Blank screen on Aspire one when less than 22% (9 cells) battery

[Yann Le Doaré]

After changing my 3 cell battery with 9 cell one, i have this bug :

- when battery is less than 22% charged, there is a blank screen
- restarting into BIOS setup is OK (I can stay a long time)
- restarting with "acpi=off noacpi" option is OK (I can use my comptuter more than an hour)
- restarting without options makes blank screen after one or two minutes.

I think it is an ACPI bug, but how can I do to resolve it ?

Note : I Tried other kernels (3.0, 2.6) and other distros witout success.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. 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.

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

In the past, I debuged linux kernel with serial console, nowdays (my aspire one has not serial port) what is the way to try to debug kernel errors ?

[sm8ps (sm8ps)]

In the hope that the following remarks be helpful: I use an Acer Aspire One 150 with Ubuntu 12.04. I sometimes use a 9-cell battery (11Ah) which used to give me about 10 hours of independence under Ubuntu 10.04. The 3-cell gives me about two hours now on Ubuntu 12.04.

The other day, I hibernated the machine and exchanged the 3-cell with a 9-cell battery (11Ah), intending to get a full day of battery life thereafter. The 3-cell battery had been at a little less than 50%, the 9-cell had been fully charged overnight to 10Ah (90% capacity). For some reason, the battery indicator turned red after less than two hours and soon afterwards the system had to be shut down and could not be revived on that battery.

Today, I needed to do the same but abstained from hiberating the machine and turned it off instead before switching batteries. Nevertheless the battery indicator went down and indicated only 1:30 remaining after less than two hours of usage which cannot be the case.

I was prepared to switch to paper and pencil or bow and arrow or whatever I would find when oll of a sudden the battery indicator jumped back up to 57% with a remaining time of more than 4:30. I captured the screen of the battery statistics showing the time until discharged over the last three hours. This is all with one and the same 9-cell battery.

Soo, what is the deal here? For some reason, the change of battery did not get registered even during the first two hours of usage but only afterwards. I could not tell what triggered it. (Indeed I would know how to trigger a refreshing of that information. -- I did close the lid which only shuts off the screen, come to think of it. I am going to try that next time and see what it does!)

I installed Windows XP on this comptuter -> same problem !

You can close this bug, which must be an hardware one.

Thanks
