Hello, I have a big problem, my ASUS F5M notebook hangs when it is running on battery. Most of hangs are when the battery is under 50%. But it does not occur when it runs in Safe mode or in bios, dos etc. I found one guy, who had the same problem, and he reinstalled windows and it was OK, but I reinstalled Windows, it looks fine, but after I install bunch of updates from windows updates, the problem was back. So it could be because of updates, but it is not sure. Can you help me, please? Thanks
