Good afternoon!
I fell into the hands of a dns W271ESQ laptop with a startup problem.
When connected to the power supply, the motherboard does not react (the indicators do not light up), when the power button is pressed, the reaction is zero.
I assume that there was overheating. the radiator grill has a fragile structure.
Questions:
What could be the problem?
Burnt motherboard or processor?
How is it possible to check if there is no donor?

First you need to find out if the power supply itself is working; if yes, you need to look at the power socket in the laptop. If everything is normal, then the problem is in the power controller.

Quite often I came across (at least on old laptops) that when the batteries on laptops die, they cannot turn on. It helped to stupidly pull out (if it is of course removable) the battery and connect the power directly.
