Hi all,

So I checked out the latest acpi_call from git, ran make and inserted
the module.  When I run the test_off.sh script I find a method that
works.  However, my battery time remaining goes *down* not up.  I also
have a modified version of the script that basically only tries the
method that worked for my laptop (\_SB.PCI0.PEG1.GFX0._OFF) and I
replace OFF with ON.  Afaict this will turn the discrete graphics back
on.  When I do this my battery life now shows an additional two hours
remaining.

This makes no sense to me, so I'm wondering if I'm misunderstanding
the purpose of the script.  I thought this script was designed to turn
off the discrete graphics chip so I had less battery drain.  However,
from this testing it seems I get more battery drain when it is off.
Am I wrong?

- Pete
