I installed almost 15 different distros of linux and all they have the same issues: overheating and high power consume.
AMD Turion II P560
HD 7200 rpm
Dedicated graphic card: 6370m
Onboard graphic card: 4250m
Idle temperature on Windows: 45ºC
Idle temperature on every linux distro: 62ºC
Battery Windows (using 4250m video card): 2:45 hours
Battery Linux (using 4250m video card): 1:20 hours
I need linux for study, but i tried too much distros and had this issue.
My actual distro is Ubuntu 12.10. I installed the AMD driver to controll the video cards but nothing change on temperature or battery...
As the windows, the ubuntu 12.10 also change the clock at idle, from 2.5Ghz to 0.8Ghz to power save, but still hot and the battery duration never goes more than 1:20 hours.
Someone can help me?
