Wont shutdown

[AnaBadon]

I shut down the laptop using the shutdown button, but only the display went out. The light on the power button is still on, and it has been 2 hours since. The laptop's fan is also on, its like it didnt shutdown completely but I cannot do anything about it! I cant see anything on the monitor.

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures.

I had the same problem after updating all the drivers of the laptop. I found the latest Realtek audio driver was causing this issue. Rolling back to the previous version solved it for me.

Hope this helps!
