Summary: battery status info dissapears on MSI PR200
Product: ACPI
Version: 2.5
KernelVersion: 2.6.26-rc4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
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.
