My HP Probook 450 G5 keeps turning on by itself after I shut the laptop down.

My laptop keeps turning on by itself every time I shut it down (after ~30 seconds).

I disabled the Wake on LAN option, the Wake on Mouse and Keyboard option, the Allow Wake Timers option, but the problem still remains.

I also updated my Windows 10 to the May 2019 update, but that didn't solve it.

I'm frustrated and out of options to do, so I had to come here and ask for a solution. Please help.

Thank you.

Hi

I would ensure that Fast Start Up is disabled.

Also I would try a Safe Boot and use shutdown, even using the command line shutdown.exe command. 

Safe Boot into Command Line only, eliminating the loading of potentially problematic drivers.

Why?

Because it may be a problem driver.

Fast Start Up and Automatic restart are disabled, problem remains.

I haven't tried the Safe Boot option still (actually I don't know how to do it...)

PS, Putting my laptop on Sleep works, I'm using that option until I solve the problem.

So, I found out that when I put my laptop to charge and shut it down, it won't turn on by itself.

But as soon as it reached 100%, it turned on again.

The laptop was at 14% when I plugged in the charger.
