I pulled the DSDT for the Asus U30JC, for suspend/resume, there are
two methods, _PS3 and _PS0:
echo '_SB.PCI0.PEG1.GFX0._PS0' > /proc/acpi/call
or
echo '_SB.PCI0.PEG1.GFX0._PS3' > /proc/acpi/call
Method (_PS0, 0, NotSerialized)
{
\DIAG (0x70)
Store (Zero, \_SB.PCI0.GFX0._PSC)
If (LNotEqual (\_SB.PCI0.GFX0.DGPS, 0x00))
{
\_SB.PCI0.PEG1.GFX0.DON ()
Store (Zero, \_SB.PCI0.GFX0.DGPS)
}
\DIAG (0x71)
}
Method (_PS3, 0, NotSerialized)
{
\DIAG (0x72)
If (LEqual (\_SB.PCI0.GFX0.P3MO, 0x01))
{
Store (0xC0, HPD)
\_SB.PCI0.PEG1.GFX0.DOFF ()
Store (0x03, \_SB.PCI0.GFX0._PSC)
Store (0x01, \_SB.PCI0.GFX0.DGPS)
}
Store (0x00, \_SB.PCI0.GFX0.P3MO)
\DIAG (0x73)
}
