Bug Description


I have Toshiba Satellite L640 and Ubuntu 11.10 installed on it.

But Ubuntu is not recognizing the batteries. I have 6 batteries installed. Even Ubuntu 11.04 did not recognize the batteries.

Please help me resolve this problem.

Because of this problem, I am not able to work on the laptop using battery. It does not hibernate on low batteries. Instead abruptly switches off.

I have a Toshiba Satellite L655 with Ubuntu 11.10. I have had this problem since I had this lapop.

I have been able to fix it manually by compiling the kernel from source, editing the DSDT file. (See http://techinterplay.com/fix-toshiba-battery-issue-linux.html. Unfortunately, I cannot get to this website because of my school's proxy.)

This problem is very annoying because you have to do this every time a new kernel comes out.


Please run this command on the affected machine:
apport-collect 871594
After doing so, please verify that information was automatically attached to this bug report and that the "apport-collected" tag was automatically added (please do *not* manually add it yourself). If this is the case, then you can go ahead and change this bug's status back from Incomplete to Confirmed. The automatically attached information should hopefully make this report complete enough to be worked on by a developer.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help, we really do appreciate it.

Can you please give me a quick way to update the Kernel in my laptop?

I actually installed 10.04 and then upgraded to 11.04 and again upgraded to 11.10.

Rajkumar B

Use the Update Manager to update everything. Then reboot, to put the new kernel into use. After rebooting, you can run "uname -r" to check the kernel version in use, and compare it to the latest version listed at https://launchpad.net/ubuntu/+source/linux (scroll down to The Oneiric Ocelot).

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the release candidate kernel versus the daily build. 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.

Still doesn't work. the top few lines of 'acpitool -e' says:

Kernel version : 3.1.0-999-generic - ACPI version : 20110623
Battery #1 : slot empty
AC adapter : on-line

This is using the daily kernel made at 12:43 today.
Is there any other information I need to add?

Joseph Salisbury (jsalisbury) wrote :

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

I cannot get to bugzilla.kernel.org. I think it is still down from the time it was hacked.

I am also unable to load http://bugzilla.kernel.org/. Hopefully it will be back up soon.

Rajkumar (brajkumar) wrote :

When will the bug status change to In-Progress from Triage?

This will happen once one or more developers indicate that they are actively working on the bug. Since this has been found to be an upstream problem, it will almost certainly not happen until the bug is reported upstream (or until a report is found upstream for it), which cannot happen until bugzilla.kernel.org is back up.

A new kernel just came out yesterday. (3.0.0-13) I have installed it
I noticed that support for my wired network is included (this was not really a problem for me).
It still cannot detect my battery.
Bugzilla is still down.

Rajkumar, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

I tested the daily image on my laptop last week and it detected the battery.
Rajkumar, can you confirm this? You have a different model than me.
