Hi ronovar,

here is my DSDT: http://www.mediafire.com/?minsslmjzcg66r2

i tried adding your fix to my dsdt, it compiles fine no errors, but shutdown still doesnt work.

also in the beginning of the DSTD yours has:

External (\_SB_.PCI0.HBDP)

and mine has:

External (\_SB_.PCI0.LPCB.S5CT) which is responsible for shutdown as you said.

I am using Chameleons Graphic Enabler.
also here is something interesting: http://www.insanelymac.com/forum/ind...owtopic=152566
at the end of the thread there is an archive to download with ioregs and smbios dumps from real mac`s and there are one of MacBookPro5,3 and one of MacBookPro5,1 as we use it, maybe there is some fix we can load in our DSDT`s.

Cheers
