Screen won't turn on, HP All In One C020

[Tayler1]

Power went out yesterday for a short while (less than 5 minutes) came back on and computer screen hasn't come on since the outage. Have tried unplugging the computer (and everything else that was connected to it) nothing has worked 😡

@Tayler1 Welcome to the HP Support Forum!

I understand that you are unable to see anything on the screen after the power outage.

Step 1: We will first perform a hard reset.          

• Turn off the computer.
• Disconnect power supply and all external peripheral devices.
• Press and hold down the Power button for about 15 seconds to drain any residual electrical charge

Step 2: Connect the power supply and turn on the PC and see if fixes the issue.

Step 3: Secondly, check if the brick on the power supply is getting warm.

Step 4: If it is not then it could be a power supply issue because of which the PC is not powering on.

Let me know how it goes and we can take it forward from there.
