Sleep/Wake on Asrock Z77 PRO4

5 posts in this topic

Recommended Posts

Hi,

 

I have all of my hardware (on my sig) working almost perfectly, what I do not have working is sleep/wake. 

 

When setting the computer to sleep, the screen goes black but the computer fans stay spinning. If comes of this "sleep" just fine. From what I've read it this might be fixable using a DSDT.

 

The thing is I do not know if it is possible to use a DSDT with Clover or how to "create" one. Although I'm not computer illiterate I'm a little afraid of ruining my currently pretty nice system. 

 

Can I enable sleep/wake without the need of DSDT and using a kext instead?

 

I currently have this BIOS flashed: http://biosrepo.wordpress.com/asrock/z77/

 

Can someone shed me some lights?

 

Thanks in advance to all the community that's been so helpful since the beginning.

Hi poispois,

 

I have the same motherboard, but with i5-3570k, no GPU card, using Intel HD4000.

Sleep works properly in 10.8.5, all fans stop spinning.

 

I am using my own patched BIOS since biosrepo hasn't updated to the latest ASRock BIOS version.

More info: http://biosrepo.wordpress.com/2013/01/19/simple-way-to-patch-your-own-bios/

 

Even though I am not using Clover, I am quite sure it supports user provided DSDT.

The easiest way to create one is with MacIASL using pjalm repositories:

Add these repositories to MacIASL (guides):

http://pjalm.info/repos/asrock/

http://pjalm.info/repos/graphics/

 

Create your DSDT (read NOTE at the bottom of the guide before starting):

http://pjalm.info/creating_a_dsdt.php

In your case select Z77 PRO4 first, click apply, then select nVidia/ATI, click apply.

 

Also, in my chameleon.org.boot.plist, I have the following switches - try to find Clover alternatives:

darkwake=0 EthernetBuiltIn=Yes USBBusFix=Yes

 

You also might want to create your own SSDT tables for better speedstepping and power management.

Combined with DropSSDT=Yes in chameleon.org.boot.plist and Macmini6,2 smbios I get the best performance of all combinations.

 

Hope this helps.

My differences from you are that I have both ethernet and wifi working apart from the GPU.

 

Do you use a DSDT or is the BIOS sufficient for sleep/wake functionality?

 

I've searched in S/L/E and I don't have NullCPUPowerManagement.kext is this right?

 

I've also read that there is a SleepEnabler fix but i'm afraid my boot can get corrupted somehow.

 

Thanks for the help.

I have a WiFi card too that is recognised as an Airport card. I also have a firewire controller and another e-sata controller plugged in. It all works nice.

 

I am not sure if sleep works without DSDT, haven't even tried since I just copied my working DSDT and SSDT when I installed ML.

 

If you have flashed the patched BIOS, you can use native AppleIntelCPUPowerManagement.kext without the need for NullCPUPowerManagement.kext. Apart from this and DSDT edits, there is no other SleepEnabler trick that I know of.

 

It should be quite painless to try the method I suggested. You are not going to mess with system files - only DSDT, SSDT and boot switches. If your machine doesn't boot, you can easily revert changes.

 

Maybe you can install Chameleon alongside Clover and boot it with key '1' so you don't mess up your Clover config.

      I am a novice in the field of Hackintosh, and this is my first post here.
       
      I have managed to setup and install my hackintosh and it is perfectly working other than this one issue.
      I am unable to figure the exact cause of this issue. My Hackintosh is unable to go into sleep mode after the set time. This is what happens (see the attached video file).
       
       

      mojavesleep.mp4  
      You can see that the screen turns off, then I see the power on the graphics card and fans turn off.
      Immediately it comes back ON and the screen TURN's ON.
       
      I have followed various threads in several forums trying various options suggested for sleep related issue, but have been un-successful.
      If anyone is able to guide me through in resolving this issue, I would appreciate that.
       
      I am unsure what files need to be attached for you people to help me, feel free to ask and I shall upload the necessary files.

      Hi,
       
      I have High Sierra 10.13.6 installed on a Gigabyte h360m d3h, an i3 8100 processor and a GeForce GTX 760.
       
      I'm having some issues with sleep, shutdown and reboot not working correctly, this is what happens:
      Sleep: the machine restarts
      Shutdown: the OS appears to not be running but the machine is left on
      Restart: the same as shutdown
       
      Everything else (audio, video, usb) appears to be working correctly.
       
      Do you know how can I fix this?
       
      I'm attaching my config.plist and clover bootlog
       
      config.plist
      bootlog.txt

      The display sleep does not work correctly. Starting with Mac 10.12.4, the display sometimes does not wake up. The backlight works, there is no image, a black screen. Currently installed 10.14.1. All the same. If the display is sent to sleep, then sometimes it can wake up in a black screen with a working backlight. From the description, it is not difficult to guess that the display sometimes wakes up correctly and sometimes wakes up in a black screen. In the course of the experiments, I also saw that the display sometimes woke up and showed the boot screen (the Apple logo and progress bar), a second after that the desktop appeared. This behavior occurs only when the display wakes up on a black screen and then I close and open the laptop cover again, after which the boot screen sometimes appears for a second, but sometimes nothing appears, the system just hangs.
      I hope I clearly described the symptoms of the problem.
       
       
      The screenshot was taken after the experiment. I sent the display to sleep, then woke it up. He woke up in a black image with burning lights. Then I closed and opened the laptop bucket, pressed the space bar and waited a few seconds. After a few seconds, the boot screen with the Apple logo appeared and then the desktop appeared. Immediately made a screenshot.

      Hi, my hackintosh won't sleep!
      It often sleeps for 3-5 seconds and auto wakes up.
      sometimes it can't enter the sleep mode even you click the sleep button.
      I have uploaded my DSDT file.
      but I don't know how to patch DSDT.
      If you know how to solve this issue, please help me!
       
      Cheers,
      Brian
