Product: HP ZBook 15 G4
Operating System: Microsoft Windows 10 (64-bit)
Every time when i want to wake up my laptop out of sleeping mode , the screen flickers and it is black on the screen. I think dat the computer is running normally because i hear it when i typ in my password. But the screen doesn't show me anything.
I read somewhere that i have to close and open the laptop , as a result of that i sometimes get my normal screen back.
I want this problem to completely dissappear.
Can you help me?
