Still got black screen after grub boot, event with 4.9 rc-7.
Sometime I have time to play around for 5 minutes, sometime it turns black almost immediately. The screen is still powered on and laptop still running, just plain black image.

Sometimes, when it turns black, it's like I can see the image drop down the screen in a fraction of a second.

Kernel 4.9rc7 seems very stable after it boots up. But overheats a lot and
booting up often takes several attempts.
