First of all, i thank all of youi , for helping where possible.
I cvan say, that i solved the problem.
I have gone further with de-asambling the laptop ( and NO, i did NOT find any help on internet, for the laser laptop is TO unknown...) and YES i DO know my stuf on electronica, pc's etc.
I have found the battery at the other side of the motherboard, took it out (carefully), and reasamble the laptop together.
it worked, and i'm ready to go.
So, thanks a lot, this thread can be shut.
