hello,

i have this laptop and it seemsd to have some problem with the internal psu.
the problem is that as i plug in the ac adapter the dc red led lights on but if i try to turn it on, it starts flashing.
If somebody had the same problem, could giv esome hint?
does anyone have the possibility to disasemble it and tell me some voltage tension like on the battery pin (14,7 v for me)....... or the component he eventually replaced?

i tested bot mosfet and they seems ok
the cmos battery seems bad and i'm not shure it's original so if you have any picture or description of it....
all the caps seems good

so the suspects are on the hybrid circuits, the smd ic all aroud and the circuit with the two sensors for the battery (is there any way to disable them?)


thanks for the help and happy year

Domenico (Italy)
