Thanks for the acpidump
Looks a lot like that on the Quanta boards from HP...
We need to disable OSI(Linux) on this box if we want
the proposd PNP0C32 to work.
-Len
Scope (\_SB)
{
Name (LINX, 0x00)
Name (OSTB, Ones)
OperationRegion (OSTY, SystemMemory, 0x2FE9FF4C, 0x00000001)
Field (OSTY, AnyAcc, NoLock, Preserve)
{
TPOS, 8
}
Method (OSTP, 0, NotSerialized)
{
If (LEqual (^OSTB, Ones))
{
If (CondRefOf (\_OSI, Local0))
{
Store (0x00, ^OSTB)
Store (0x00, ^TPOS)
If (\_OSI ("Windows 2001"))
{
Store (0x08, ^OSTB)
Store (0x08, ^TPOS)
}
...
If (\_OSI ("Windows 2006"))
{
Store (0x40, ^OSTB)
Store (0x40, ^TPOS)
}
If (\_OSI ("Linux"))
{
Store (0x01, LINX) // NOP -- never refereced after set
Store (0x80, ^OSTB)
Store (0x80, ^TPOS)
}
PHNP0C32 looks for OSTB == 0x40, which this code clobbers,
so OSI(Linux) will disable that:
Device (MBTN)
{
Name (_HID, EisaId ("PNP0C32"))
Name (_UID, 0x01)
Method (_STA, 0, NotSerialized)
{
If (LEqual (\_SB.OSTB, 0x40))
{
Return (0x0F)
}
Else
{
Return (0x00)
}
}
Method (GHID, 0, NotSerialized)
{
If (DMED)
{
Notify (MBTN, 0x02)
}
Return (Buffer (0x01)
{
0x01
})
}
}
