Hi @mgalbert17 ,

As I understand, your All-in-one pc not powering on correct?

If yes, let's follow these steps. 

Remove discs and devices and perform a hard reset

To determine whether you need to contact HP or troubleshoot startup issues, perform a hard reset.

Note: A hard reset does not affect data saved on your computer.

• Turn off the computer.
• Disconnect the AC adapter.
• Remove any discs from the disc drive.
• Remove memory cards from the card reader slot.
• Disconnect all nonessential devices such as printers, scanners, external hard drives, and USB flash drives.

Note: Do not disconnect your mouse, keyboard, or monitor.

• With the AC adapter unplugged, press and hold the power button for approximately 15 seconds.
• Reconnect the AC adapter, and then turn on the computer.

Note: Be sure that you use the AC adapter that was shipped with the computer
