wormyrocks Posted August 17, 2012 Share Posted August 17, 2012 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.

rockinron_1 Posted August 17, 2012 Share Posted August 17, 2012 May be stupidly simple but you have check you haven't got NullCPUPowerManagement in /S/L/E haven't you? Link to comment Share on other sites More sharing options...
Foxic Posted August 17, 2012 Share Posted August 17, 2012 You may be experiencing a CMOS reset. there is a perl patch for this, make sure you use the one for ML not Lion Link to comment Share on other sites More sharing options...
wormyrocks Posted August 17, 2012 Author Share Posted August 17, 2012 Found this: http://www.osx86.net/view/3042-applertc_patched_for_mountain_lion.html Will try it when I get home. Thanks everyone. Link to comment Share on other sites More sharing options...
wormyrocks Posted August 17, 2012 Author Share Posted August 17, 2012 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? Link to comment Share on other sites More sharing options...
rockinron_1 Posted August 17, 2012 Share Posted August 17, 2012 NullCPUPowerManagement prevents sleep so you need to delete it. Be prepared to re-install it if you see the AppleIntelCPU... panic though Link to comment Share on other sites More sharing options...

wormyrocks Posted September 16, 2012 Author Share Posted September 16, 2012 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?

HazMatt Posted September 17, 2012 Share Posted September 17, 2012 NullCPUPowerManagement prevents sleep so you need to delete it. Be prepared to re-install it if you see the AppleIntelCPU... panic though 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.

wormyrocks Posted September 21, 2012 Author Share Posted September 21, 2012 Any luck? Link to comment Share on other sites More sharing options...
HazMatt Posted September 22, 2012 Share Posted September 22, 2012 Any luck? 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.

wormyrocks Posted October 13, 2012 Author Share Posted October 13, 2012 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? Link to comment Share on other sites More sharing options...
eep357 Posted October 13, 2012 Share Posted October 13, 2012 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.wordpress.com/2012/06/30/how-to-make-your-own-ssdt-17-2/ Link to comment Share on other sites More sharing options...
wormyrocks Posted October 14, 2012 Author Share Posted October 14, 2012 I have a new Gigabyte motherboard (GA-Z77M-D3H-MVP) and therefore no DSDT. Sleep used to work, but now it doesn't... Link to comment Share on other sites More sharing options...
eep357 Posted October 14, 2012 Share Posted October 14, 2012 SSDT can be used without a DSDT Link to comment Share on other sites More sharing options...
wormyrocks Posted October 14, 2012 Author Share Posted October 14, 2012 Okay, followed guide. Sleep still doesn't work. How do I know if the SSDT installation had any effect at all? Link to comment Share on other sites More sharing options...
wormyrocks Posted October 27, 2012 Author Share Posted October 27, 2012 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.

sld87 Posted October 29, 2012 Share Posted October 29, 2012 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. Link to comment Share on other sites More sharing options...
wormyrocks Posted November 14, 2012 Author Share Posted November 14, 2012 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? Link to comment Share on other sites More sharing options...
westwaerts Posted November 14, 2012 Share Posted November 14, 2012 for sleep you need: SSDT, DSDT ( also on Uefi Boards it is adviseable to have a minimal one, cause then you know, whats happening, but for the beginning try without)) IntelCPUPowermanagement and the correspondent Controller Kext working ( check with MSR Dumper if its speedstepping) on bios also a patched RTC.kext ( dont know if its needed on UEFI) ( if its rebooting instead of waking) mostly USB and Graphic Cards are preventing sleep ( look for AAPL intries in IOREG) and the magic terminal command "pmset -g assertions" may tell you something so its a deep digging materia ( and with tony´s installers, you dont see, what is installed, so problems cant be separated) Link to comment Share on other sites More sharing options...
eep357 Posted November 14, 2012 Share Posted November 14, 2012 Not sure why you deleted DSDT because of an SSDT problem, but regardless, sleep is in not possible without patched DSDT so don't bother unless you have that much resolved Link to comment Share on other sites More sharing options...
wormyrocks Posted November 24, 2012 Author Share Posted November 24, 2012 Thanks for the advice! I'm a total newbie though, or mostly so. What's the first step I should be taking? I don't have a DSDT; how should I go about generating one? What steps should I take to make it compatible once I have done so? Link to comment Share on other sites More sharing options...
eep357 Posted November 27, 2012 Share Posted November 27, 2012 you can generate a new, clean one using Chameleon Wizard or DSDTSE Link to comment Share on other sites More sharing options...
wormyrocks Posted December 20, 2012 Author Share Posted December 20, 2012 (massive bump) I generated a DSDT with a command line DSDT generator utility. What's the first step I should take to try and figure out how to get sleep working? I need pretty basic instructions... or if anyone could point me to a detailed tutorial I'd appreciate that too.

kernel_picnic Posted December 25, 2012 Share Posted December 25, 2012 As far as I know, almost all Gigabyte's Z77 ( with UEFI ) boards are able to sleep and wake out of box. So does my GA-Z77x-UD3H. I previously experienced a similar problem. I overclocked my machine, and it can sleep only once. (After wake-up, I pressed sleep and nothing happened) My solution is to disable ``CPU PLL Overvoltage'' in BIOS. Now, with my own SSDT for overclocks, my machine has many Pstates, and proper sleeping and waking-up. More background : No NCPM nor RTC/AICPM patches, no DSDT. Hope this would help Link to comment Share on other sites More sharing options...
