If your computer is not turning on, or is having other problems, it’s likely that the power supply is the issue. To check if your power supply is the problem, follow these steps:

  1. Unplug all of your computer’s cables from the wall and plug them back in one at a time, starting with the power cord. If your computer still doesn’t turn on, try plugging in a different cable.
  2. If you’re using a desktop PC, remove the battery if it’s removable and try to turn on the computer again. If you’re using a laptop, remove all of the battery’s cells and try to turn on the laptop again.
  3. If you still can’t get your computer to turn on, contact an authorized technician or go to an electronics store to have it checked out. ..

Steps to Check Power Supply on PC

Shut down your computer completely. You can hit “Start,” “Power,” and then “Shut Down.” Once it’s off, unplug it.

Remove the computer’s side panel by gently pulling it away from the case. Some cases can be unclipped, while others will need you to grab the screwdriver and remove around two to eight screws.

Plug the power cord back in and turn on the computer. If it does not start up, check to see if the power supply is working by plugging it into another outlet and turning it on. ..

Final Words

If you’re not sure whether your power supply is working properly, it’s a good idea to check its DC voltage output. This can be done by using a digital multimeter to test the DC voltage output of the power supply. If the voltage is below the required level, then your power supply may be defective. If it’s above the required level, then your power supply may be working properly.
