I have trouble with battery life on ubuntu 12.10
Before I installed ubuntu 12.10, ı was user of ubuntu 12.04 LTS.
My computer is HP Probook 4530s. On 12.10 my battery life is less than 1.5 hours but on 12.04 my battery life is 2.30 - 3.00 hours.
Actually, İt sounds me crazy because sometimes i had to use my laptop portable without ac power.
Could anyone suggest anything about my problem?
