Description Michel Alexandre Salim 2009-04-01 10:01:49 EDT
Description of problem:
g-p-m would incorrectly claim that the laptop's battery is broken, and fails to display the notification icon after that. Other functionalities (e.g. brightness keys) still work, but suspend/resume is no longer possible, either through the Main Menu or through the g-p-m systray icon (since it is not displayed, it cannot be right-clicked)

Going to try booting the -16 kernel revision and see if the problem was already present there; AFAIR it worked just fine yesterday.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Unplug AC adapter
2. killall gnome-power-manager && gnome-power-manager (tried with --verbose --no-daemon too; no difference)
3. Repeat with AC adapter plugged
Actual results:
The following pop-up notice is given in both (2) and (3):
Battery may be broken

Your battery has a very low capacity 69%), which means that it may be old or broken.
After that, the notification icon is not shown.

Expected results:
Should work as usual, regardless of whether g-p-m detects a broken battery or not

Comment 1 Michel Alexandre Salim 2009-04-01 10:14:55 EDT
Tried DeviceKit-power 006-3, 007-2 and 008-0.1.20090401git; the same problem occurs with all of them.

So there are two separate problems:
1. The battery is incorrectly reported as broken (/proc/acpi/battery indicates a working battery, and the charging level is definitely > 69 %)
2. If a battery is broken, g-p-m does not have an icon for it so if the user missed the initial warning, they would not be aware of the problem

False alarm; the 008 git snapshot works, but only after restarting the computer.
