Hi everyone,
I'm running 10.12.3 on a Acer E5-575-51GG laptop (i5-6200U, 8Gx2 DDR4, BCM94352Z, Elan Trackpad, ALC255) and so far everything works, except that I get a black screen on wake.
The laptop can sleep/wake when I close/open the lid, but the screen stays blank. Backlight does seem to turn on, as some backlight bleeding is visible if in a dark room. Pressing the brightness up key didn't help. And the system is running as there are sounds when the volume keys are pressed, and I can shutdown/restart by blindly operating the top-left menu.
Please see the following kextstat and kextcache output, and patchmatic, ioreg, and clover files attached:
Thank you!
