Public bug reported:
Binary package hint: gnome-power-manager
When I switch on my computer using only the battery, the Battery monitor
on the tray is showing ALWAYS that the battery is fully charged.
However, making a simple click onto the monitor icon, it shows a popup
with the actual percentage of remaining battery. In this situation, if I
do not verify every while and while the remaining power, the computer
just runs out of battery and switch off abruptly. When restarting, I had
to fscheck the filesystems.
However, I found a trick. All this changes when I simply connect the PC
to the power (just less than a second) and the monitor changes:
* A popup shows that the the battery is discharging, as well as the remaining
battery percentage and the time.
* The tray icon is showing that the battery is discharging.
* The popup information when click the icon remains the same.
In this situation, the battery monitor shows 2 alerts: the first one
some time before running out of battery (about 9% of battery) and the
second one when only 1-2% of battery remains. In both cases, the popup
alert shows correctly the percentage of battery, but do not show the
proper remaining time (just "unknown remaining time" or so). In
contrast, in this case, the computer switch off normally (as I have set
up in the settings).
All these problems appeared when upgrading to Karmic. In the previous
ubuntu release, all worked really fine.
My hardware settings are as follows (sudo lshw):
