2011-04-09 Thread Dweia
Sorry, I got sidetracked while getting a set of logs. However, some (yet slightly vague) findings may be useful - even if debugging gets maybe even harder: Firstly: the computer (BIOS or whatever) behaves differently when external power is connected or only battery used, and secondly: it behaves d
