Description Leonid Podolny 2008-06-04 12:16:12 UTC

Latest working kernel version: None
Earliest failing kernel version: 
Distribution: Gentoo
Hardware Environment: MSI PR200
Software Environment: Gentoo 
Problem Description: 
My laptop stops recognizing both its battery and ac_adapter. With both the battery fully charged and AC plugged in:

looptop ~ # cat /proc/acpi/battery/BAT1/*
present:                 no
present:                 no
present:                 no
looptop ~ # cat /proc/acpi/ac_adapter/ADP1/*
state:                   off-line

I also stop seeing ACPI events in dmesg.
After a reboot, these files have sane values for a while, but then, in a matter of minutes, something happens and it reverts to the wrong situation as described above. dmesg displays some errors during boot-up, but I don't think it's relevant because the system runs fine for some time after. I'm attaching everything to the bug.
I have this laptop since about 2.6.22 and it was like that since the beginning. All the similar issues I see in Internet mention MSI laptops.

Please check if the bug 10699 is the same, e.g. if patches there help.

Alexey,
I can't load the msi-laptop module, because it doesn't support the pr-200 model.

looptop ~ # modprobe msi-laptop
FATAL: Error inserting msi_laptop (/lib/modules/2.6.26-rc4/kernel/drivers/misc/msi-laptop.ko): No such device

As far as I understand, the bug 10699 is about msi-laptop module messing things up. Here, it's obviously not the case, as I can't load this module even if I want to.

Comment 7 Leonid Podolny 2008-06-05 09:33:02 UTC

Sorry, if I've been rude. 
Applied the patch, recompiled. No luck :(

Comment 8 Leonid Podolny 2008-06-15 11:10:39 UTC

This issue was solved after I upgraded to 2.6.26-rc6. What do I do, close the bug?

Comment 9 Alexey Starikovskiy 2008-06-15 14:34:46 UTC

thanks

I have also a MSI PR200 laptop, but is probably different in some regards.

The model is: MSI PR200WX-058EU and I can't load the msi-laptop module, either.

heidi:/home/eddy/usr/src/osm/planet/git-planet-rom# modprobe msi-laptop 
FATAL: Error inserting msi_laptop (/lib/modules/2.6.26-1-amd64/kernel/drivers/misc/msi-laptop.ko): No such device


I am running the Debian Lenny 2.6.26-1-amd64 kernel. I have also issues related to suspend to ram, but I will take issues one at a time.


Please tell me what information you need me to supply.

acpidump for MSI PR200WX-058EU

This dump seems to be different from the one provided before by Leonid.

Eddy,
First, msi-laptop has nothing to do with PR200, it's for some other older
versions. 
Second, this issue is currently being worke on in this bug: 
http://bugzilla.kernel.org/show_bug.cgi?id=12011. There are some patches in
that bug, I still hadn't time to check if any of those help. Anyway, I don't
think the patches there will work (or apply) with kernel as old as 2.6.26.

OK, I saw that comment in comment #6 and I was under the impression that I needed msi-laptop on PR200.

I don't mind trying a patched linus git tree.

I compiled 2.6.29-rc7 and it correctly detects when on battery and when not.

Now I'll have to report just the sleep issue.
