One of the team members posted the DSDT info for a ASUS U41SV laptop. The two calls to turn on/off the card are like this:
\_SB.PCI0.PEG0.GFX0.DOFF
\_SB.PCI0.PEG0.GFX0.DON
Code snippet:
If (LEqual (_T_0, 0x03))
{
And (Local0, 0x03, Local0)
If (LEqual (Local0, 0x01))
{
\_SB.PCI0.PEG0.GFX0.DON ()
Return (0x01)
}
Else
{
If (LEqual (Local0, 0x02))
{
\_SB.PCI0.PEG0.GFX0.DOFF ()
Return (0x00)
}
Else
{
Return (\_SB.PCI0.PEG0.GFX0.DSTA ())
}
}
Return (0x01)
}
