I've recently installed 11.04 on a fresh Lenovo ThinkPad T410 with a 9-cell battery, but it totally drains up from full battery after about 2:30 - 3:00 hours of normal use (mainly web surfing).
The other problem is that brightness keys are detected, but not working. when I increase/decrease brightness, the notification appears (and it shows that it's been increased/decreased) but nothing changes.
How can I resolve this issue? Is there a human-friendly solution? Is there any plans to solve this problem out-of-the-box in next releases?
