Example, HPDV9000:
If (LEqual (Local1, 0x07))
{
Store ("Fn+F7 Pressed", Debug)
If (LEqual (OSYS, 0x07D6))
{
If (IGDS)
{
Notify (\_SB.PCI0.GFX0.DD04, 0x87)
}
Else
{
Notify (\_SB.PCI0.PEGP.VGA.LCD, 0x87)
}
}
Else
{
Store (0x15, SMIF)
Store (0x00, TRP0)
}
Fn+F7 = screen darker. See the ref to OSYS.
Also:
Method (_Q16, 0, NotSerialized)
{
Store ("!!! DVD/Music Button pressed !!!", Debug)
If (LEqual (OSYS, 0x07D6))
{
And:
If (\_OSI ("Windows 2006"))
{
Store (0x07D6, OSYS)
}
