Can you please provide more information about this problem? Specifically, please take a look at the information reported here and find out of this is the same problem that you are experiencing. -- http://bugzilla.ubuntu.com/show_bug.cgi?id=14050#c2 Thanks.
Yes, thats the behaviour. So mark it as duplication, thanks for your care
Actually, I'll reopen this and confirm it. This bug is caused by laptops with buggy ACPI implementations. This report that they are "discharging" when they really are not. The battery applet is now using a new HAL (hardware abstraction layer) battery status backend. The new backend doesn't have a work-around for these buggy laptops whereas the old backend does. There will be more people reporting this bug, I imagine, and this will give us a good place to track it until either the kernel is fixed to properly support these laptops or a work-around is added to HAL. In the meantime, if this bug affects you, please see the "Troubleshooting" section of the battery status applet help. It contains instructions for determining if you're using HAL and disabling it if you are. David: just out of curiosity -- what model of laptop do you have? Thanks for the report.

Please describe the problem: When my battery almost fully charged, applet shows, that it is working on Battery, but AC adapter is present. here is the Hal keys ac_adapter.present = true battery.present = true battery.rechargeable.is_charging = false battery.rechargeable.is_discharging = true ----------------- And from /proc/acpi/ ac_adapter/ADP1/state: on-line battery/CMB0/state: present: yes capacity state: ok charging state: discharging P.S. After recharging applet shows empty battery, but in tooltip -- 100% charged P.P.S in short: when battery lid on laptop is off -- the icon shows "working on battery, discharging" when on -- "Working on AC Adapter, Charging" Steps to reproduce: 1. Merge gconf files in your $HOME/.gconf (I've simply deleted this directory and then restarted gdm) 2. Add applet on your pannel Actual results: Expected results: Does this happen every time? Yes Other information: Distribution: Debian testing/unstable hal: 0.5.5.1-3 dbus: 0.60-1 kernel: linux-2.6.14
