I have problems with my Dell E6410 running 11.04 Natty Narwhal. I noticed some strange values for BAT0 (I have BAT1 but not installed). The following were from when my computer's battery was fully charged and on AC power:
$ cat /sys/class/power_supply/BAT0/charge_full 8061000 $ cat /sys/class/power_supply/BAT0/charge_now 8400000 $ cat /sys/class/power_supply/BAT0/charge_full_design 8400000 Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 vendor: SMP model: DELL HJ59002 serial: 6061 power supply: yes updated: Tue Nov 29 14:48:33 2011 (631 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: fully-charged energy: 93.24 Wh energy-empty: 0 Wh energy-full: 93.24 Wh energy-full-design: 93.24 Wh energy-rate: 2.997 W voltage: 13.038 V percentage: 100% capacity: 95.9643% technology: lithium-ion $ upower -v UPower client version 0.9.9 UPower daemon version 0.9.9 So may battery says it has 100% charge, but that it is no longer capable of 100% charge (capacity = 95.9643%). The battery charge indicator in Gnome (classic) displays what looks like a critical battery icon (red battery outline), but the drop-down menu lists "Laptop battery is charged." Sometimes I will get an indicator that the battery is critical as soon as I unplug AC power, at which time it will hibernate. It seems like there is some error when it receives values with charge_now > charge_full. Does anyone else with this problem see similar values? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/531190 Title: upower (devkit-power) reporting bad data when AC cable is unplugged To manage notifications about this bug go to: https://bugs.launchpad.net/devicekit-power/+bug/531190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
