I have the same/similar problem with a Lenovo T420s running 12.04. The second battery is not recognized, and the laptop shuts down when the first battery runs out.
I do not have this problem on the same hardware with 11.10 (which is still installed). $ ls /proc/acpi/battery/ BAT0 BAT1 $ find /sys/devices/ | grep 'BAT[0-9]$' /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:09/PNP0C09:00/PNP0C0A:00/power_supply/BAT0 I'm not really sure what other information is pertinent...? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995034 Title: Second battery not found by acpi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/995034/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
