Always says "Laptop battery is fully charged" when running on battery power

[Procedural Texture]

Binary package hint: gnome-power-manager

Gnome-power-manager 2.28.0 always reports "Laptop battery is fully charged" when running on battery power. I expected to be able to see remaining battery charge as a %.
Reports battery charge % correctly (and charge progress) when on AC power again.

Acer Aspire One (model 110, I think). 6-cell battery rather than standard 3-cell.
I've confirmed this bug in Ubuntu 9.10 Alpha 6 and Beta. It always worked fine in Ubuntu 9.04

I see that some historically *similar* bugs may show relevant behaviour when rebooting under battery power, but I started filing this report before knowing that might be relevant and useful information to append to this report.

Looks like the "Battery Information" is correct (14% in my case) but the DeviceKit info says 100%.

When it came down to 4% is suddenly started to show it correctly (and the red battery indicator).

The issue is still present after the last update on 25/10/2009 in my HP Mini 110 running Karmic Netbook Remix

I can confirm this bug is also an issue for me. As a workaround I suggest running an alternative power manger, eg: xfce4-power-manager, which will report battery state correctly.

I'm running Ubuntu 9.10 (installed RC, upgraded on release day) on my Dell XPS M1530, and I have this issue as well. Occasionally I can trick it into working, but it's hit-or-miss.

Specifically, I have my laptop plugged in right now, and it says "Laptop battery is fully charged". And now I've unplugged the laptop, and it says "Laptop battery discharging (80.8%)" (decreases every time I unplug again).

Thanks guys!

This bug also affects me, on an Acer Aspire One 110, 3-cell battery. Ubuntu 9.10 Netbook Remix, freshly updated as of this morning. Battery status applet shows 100% all the time, whether it's on AC or battery power. Does not auto-hibernate at low-battery state, just dies.

Come on guys... Lucid is were almost 3 months

This bug also affects me, on HP Pavilion dv3550eg with Ubuntu 10.04!
When starting Ubuntu with battery, it says "Laptop battery is fully charged" and shows the icon for being plugged; and finally dies without a word of warning.
If i plugged power to it and take it away again, it shows the right status and icon.

Affects me on Acer Timeline X 5820T running the latest Natty release 11.04 with kernel 2.6.38.11-generic amd64.

battery indicator shows as if the power is plugged in even when on battery and that the battery is fully charged.

The computer doesnt seem to notice the transition between running on mains and on battery..

Looking at the power stats in device information - this seems to be the case it also doesn't seem to pick up any realtime info on the battery or the ac adapter.
