not to take them off during cleaning because they are needed to put everything back together.

Take out all screws that might look different from other ones around them because they’re usually used as placeholders instead of holding things down securely during an assembly at manufacturers’ plants.

Test Your Power Supply Unit

The power supply unit (PSU) is the part of your PC that’s responsible for converting and regulating low-voltage direct current (DC) electricity from a high voltage alternating current (AC).

To troubleshoot this component, you need to have some electronic testing equipment at hand. First, find out if there are any issues with it by checking its input AC voltage which should be between 100 VAC and 240 VAC, or whatever numbers your country uses as their standard.

You can also check any broken parts around the output DC rails using a multimeter where you’ll put its negative probe on one side of each rail section and positive ones on another until finding an area without resistance in between them.

A Power Supply Unit

You can also find out whether your PSU is working by a simple troubleshooting method. First, remove the side panels from your system and connect them with power. If your PSU is working, tiny LED lights present on the motherboard (if any) will light up. If they light up, it signals that your PSU is working fine and providing power to your motherboard.

You can also try unplugging the PSU connector from your motherboard and try plugging it back again. It would help if you waited at least 30 seconds before plugging the connector back on the motherboard.

If you think your Power Supply is the source of this issue, you can borrow one from your friend to test.

Check On A Different Motherboard (If Applicable)

Unmount everything from your main motherboard and mount them on your other motherboard to test whether the motherboard is the primary source of the issue. If it works then, you need to replace your motherboard.

A Motherboard

If all the above solutions didn’t work, try replacing your motherboard as a last-ditch effort and see if that fixes your pc case power button not working issue. If this solution doesn’t work either, consider getting a new computer because something might have gone wrong with its hardware, or there could be an actual short-circuit resulting in some electrical damage that is beyond repair at home unless you know what you’re doing and how much money should you put into fixing such problems on computers. Hence, I recommend leaving everything up to professionals instead.

You can also contact an expert to ask for help. They might help you solve this problem.

Try Removing Any Newly Installed Hardware

If you think your motherboard is not the source of this issue, try unplugging all newly installed hardware and plugging them back in again.

There could be a loose connection somewhere, or something might have been damaged during installation, so make sure to check everything before taking further steps, such as contacting an expert for help.

Manually Turn On The Computer Without Power Button

If none of the above methods work, manually turn on the computer without the power button to see if it boots up. To do this, press the power button for five seconds, then take your finger off it to see if anything happens. If nothing does, then try holding down the reset switch on the back panel instead and check again after a couple of minutes have passed by to see if that worked or not.

A manual provided with the motherboard should show how to boot your PC without a power button. The process to turn on the computer from motherboard may differ from model to model.

However, the following is the standard way to turn on the computer from the motherboard.

  1. First, you have to locate the power switch pins on the motherboard.
  2. Once you find them, use a conducting tool to touch those pins together. Again, do this while your PC is connected to the power.
  3. Your motherboard will receive a signal to boot up the PC, and your PC will turn on.
  4. You can Turn off the computer by touching those pins together again until it shutsdown.

If Nothing Works, Try Contacting An Expert

If none of the above methods work, then your power button or motherboard might have gone wrong. You need to contact an expert for help at that point. They will be able to solve this problem by either replacing the parts or the entire PC itself, depending upon how severe it is and whether they can fix it or not.

Don’t try opening up your computer yourself unless you are confident about doing something like that because people make mistakes all the time when trying to repair their computers themselves without knowing what they’re supposed to do to replace specific components on a PC.

For example, like motherboards, but anyway, buy another one because repairing them isn’t worth it due to risk factors involved with electronic devices having smaller components than ever before, so if you don’t want to be sorry later on, then leave everything up to professionals. They will help solve your pc power button not working properly.


Several factors can cause your Power Button not to work. You can try to fix this problem at home by following the methods described above. However, if none of them work, you will need help from a professional as your Power Button or Motherboard might have gone wrong.

You also have to make sure that you haven’t messed with the system’s BIOS settings. Sometimes, users change BIOS settings. But doing so can cause more trouble than good.

Suppose the methods described above don’t work for you. In that case, it’s best if you contact a professional immediately because they can repair this problem easily and quickly without any hassle at all.
