Bug Description

Binary package hint: gnome-power-manager

On Karmic (I didn't encounter this in older versions) 32 or 64 bit, gnome-power-manager icon always indicates that the battery is fully charged. Right now, I have the fully charged and plugged battery icon and the mouse hover tooltip says that the battery is fully charged. However, clicking the icon says that my battery is 11.5%. Conky and Kubuntu's battery monitor says the same.

Hello all,

This is the same that happens to me. In particular:

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 frequently the remaining power, the computer
just runs out of battery and halts abruptly. When restarting, I had
to fscheck the filesystems. This is very dangerous.

However, I found a "trick" while this issue is not successfully addressed.
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 than before.

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):

I have a Fujitsu Esprimo U9200 Running Ubuntu 10.04, and I have the same problem.

Plug the AC charger in and I get the "discharging" pop up

Unplug the AC charger and the battery icon goes fully green

Strange behaviour. The battery does charge and discharge as it is meant to, but it is just Ubuntu is reading things some what in reverse.

Still having the same issue on 10.04 32bit. If I'm not mistaken, this is
also true for 64bit.

Yes, I'm still having this issue on Lucid 64-bit. After booting on battery power the Gnome indicator claims my battery is charged and connected to AC power. I can access the correct charge level by opening the power statistics window, or by plugging and unplugging the AC adapter.

My hardware configuration (sudo lshw) is attached.

Problem still exists in Ubuntu with the power meter showing the incorrect state however;

- Ubuntu Host XP guest, XP will show correct battery charge and discharge states

- Also installing WMbattery in Ubuntu (from repo's) shows the correct state in it's graphic monitor, if only that one could be used in the system panel

seems like an easy fix, but there are quite a few bug reports on this, over the years and so far no one has been able to correct it.
