I've been having some problems with booting lately
The symptoms are:
1- When I press the power button to start the laptop, the button lights up for about a second and then it turns off.
2- Sometimes I get "CMOS checksum is invalid CMOS Reset (502)", I restart then everything is normal
3- Sometimes Windows clock goes back in time suddenly when the device is on (logs say it synced to hardware clock)
My analysis:
I found that the BIOS clock is not updating, unless a specific area near the charging port is pressed hard
Also the laptop will not turn on unless this same area is pressed. I will attach a photo showing the area
My question is what could be the issue? btw my laptop fell on that side a year ago, but this booting & bios clock issue started happening quite recently

If there is no obvious physical damaged, but it requires being pressed down to operate normally, there is a broken or loose connection.
I suggest reseating all connections near where you put the cardboard.
If that do not resolve the issue, it means that the system board is damaged. That would require a system board replacement.
If something fails and inside the laptop. the carboard you put in there catches fire and there is an investigation, an insurance company would consider you at fault and not pay out a claim.
It is an unsafe workaround. I would not call that a repair.

Update:
It turned out that the problem was a loose motherboard, when the motherboard is pressed BIOS clock works again and booting & shutting down work fine.
As a temporary solution, I cut a piece of a carton box and inserted it in a seemingly safe area, hence when the cover presses against the motherboard because of the piece and it works just fine

That is an unsafe workaround.
Using a flammable material instead of replacing the damaged motherboard is not the best of plans.

I would not call the motherboard damaged. Motherboard screwed securely, however, for some reason it needs to be pressed down slightly. Here's a picture of my workaround. Is it actually not safe? what do you recommend in my situation?
