Hi Tuomas, it seems that your broken battery is coincidence. I reported this problem a while ago: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/889942
And it is still present in 12.04. My Laptop ran Hardy for years without this issue and I upgraded straight to 11.10, so it might also be with earlyer releases. But the kernel goes to: $ cat /sys/class/power_supply/BAT1/voltage_now 14791000 $ cat /sys/class/power_supply/BAT1/current_now cat: /sys/class/power_supply/BAT1/current_now: Kein passendes Gerät gefunden $ cat /sys/class/power_supply/BAT1/voltage_now 10000000 minutes after reboot and I'm pretty shure Hardy's wouldn't, as also the other OS shows the battery just fine. The voltage_now value above is wrong, the panel showed a 100% battery whereas it was around 50% judged from runtime and the seemingly correct print with win. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987460 Title: battery indicator does not show battery remaining To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/987460/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
