Hey there! @tom_yon_15, Thanks for stopping by the HP Support Forums!


I understand you have issues powering on your PC.


Don't worry I'd like to help you out.


Did you make any hardware or software changes on your PC?


Have you tried checking with a different adapter?


Do you see a light on the power supply?


Are you able to boot into BIOS?


Please provide the product number of your PC to assist you better.


Try plugging the adapter into a different wall outlet and check if it helps.


Try the steps recommended below.


If you still have no power, perform the following steps until power is restored or it is determined that there is a hardware failure:

   note:

If the power supply fan spins when the computer is turned on but the light does not turn on, see Power supply light comes on or flashes.

1. Disconnect everything from the computer, including the power cord.

2. With the power cord disconnected, press the power button on the front of the computer.

3. Plug in the power cord to see if the computer automatically turns on. If the computer does not turn on, continue using these steps.

4. Swap the computer's power cord with the monitor's power cord, and then test to see if the computer can turn on.

5.Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.

6. Plug a working electronic device into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.


7. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.


8. If all of the above steps have been tried and the power supply light remains off, use the steps in the next section.


If you are able to boot into BIOS try to restore the BIOS to default.


1.    Turn off the computer and wait five seconds.
2.    Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3.    On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4.    Press F10 to Save and Exit.
5.    Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6.    Follow the prompts to restart your computer.
