Good morning friends of the forum.
This laptop has the following problem. If I connect the battery cmos, (controlled and measure 3.20v) the machine runs and works well, if I try other times or detach the DC cable ,, or try only with the battery the machine does not turn on anymore. I have to disconnect the battery cmos and the notebook turns on. I tried to reprogram the bios (U8m1) and ME region (U4M1) with dumps found on the net but nothing to do.
How to continue?
