Public bug reported: The battery life tool is incorrectly predicting the life of the battery in Ubuntu 11.10.
This causes an unwanted shutdown when the laptop has plenty of power left. It has done this immediately after pulling the power out of the back of the laptop - My battery is not faulty. Some info about my system: root@Lenovo:~# cat /proc/acpi/battery/BAT1/info present: yes design capacity: 5100 mAh last full capacity: 5100 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 420 mAh design capacity low: 156 mAh cycle count: 0 capacity granularity 1: 264 mAh capacity granularity 2: 3780 mAh model number: PA3465U serial number: 3658Q battery type: Li-Ion OEM info: COMPAL root@Lenovo:~# cat /proc/acpi/battery/BAT1/state present: yes capacity state: ok charging state: discharging present rate: 0 mA remaining capacity: 2703 mAh present voltage: 11100 mV root@Lenovo:~# cat /proc/acpi/battery/BAT1/alarm alarm: unsupported I am unsure whether this is helpful.
