Thanks, that's really helpful module!

I have found out, that it's \_SB.PCI0.PEGR.GFX0._OFF for my
laptop most likely. I have no /proc/acpi/battery and acpi -bi
doesn't show the drain, so I can't tell with 100% certainty if
it worked, but dmesg says "[31760.893061] acpi_call: Call
successful", so i guess at least _something_ happened :)

Just wanted to let people know of this command, because i didn't
see it listed on blogspot.

Cheers!
