Either battery status icon not being shown, or the icon showing "Laptop battery is charged".

[cshong]

Binary package hint: gnome-power-manager

I am using Ubuntu 10.04.

I am not sure whether this bug really related to gnome-power-manager or not. So, if wrong, please give me chance to correct it.

Under general tab in power management preferences (System -> Preferences -> Power Management -> general), I had set the notification area to "Only display an icon when charging or discharging". If I use battery to power my computer without power adapter, no icon had been displayed on the taskbar, same thing happen if I plug in my power adapter to charge the battery.

If I set the notification area in System -> Preferences -> Power Management -> general to "Always display an icon", a battery icon has been displayed on the taskbar. But, doesn't matter I am charging or discharging the battery, when I click on the battery icon, it will display "Laptop battery is charged".

Hi all,

I am also using Ubuntu 10.04 amd64 on a HP dv3000 and the same problem occurs!
First the icon on the general tab disappeared, I re-stablish using the following commands:

gconftool-2 --shutdown
rm -rf ~/.gconf/apps/panel
pkill gnome-panel

Now the problem is, when charging mode, the icon displays correctly the grey bar updated with the remaining percentage to complete de charge but when using only the battery to power my computer the icon is always charged to 100%. If I click on the icon and choose the first option I can see 37% but nevertheless the icon is always full load (100%).

 Regards,
Pedro

I have the same problem with Acer Aspire 5745G.
The icon of battery shows the battery always charged (100%).
I think that there is this problem because the notebook is too new!

Previous states are taken while the laptop is disconnected from power supply.

Hi cshong,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Acer Aspire 5745G.
kernel 2.6.35-6 - PAE

Error present

[Francesco Pretto (ceztko)]

Good job DisDis! I removed the "needs-upstream-testing" tag as told in the automated message.

Same here, Acer Aspire 4745G

Hmm. This problem has recently appeared for me on my Toshiba Satellite A200 running amd64 Maverick with the 2.6.35-14 kernel. I don't get an icon at all, and no battery tab in gnome power manager. Been running Ubuntu since 8.10 on this laptop and this problem has only cropped up recently.

I also don't get notifications when I adjust screen brightness anymore, I think that's related.

I had this bug in Ubuntu 10.04 with Acer Aspire 5745G. Acer released an update of BIOS (to v. 1.15) and this bug not appeared anymore.

Declining the Lucid and Maverick specific nominations for now and leaving this open against the actively developed Ubuntu kernel (which happens to be Maverick at this time). Will re-open the nominations should a fix be narrowed down which we can confirm specifically resolves this issue in Lucid and Maverick and qualifies for a Stable Release Update.

[cshong (cshong87)]

I tried the mainline kernel for Lucid, version 2.6.35-rc1, my Ubuntu does not even boot with this version.

I also upgraded to the latest bios, still not work.

[cshong (cshong87)]

Also not work in Ubuntu 10.10.

[Evandro P. Alves (evandro-pa)]

I just bought an Acer Aspire 5820TG and had the same problem before upgrading BIOS from 1.13 to 1.19. Now everything is working fine on stock Maverick

[Criz griffin (griffn9)]

I installed ubuntu 10.0 on Acer 4745G, upgrade to kernel 2.6.35-25 and 2.6.36 then upgrade bios. But this still not fix the problem,
Any suggestion, please?
thanks in advance

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
