I see this too with version 2.24.0-0ubuntu8 of G.P.M, on a Packard Bell EasyNote A8202 laptop. In fact, it's been like this ever since I moved from Feisty to Hardy!
Example: tooltip shows "85.9%". The context menu says "51.0%" "lshal |grep -i battery" shows this: ----- battery.charge_level.current = 25070 (0x61ee) (int) battery.charge_level.design = 48840 (0xbec8) (int) battery.charge_level.last_full = 29190 (0x7206) (int) battery.charge_level.percentage = 51 (0x33) (int) battery.charge_level.rate = 506 (0x1fa) (int) battery.is_rechargeable = true (bool) battery.model = '01ED' (string) battery.present = true (bool) battery.rechargeable.is_charging = false (bool) battery.rechargeable.is_discharging = true (bool) battery.remaining_time = 178363 (0x2b8bb) (int) battery.reporting.current = 25070 (0x61ee) (int) battery.reporting.design = 48840 (0xbec8) (int) battery.reporting.last_full = 29190 (0x7206) (int) battery.reporting.rate = 506 (0x1fa) (int) battery.reporting.technology = 'Li-ion' (string) battery.reporting.unit = 'mWh' (string) battery.technology = 'lithium-ion' (string) battery.type = 'primary' (string) battery.vendor = 'SIMPLO' (string) battery.voltage.current = 11947 (0x2eab) (int) battery.voltage.design = 11100 (0x2b5c) (int) battery.voltage.unit = 'mV' (string) info.capabilities = {'battery'} (string list) info.category = 'battery' (string) info.udi = '/org/freedesktop/Hal/devices/computer_power_supply_battery_BAT0' (string) ----- and 'cat /proc/acpi/battery/BAT0/state' gives this: ----- present: yes capacity state: ok charging state: discharging present rate: 15961 mW remaining capacity: 24990 mWh present voltage: 11892 mV ----- It looks like 51% is the correct figure. -- Different discharge time in battery details and tooltip https://bugs.launchpad.net/bugs/182738 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
