Probook 650 G2 not shutting down

[mk8489276]

Hi all, I have an HP ProBook 650 G2 laptop that is experiencing several peculiar issues.

Issue number one: Both the Wi-Fi switch and Audio Mute switch lights remain illuminated even when the laptop has been shut down. The Wi-Fi status light also remains illuminated.

Issue number two: When shut down, the battery drains completely within a few hours.

Issue number three: After making changes in the BIOS, saving those changes, and rebooting the laptop, I am greeted with a black screen, though I can hear the fan spinning. Only way to proceed with booting is turning the laptop off by holding the power button for a few seconds.

It appears the laptop is not shutting down properly. Already disabled fast boot and tested with enabling/disabling various power features in the BIOS.

Any ideas on what might be causing these issues? I've already tried different RAM, a different SSD, operating without the battery, and reinstalled Windows along with all required drivers. The BIOS has also been updated to the most recent version, I also tried older BIOS versions, without any luck.

Any help would be greatly appreciated.

"When shut down, the battery drains completely within a few hours"

That would seem to indicate that the laptop is not shutting down completely.

Try the following:

Create a shutdown shortcut for the desktop.

Right-click an empty space on the desktop and select new>shortcut.

In the dialogue that pops up  type in shutdown /s /t 0 and then select next.

Give your shortcut, such as Windows shutdown and then select finish.

the shortcut will appear on your desktop. 

You can click on it to instantly shutdown your PC.

You can right-click on your new shortcut to make changes, such as choosing an icon that you will remember.
