Description of problem: ACPI is unable to show AC adapter status on HP Omnibook 500 Version-Release number of selected component (if applicable): 2.4.20-2.2 How reproducible: always Steps to Reproduce: 1.modprobe ospm_ac_adapter Actual results: cat /proc/acpi/ac_adapter/0/status always show "Status: on-line", even if laptop is running on battery power. Expected results: /proc/acpi/ac_adapter/0/status must be changed if power cord is pulled off. Additional info: APM show battery/power adapter status OK
Similar on sony vaio: Status: off-line is shown, no matter of the actual status. This works fine with a stock 2.4.20 + current acpi patch.
Works for me on Dell Lattitude C640 (so far it seems to be the *only* ACPI feature that does work for me...) - /proc/acpi/ac_adapter/0/status correctly shows the AC status.
