I tried to pinpoint the problem. Here are my findings: When booting laptop with UltraBay battery inserted gnome-power-manager recognizes 2 batteries properly. It even supports hot-swapping. You can remove the UltraBay battery and plug-in dvd and it is fully recognized. After removing dvd from UltraBay and inserting UltraBay battery once more it is properly recognized by gnome-power-manager.
When booting laptop with with inserted UltraBay dvd and UltraBay battery removed gnome-power-manager does not recognize UltraBay battery when it is inserted later. Restarting gnome-power-manager doesn't solve a problem. The UltraBay battery is clearly visible through tp_smapi: cat /sys/devices/platform/smapi/BAT1/model always gives proper response when UltraBay battery is plugged-in I think it might be acpi problem since it recognizes batteries during boot: [ 16.860864] ACPI: Battery Slot [BAT0] (battery present) [ 16.900601] ACPI: Battery Slot [BAT1] (battery present) or only [ 18.071537] ACPI: Battery Slot [BAT0] (battery present) -- gnome-power-manager doesn't support thinkpad UltraBay batteries https://bugs.launchpad.net/bugs/280920 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
