I hate to go back to it, but you still saw nothing abnormal in the Event Viewer Logs leading up to the kernel power critical entry?

No if I look at it now it even says there hasn't been a critical event in the past 7 days...

Any specific log I should dive into?
Critical/Error/Warning/Information/Verification succeeded
(Not sure if I provided the correct translations)

Event Viewer > Windows Logs > System

 

If that's all normal, then it's a hardware issue?  Have you checked the CPU's temperature?

Currently I can't get into the PC as I had to shut it down due to not being able to login anymore in the Windows lockscreen. Trying to boot it into recovery but the BIOS menu doesn't show when I'm pressing it.

Waiting for that lucky shot...

I fear it has something to do with the power/battery. I can only boot the laptop when the battery is almost completely empty. Just did a full reinstallation of Windows and while rebooting for updates went fine, as soon as I did a full reboot the problem came back.

 

Edit: changed the boot order in the bios but didn't make any difference. Raising my concern regarding the battery/power. Will disconnect the battery later today and reconnect to see if that does anything, otherwise I'll have to get a new one I fear.

It sounds like more like battery or battery connection issue. Removing the battery could help

There should be an information within the User Manual or/and on the AC adaptor.

Should be alright.

I took out the battery and reconnected it: no result
Booted laptop without battery: no result
Booted laptop without RAM: no result

Fan doesn't start when starting as well... So I think it might be the motherboard.

Furthermore I found out that I have a "Dummy fan" on one side...

I don't think we would be able to help you after this point due to you would probably need a replacement - considering that mainboard would cost approx 2/3rd of the system, you may not have lots of options
