System freezes when battery powered

[Thomas Lenarz]

Laptop ASUS X51R freezes when battery powered with Ubuntu 10.04

No problems when AC powered.

Two scenarios to reproduce the problem:

a)

1. Boot up Ubuntu with AC supply disconnected but battery powered.
2. Ubuntu will freeze somewhere during boot process before login screen is displayed. I think it happens around the time X is started. In most cases get fancy patterns displayed on screen, more rarely screen stays blank.

b)

1. Boot up Ubuntu with AC supply connected.
2. Logon to the system.
3. Gnome Desktop is displayed.
4. Pull the plug of AC.
5. It takes about 1 or 2 seconds. Screen freezes.

Laptop is more or less useless for me without the possibility of using it battery powered.

I am a quite experienced C/C++/Java application programmer, but know few to nothing about system programming. However you could come back to me and guide me in which logs to look or what to do to trace down the problem.

Thanks
Thomas

I just came across to see that there is a ubuntu-package for the proprietary-graphics-driver fglrx available. I gave it a try. The problem seems to occur less with this driver than with the open source radeon-driver. I got the system booted up with battery-power. And it generally worked fine disconnecting and reconnecting the AC-supply.

However, once the system froze as well on disconnecting the AC-adaptor.

All the Best,
Thomas

Problem stays the same with Ubuntu 10.10 Release. Tested with life CD.

[santiago (santiagozky)]

Apparently the problem still exists in maverick. There are several people talking about it in the forums:

http://ubuntuforums.org/showthread.php?t=1595196

I am also experiencing freezes on 10.10 when running on battery. With 10.04 I never had that problem. The problem started the same day I upgraded so I don't think is a hardware issue.

I cannot see any error on the logs. The computer just freezes and won't even respond to a REISUB. The freezes are very random, from just a few seconds after logging in to several hours

I do get many of these (1 each 5 seconds)
Oct 19 02:19:10 ubuntu kernel: [ 9147.643059] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded

[Nikunj (nikunjm)]

Very similar to the problem posted, but my system was just fine when using 10.04. it was only when I updated to 10.10 that the freezes started.

There is a forum thread with a number of people who have the same problem describing their hardware. the URL is http://ubuntuforums.org/showthread.php?p=10029746#post10029746
.

The logs dont show anything useful. From my observation the freeze strikes wheneven on battery and any power related activity occurs, like insertion of USB drive, switching on wi-fi etc.

[Michal (michal-ciza)]

I have the same problem. System freezes completely once I plug out the power supply. And also if I start system without power supply it freezes once the Wi-Fi network is started. I can do nothing except hard shutdown.

My laptop:

DELL XPS 1340
Nvidia G210M
Ubuntu 10.10

Please help.

This should be marked as critical! A laptop turns out useless without the ability to use it on battery power.

Thomas Lenarz, 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 capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ? As well, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
