Just installed Ubuntu on my laptop. What is weird is that my battery life has become shorter, and when I try to charge it, it said that my battery will be full in 8:30 hrs. While on my Windows, it only take less than 2 hrs make it full.

Please help

    If you have only just installed then you probably need to run ubuntu for a while, charging and discharging so that ubuntu can gather statistics about your battery life Nov 21, 2011 at 17:53
  • You seem to be comparing one program's estimate at the beginning of charging with another program's estimate. How long does it really take to charge? On your system, look at /var/log/pm*.log, and see if anything fails, look at the pm-utils package (dpkg -L pm-utils), and search AskUbuntu, see askubuntu.com/questions/400/…

  • You also need to make sure you have the latest updates. In terminal type: sudo apt-get update && sudo apt-get upgrade, or just use Update Manager.
