When I start it, the fan works for a second and then shuts down. Then after a couple of minutes or seconds (it's shortening) the computer shuts off (at that moment the fan works again for a millisecond).
There's a print screen a second before it shuts off:



I already cleaned all components and also the thermal paste. Didn't work.

I tested the fan on another computer and it worked perfectly.

I should also say that I'm using a different charger (using: 20V 3.25A / original: 19V 3.42A). But the same happens when I'm using its battery, so I don't think this is the issue.

I appreciate your help.

As per the snap attached it shows that the GPU temp is very high which means that graphics releated chip is making some problem.
Due to this high temp. of GPU ur device is shutting off after few minutes.
I consider it is a motherboard problem releated to grpahics chip.
so it goes to chip level repairing.
if it's not in warranty better u get repaired from ur nearest shop.
