Hope you can help me, I'm new to ubuntu and install this 12.10 version on my acer laptop. The problem is I always got high temperature and maybe because my CPU fan is not working. Tried to install acerhdf but unfortunately it says unsupported bios. The temp I always got is 75 and higher and when I tried to open youtube or play any music and videos, my system restart. I also found out that this laptop doesn't support linux according to their site. So if you could help me it would be great, and if there is no solution to this then maybe I'll try other platform.
