I worked on Windows 8 previosly and I never had problems: my laptop was quiet and battery life was about 5-6 hours without charge.
Then I installed Ubuntu 12.10 and my problems started: now fans are always on and have very strong noise and battery life shortened to 1-1.5 hour!
How can I solve this problem?
