Help Dell Vostro 1400 doesn't shutdown

[leitor]

Hi,

 

I have just installed snow leopard 10.6.3 on a vostro 1400, 8400M gs 128mb, 4gb RAM, 1.8ghz c2d.

 

It would be all good except for the problem that it just doesn't shutdown, i have already tried openhaltrestart evoreboot kexts..

 

and the following dsdt shutdown fixes:

 

 

OperationRegion (PMRS, SystemIO, 0x1030, One)
Field (PMRS, ByteAcc, NoLock, Preserve)
{
, 4, 
SLPE, 1
}
Method (_PTS, 1, NotSerialized)
{
	If (LEqual (Arg0, 0x05))
	{
		Store (Zero, SLPE)
		Sleep (0x10)
	}
}

 

and

 

this

 

Method (_PTS, 1, NotSerialized)
{
	If (LEqual (Arg0, 0x05)) {}
	Else
	{
		...  original codes...
	}
}

 

None of them worked.

 

I only have HPET fix and CMOS reset fix on my dsdt...

 

here follows my current dsdt attached.DSDT.dsl.zip

 

Please help
