maverick: gnome-power-manager does not display battery percentage on left icon click, even when told so by gconf-editor - instead wants to calculate time even if not possible

Bug Description

Binary package hint: gnome-power-manager

Since upgrading from lucid to 10.10 maverick, gnome-power-manager (icon) does not display remaining battery percentage on my laptops as I was used to and which is the only possibility as the hardware is already a bit of age and does not support this time estimation (HP Omnibook XE3-GC, built around 2001). Instead, it wants to display the estimated remaining time which cannot be calculated, therefore on a left click it says in German "wird ermittelt...", which could be something like "being estimated" or "being calculated" in English.

gconf-editor provides a setting for disabling the time-based display of information, but it does not seem to work - percentage does not become available on tool tip / left click.

All information about the battery is present when opening the detailed dialog, so it seems to be just a problem about selecting the value for display.

Please make the percentage available again, at least according to the gconf-editor option or based on a mechanism that disables time estimation as soon as it detects to be impossible.

I have the same problem using a HP Pavilion tx2000 laptop. I can confirm that the applet works correctly under Lucid, but will only display "Laptop battery (estimating ...) under Maverick.

Not much to add, except I'm experiencing the same situation with Maverick on MSI Wind U100 running desktop edition

I found a a solution to this on another bug thread:

It still only shows percentage power remaining and not time remaining, but this is good enough for me. Hope this is helpful to someone.

Hello Toni,

thanks for your comment - this works perfectly for me, the display shows a usdeful percentage value again!

Changed in gnome-power-manager (Ubuntu):
status: New → Confirmed

After several charges and discharges and also switching my system to the mainline kernel 2.6.36 (while still using the PPA version of the _tools_, never used that older kernel there), I even experience a great dynamic behaviour - it seems to be able to calculate a useful remaining time under certain circumstances and displays it in this case. If it cannot be calculated, the percentage is displayed instead. That's exactly what I expect as the best solution - but still it is not in the base maverick system.

i have the same problem on a hp pavillion dv7 2070 eg.
The battery status can be displayed with (for instance) docky.

it worked in lucid....

I have this same problem on my HP G62 laptop.
