1. ACPI names are 4 bytes long, so AC will be padded with _.
2. Your output shows that there is no handler for AC event, do you have ACPI AC driver compiled and loaded?

Hello!
I have a notebook.
System doesn't change energy consumption policy when I unplug ACAD.
# service acpid stop
# cat /proc/acpi/event

No any messages about ACAD.
My dsdt.dsl have two following interesting sections:
1.

}
2.

Method _Q16 always called when I unplug ACAD.
For instruction: Notify (\_SB.AC, 0x80)

Why there is string "No notify handler for Notify(AC__, 80) .... ???
Another notify (Notify (\_PR.CPU0, 0x80)) works fine!
Why there is "AC__" not "AC" ?
Thanks!
