Hello!
I have a notebook.
System doesn't change energy consumption policy when I unplug ACAD.
# service acpid stop
# cat /proc/acpi/event
processor CPU0 00000080 00000001 <----- unplug ACAD
processor CPU0 00000080 00000000
No any messages about ACAD.
My dsdt.dsl have two following interesting sections:
1.
Device (AC)
{
Name (_HID, "ACPI0003")
Name (_PCL, Package (0x01)
{
\_SB
})
Method (_PSR, 0, NotSerialized)
{
If (\_SB.PCI0.EC.ADP)
{
Store (0x03, \DBUG)
Store (Zero, \_PR.CPU0._PPC)
}
Else
{
Store (0x01, \DBUG)
Store (0x01, \_PR.CPU0._PPC)
}
Notify (\_PR.CPU0, 0x80)
If (\_SB.PCI0.EC.ECOK)
{
Return (\_SB.PCI0.EC.ADP)
}
}
2.
Method (_Q16, 0, NotSerialized)
{
Notify (\_SB.AC, 0x80)
If (\_SB.PCI0.EC.ADP)
{
Store (0x03, \DBUG)

}
Else
{
Store (0x01, \DBUG)
Store (0x01, \_PR.CPU0._PPC)
}
Notify (\_PR.CPU0, 0x80)
}
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!
