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!
1, my hackintosh machine can sleep but just for a few seconds and the fans and HDD or some devices will start working.
2, i have tried many ways to solve this issue, such as install DSDT.aml and Patch USB limit.
Do you have any method to solve this issue?
I really want some useful advice from you!
Thanks for replying.
