Hello, since I'm experiencing low battery performances coming from win 7 to Linux mint 14 mate, I'm trying to sort out the problem. With powertop the consumption while running only firefox is 27-32 watt. Closing firefox, switching off wireless and putting brightness at minimum I still have 22 Watt, while I read in internet that for my laptop you can go as low as 7 Watt in WIndows.
I have an acer 3820tg, and "apparently" already switched off the ati card with this method

But I'm not sure it's working, since the battery is draining very quickly. How to verify that the card is off?
Other suggestions apart from that to improve battery performances?

Maybe installing "laptop-mode-tools" will help reduce power consumption. Although 22 watts seems like a lot power. Are you able to see what is running and using the most CPU time?

Perhaps trying MATE might also reduce your power consumption. The video card on that device alone will pull 20 Watts.

Yep was my first thought also video driver used? And fans being on taxed 100% all the time.

Attached the list of powertop for the current consumption, with laptop mode tools installed.

I'm using the "standard" graphic drivers, and didn't touch anything for the fan behaviour
