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 have opened a bug in kernel bugzilla and attached every info I could think of. http://bugzilla.kernel.org/show_bug.cgi?id=10855 I have this laptop since about 2.6.22 and it was like that since then, so it's not a regression. All the similar issues I see in Internet mention MSI laptops. I will increase the debug level now and see if something interesting pops up. If it does, I'll report back.
