PC Pavilion All-in-One Desktop will NOT shut off

[Sig-Pig]

Tried everything …

 - Fresh Start Windows 10

 - Re-configured Power Settings & 'what the power buttons do'

 - Disabled 'Fast Boot', etc.

 - Updated BIOS

Followed just about every boot / shut-down diagnostic on YouTube and Reddit thread ...

PC will shut-down, but will not turn off … you can hear the fan still running and the power light is still on.  You need to press and hold the power switch to finally kill the juice.

Also, when I elect hibernate … it goes to sleep but will not wake up … I need to kill the power and restart.  So, I disabled hibernate.

Please help.

Greetings,

Welcome to the forum.

I am not a HP employee.

You have a possible problem with:

Power switch,

Power Supply,

Motherboard.

You may need to check all component connections and cable connections to the motherboard.

A faulty peripheral device could cause weird PC behavior.

You have to troubleshoot each part.

Look, I usually check the CR 2032 MB battery with a tester or replace the battery. This is a cheap troubleshooting step.

Hi, @Sig-Pig 

The only suggestion I can offer would be to install the latest version of the Intel Management Engine Interface driver on your PC's support page, and restart the PC.
