the laptop is still apart, had little time to experiment, the two
fuses are ok will have to test capacitors, in the while I took away
the cmos battery and soldered two wires to use a standard cr2032 but
nothing changes


my idea now, is that if I am not able to find the faulty component,
that may well be a custom one, I will try to cut the connections to
the battery poles and connect using a 2-way deviator, so that in one
position the lapton can work like now, charging the battery when
switched off, or running on battery only, or trun the deviator/switch
and give voltage directly to the cutted terminals, excluding the
battery, with an external power supply, the pc should still detect the
battery charge level from other contacts of battery in place

should this work?
