I've had this issue for as long as I can remember, and it's still present in 14.04. I have apparently the same battery as the bug reporter. I'm running on an Acer Aspire 5050-5554.
I don't know if it's due to changes in acpi since 2009 or because of a different symptom, but my output is slightly different, especially state -> remaining capacity. $ cat /proc/acpi/battery/BAT1/alarm alarm: unsupported $ cat /proc/acpi/battery/BAT1/info present: yes design capacity: 4000 mAh last full capacity: 64675 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 300 mAh design capacity low: 2587 mAh cycle count: 0 capacity granularity 1: 32 mAh capacity granularity 2: 32 mAh model number: ZR3 serial number: 40696 battery type: LION OEM info: SONY $ cat /proc/acpi/battery/BAT1/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 0 mAh present voltage: 12193 mV Fun fact: if I boot into Ubuntu with the AC adapter unplugged, I can run off the battery for at least 10 minutes. But if I unplug AC while Ubuntu is running, it goes into critical shutdown mode. I've always assumed that the battery hardware controller was faulty. However, the battery light will also turn yellow after the adapter's been unplugged, which suggests to me that the hardware itself may have a more accurate internal reading of the charge state. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/358807 Title: battery monitor show only "0%" off battery charge in ACER Aspire 5050-3284 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/358807/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
