After wakeup from sleep, gnome-power-manager does not detect it is running on battery

[Aniruddh]

Binary package hint: gnome-power-manager

I am running gnome-power-manager 2.28.1 on ubuntu 9.10.

What I expected:
After wakeup from sleep gnome-power-manager should show the remaining battery power.

What happened:
When suspended on battery power and later when the laptop wakes up (still in battery power), gnome-power-manager applet shows the AC adapter icon in the notification tray and it shows no tool tip.

I have attached the output of gnome-power-manager --verbose output.

I just observed that whenever laptop wakes up from a suspend, gnome-power-manager applet simply shows the ac adapter icon irrespective what the current state is. Looks like it is not able to detect the presence of the battery on wakeup.

Sorry for the name change, I was in the wrong report.

But I can confirm this behavior. I had filed a report on my own. See here: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/471888

I marked it as duplicate.

Thanks for pointing me to your bug. Are you aware of any way we can request
for this bug to be fixed sooner? I am not able to use suspend because of
this.

Thanks,
Aniruddh

For my HP DV-4 this bug looks like: http://bugzilla.kernel.org/show_bug.cgi?id=13449#c12

[Adam Lofts (adam-lofts)]

Compiling a kernel with the patch suggested in the above bug fixes the issue for me.

[Aniruddh (aniruddhasrao)]

Can we get this kernel patch as a kernel update for ubuntu? That would be very much useful for everybody.

[nameiner (nameiner)]

Adam,
Can you please help me to apply this patch. I downloaded the kernel sources and unpacked them. Now I'm stuck cause all the tutorials I found assume that I have a archive as source for the patch. But I don't know how to get this.
Thanks, your help is appreciated.

[Adam Lofts (adam-lofts)]

Just to reiterate: This is only going to help you if you have an HP DV-4 laptop. To build a patched kernel do:

[Install some packages (look at a tutorial)]

tar -xjf /usr/src/linux-source-2.6.31.tar.bz2
cd linux-source-2.6.31/
cp -vi /boot/config-`uname -r` .config
patch -p1 < /home/adam/Desktop/0001-ACPI-add-DMI-entry-for-SCI_EN-resume-quirk-on-HP-dv.patch
make menuconfig
fakeroot make-kpkg --initrd --append-to-version=-adam-hpdv4 kernel-image kernel-headers
sudo dpkg --install ../*.deb

[nameiner (nameiner)]

Thanks Adam.

After patching the kernel and installing it I can confirm that this patch works.
Now it only needs to make its way into the ubuntu kernel.

[Jeremy Foshee (jeremyfoshee)]

marked the g-p-m task as invalid. Added a kernel task. I have put this on my list.

[Jeremy Foshee (jeremyfoshee)]

Aniruddh,
      Please test against the latest daily build of lucid. You can use the daily live ISO. Let me know if this is resolved as the patch should have made it into the kernel via stable branch updates.

Thanks!

-JFo

[nameiner (nameiner)]

I tested it with the alpha3 live CD and it seams to be fixed.

[Aniruddh (aniruddhasrao)]

It worked for me too. Is it possible to get this fix into 9.10 kernel?

[Jeremy Foshee (jeremyfoshee)]

nameiner,
     Thanks for your testing. :)

Aniruddh,
     This doesn't necessarily meet the requirement for an SRU, but I will inquire with the Kernel Engineers to see what their thoughts are on the subject.

Thanks!

~JFo

The patch cited is already committed in that release as the commit is in v2.6.32 the baseline for lucid:

Closing off the Lucid task for this bug.

Just to notify that the same problem is happening with an acer travelmate 7730G.
I hope the fix will not be realized only for HP notebook.

The diff patch seems to check specifically for HP notebook.
+ .ident = "Hewlett-Packard Pavilion dv4",

How is the final fix: general purpose or HP specific ?
