Hi. This looks like an ACPI issue. I'm no expert in ACPI and the Linux
kernel, but have you tried updating the machine's BIOS to the latest
version?
Also, may I suggest reporting the result of running the command "udevadm
monitor --property" for several minutes after you unplug the power
adapter? Does it contain "change" events like the following?
KERNEL[88992.976211] change
/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 (power_supply)
ACTION=change
DEVPATH=/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0
POWER_SUPPLY_CHARGE_FULL=881000
POWER_SUPPLY_CHARGE_FULL_DESIGN=4400000
POWER_SUPPLY_CHARGE_NOW=852000
[...]
UDEV [88992.982757] change
/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 (power_supply)
ACTION=change
DEVPATH=/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0
POWER_SUPPLY_CHARGE_FULL=881000
POWER_SUPPLY_CHARGE_FULL_DESIGN=4400000
POWER_SUPPLY_CHARGE_NOW=852000
POWER_SUPPLY_CURRENT_NOW=0
The result of the command "acpitool --battery" would also be useful as well.
You may also try posting your problem on the linux-pm mailinglist [1],
where the linux power management developers hang out.
