Hello!

In the thread title you stated that there is no picture, but in the post that the laptop does not turn on at all. Please, specify the accurate description of the fault.
Also specify the motherboard revision number.

Podłączasz oryginalny zasilacz czy serwisowy?

Your resistance measurements on the coils from post #6 seem strange.
Disconnect the power supply and main battery, wait about two minutes for allow the capacitors to discharge, and then check the resistances again.
