After my MacBook got to sleep from alone following the system settings I could not wake it up.
It showed for less than a second the login screen after this the screen turned black and nothing happened. Backlight was still on.
Could only shutdown the system by holding the power button.
Has somebody else experienced such problems.
MacBook Pro with Retina display, macOS Sierra (10.12.3)
I have done this. Done all kinds of reset even a clean install and a visit at the genius bar where they told me that my computer has no hardware problems.
Got this problems since I installed Sierra. It seems like the problems occur much often when a display is connected.
first step is do an SMC reset.
Tried also all of this steps but with no success.
Open a Terminal Window
type sudo pmset -a hibernatemode 0
