[solved] Black screen after waking up

[Mocha7]

I have the same problem now. It only happens when I leave it to "sleep" longer (tested a couple times, the shortest time was around 30 minutes). If I put it to sleep for only a few minutes, it's fine. Kindly advise. Thanks.

USB WiFi is known to cause instability, especially with sleep.

Test sleep without the USB WiFi device plugged in.

Note: ACPI is not patched correctly. See guide: http://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

Tested twice (30 mins each time) without USB wifi and you are definitely right! Thanks again RehabMan!

I still have truevision HD camera and HDMI audio left to conquer. Did you get your camera to work?

After camera and HDMI audio fix, don't know why the sleep is gone...now even I put it to sleep with no usb plugged in, it's dark screen every time I wake it. Any input is appreciated. Thanks.

Your issue is likely caused by USB WiFi. Install supported PCIe WiFi instead.

Thanks for your reply. I ordered the AR9285/AR3011 and still waiting for it to arrive (if I read your faq earlier I will go with AR9280). I will test and report later.

I installed a BCM94352HMB and removed the usb wifi, no luck. So I reinstalled OS X and re-did the DSDT patches and installed battery, backlight, ethernet, pcie-wifi, AppleHDA and HDMI audio kexts, still no luck. Everything works but black screen after wake.

ACPI is not patched correctly. Based on ACPI/origin, you should have in ACPI/patched:
DSDT.aml
SSDT.aml (from ssdtPRgen.sh)
SSDT-0.aml
SSDT-1.aml
SSDT-2.aml

Also, DropOem=true is required when you have patched SSDTs in ACPI/patched.


Also, use just "Brightness Fix" + IntelBacklight.kext.

Thanks for your help! Still wake to black screen. It might be just my machine doesn't like me.
