I got the replacement battery by 12 today..Dell service is really impressive..New battery capacity is showing 91% in Ubuntu..i dont understand why it's not 100%

well congratulations. i feel bad that i did not ask for a replacement before september 20

checked again..capacity is 96% now..

the laptop's shud be smart, once batteries are fully charged it shud stop charging completely (but still use AC current). charging shud restart again only when it reaches say 5-10% of capacity. or if user wants, user can force a recharge.

I have noticed something new with Ubuntu 8.10...On 8.04 I was getting max battery backup of 1:45 Hrs but with Intrepid Ibex I'm getting a cool 2:45 Hrs!!! Battery is more than 15 months old! (But still has capacity of 95%, has been used for at least 150 recharge cycles, Seems Acer ain't that bad!) So have they done some major improvements in power usage?Anyway whatsoever may be the reason but I'm simply loving it..:yahoo:

well..check out if processor speed is not down clocked to get better battery life?

Hmmm I have opted for "On Demand" CPU usage...for Web surfing/Music/Office, processor uses lowest frequency. Same settings were there for 8.04...But there is definite improvement in battery management for sure. It reduces power consumption to 12.5 Watts/hr:yahoo:
I don't think even Vista has this feature. You need to manually choose wheter you want Max power usage or power saver option, there is nothing like On Demand usage. Whenever I do any heavy stuffs CPU usage goes to max automatically on Ubuntu!
