Since my upgrade to Ubuntu 7.10 my notebook’s battery life went considerably down. In my post Battery life of FSC Amilo si1520: Windows Vista vs. Ubuntu 7.04 I was mentioning a battery life of about 3:00 hours in normal conditions on my FSC Amilo si1520, with a dimmed screen and wifi off it was even possible to go up to 4:00 hours.
Now, after installing Ubuntu 7.10 the battery live in normal conditions is just below 2 hours (1:50h). Did anyone have the same problems? Any solutions?
Intel offered a little software to improve battery life on notebooks running Linux. The tricks are helping a little bit, but how can I make the changes permanent? Ideally you have experience with the Amilo si1520, but any tip will help, I guess.
