Hi folks,

After buying the 550 Ti and realizing that neither graphics acceleration nor sleep/wake worked, I sent it back and exchanged it for a 560 (non TI) assuming that those things would finally work.

While graphics acceleration now works fine, I'm having trouble getting the computer to wake up after it goes to sleep. When I sleep the computer the fans, LEDs, and drives are still spinning, but the screen goes black and the keyboard and mouse are unresponsive. Pressing the volume buttons on the keyboard doesn't make any noise, so I know that the computer isn't seeing the input devices. As of yet I have no way of waking the computer up besides holding down the power button and rebooting.

Information:

Hardware:
Core i5
Zotac Nvidia 560
8GB RAM
Gigabyte GA-Z77-D3H-MVP motherboard

Software:
Mountain Lion 10.8.0
Bootloader: Chimera (I know, I know, sorry)
CUDA drivers successfully installed

Any kexts I should try to get sleep/wake? I installed the one that was supposed to support the 560 from that kext installer that supports a lot of different things... but it didn't help me.

Or could it be a BIOS issue? Is there anything I absolutely must have in the 77-series motherboard's BIOS in order to have functional sleep/wake?

Thanks in advance for any and all help.

May be stupidly simple but you have check you haven't got NullCPUPowerManagement in /S/L/E haven't you?

You may be experiencing a CMOS reset.
there is a perl patch for this, make sure you use the one for ML not Lion

No luck with that patch, same thing happened as always.

NullCPUPowerManagement.kext is present in s/l/e, but I don't believe I've ever touched it. Should I have?

NullCPUPowerManagement prevents sleep so you need to delete it. Be prepared to re-install it if you see the AppleIntelCPU... panic though

Hey, I'm seeing this issue again after having deleted both the NCPM and the AppleIntelCpu one (after experiencing intermittent kps). Which combination of kexts ought I to keep?

Edit: Also I think I deleted my NCPM.kext backup. Where can I find a new one, provided I need to reinstall it?

Hmm, I wonder if that's what's causing my computer's insomnia. myHack 3.1.2 installed ~/Extra/Extensions/NullCPUPowerManagement.kext by default and I didn't know that it prevented sleep. Was this intended to be a temporary file to be removed after everything was up and running? Once I get my backup strategy online, I'll probably try removing the file and see how things work.

Actually, no. I tried removing NullCPUPowerManagement.kext and my results were identical to what I experienced when it was installed. I've been talking about it in this thread with Taruga and eep357, so you may want to head over there for some tips.

Getting sleep to work is not a big deal for me so it's low on my fix list.

Update:

Having removed NCPM.kext and AppleIntelCPUPowerManagement.kext, the computer will go to sleep but wake up seconds after sleeping. I've tried different combinations of installing, removing, and patching AppleIntelCPU with no luck. Anyone know how to solve this issue?

Don't remove AppleIntelCPUPowerManagement.kext, patched is OK but need to also have DSDT and SSDT. Removing it does the exact same thing as having NullCPUPM installed.

to create SSDT you can follow RampageDev's directions here http://rampagedev.wo...-own-ssdt-17-2/

I have a new Gigabyte motherboard (GA-Z77M-D3H-MVP) and therefore no DSDT. Sleep used to work, but now it doesn't... :(

SSDT can be used without a DSDT

Okay, followed guide. Sleep still doesn't work. How do I know if the SSDT installation had any effect at all?

So I created, compiled, and installed the SSDT as per RevoGirl's instructions, but my Mac wouldn't boot after installing, so I deleted dsdt.aml.

"Clover" is an alternate bootloader? I'm not sure I want to replace the entire bootloader just to get my Mac sleeping.

This worked before... any other help would be appreciated, thanks.

Subbed. I can't get sleep/wake to work with my specs, and I get intermittent freezes. I dont know if its related, but computer will wake from screensaver and mouse pointer moves but system brain-dead at that point.

Update:

Posted about this on Reddit, guy said to check the console for the wake reason. Console says "Wake Reason: GLAN XHC".
Is this fixable? What's my next step?
