Hi,
Since a few months I dweld myself into some light laptop repairs, mainly reballing and now I also tried out some bios flashings. Btw, I work in at an IT sale store hence the need to try and repair these units. There is still a lot for me to learn, still need to catch the magic of reading laptop schematics.
My first question for today is: Why do some laptops start on their own the moment when ac adapter is conected to them. I noticed this at quite a few laptops and can't figure out quite why?
Any ideas where to look for troubles?
Simptoms for these troubles vary from laptop to laptop:
- laptop starts up on ac adapter conect but no vga,
- starts up on ac adapter with vga and performs well and can be shutdown
and a few other examples but I dont want to bring up that many examples.
