Clamshell Sleep via DSDT

Close! It sleeps when the Lid is open instead of closed. Right now I can put it to sleep manually but once awake and the lid is open it keeps going back to sleep...

Update:

I tried:

Device (LID0)
        {
            Name (_HID, EisaId ("PNP0C0D"))
            Name (LSTS, Zero)
            Method (_LID, 0, NotSerialized)
            {
                If (ECOK)
                {
                    If (LEqual (^^PCI0.LPC.EC0.ECLS, One))
                    {
                        Store (Zero, LSTS)
                    }
                    Else
                    {
                        Store (One, LSTS)
                    }

                    If (IGDS)
                    {
                        Store (LSTS, LIDS)
                        Store (LSTS, ^^PCI0.OVGA.CLID)
                    }

                    If (LIDS)
                    { 
                        Notify (SLPB, 0x80)
                    }
                    Return (LSTS)
                }
                Else
                {
                    If (IGDS)
                    {
                        Store (LIDS, ^^PCI0.OVGA.CLID)
                    }

                    Return (LIDS)
                }
            }
        }

Now it sleeps when the lid is closed, but I still get the loop where after wake it keeps going back to sleep... Do I need a Return?

Alright! One more kext scratched off the list! It needed to be inserted here:

If (ECOK)
                {
                    If (LEqual (^^PCI0.LPC.EC0.ECLS, One))
                    {
                        Store (Zero, LSTS)
                        Notify (SLPB, 0x80)
                    }
                    Else
                    {
                        Store (One, LSTS)
                    }

Thanks once again for the help mormegil... someone buy that man a beer! Now just have to fix issues with battery meter (VoodooBattery is only 32bit) and No sound after sleep issue with patched AppleHDA via DSDT (VoodooHDA v2.2 doesn't let me adjust volume).

Re: VoodooBattery is only 32bit. Superhai's published the source. Can't it be "ported" and compiled for 64-bit?

I HAVE THE SAME PROBLEM CAN U HAVE A CHECK OF MY DSDT AND GIVE ME SOME ADVICE?

HERE IS MY DSDT. I ALSO HAVE SOME GFX0 FAMILY MATCH ERRORS.

and here is mine as well, i already have sleep on lid close but cannot wake on lid open, and if i sleep, i cannot restart well as well as shutdown, there is no video but there is still activity on the wifi, fans and power monitor.

thanks to mormegil. my laptop now goes to sleep when i close lid. just an issue: now the restart and shutdown processes have become slow (the system remains blocked on the desktop for 10 seconds doing nothing, and then it restart). i don't know why. has anyone the same problem?

Try to add the PNLF section on your DSDT, it works for me for sleep (no wake) but I avoid the ugly Notify to the SleepButton.

i tried the sleep fix, but i can't get it to work, sleep in general doesn't work, when i press the sleep button, my screen freezes and that's all, when i press the powerbutton i get the restart/shutdown popup and all works again.

Lidsleep also does the same, screen freezes but stays on.

i wanna ask you if you plz wanna look at it?
