A month ago I bought a brand new Lenovo B51-80 laptop. Since the first day I've had the same problem. After 10 minutes to an hour or more my screen Will suddenly turn Black. Not like if it's turned off. The screen is still on so it's not completely black. Very dark greyish blue. The only way to get around this is by restarting using the power button.
It also happens when I'm not doing anything, so it can't be heat related. Though it's on high performance mode and no sleeping. But it also happens without those adjustments.
First time it happened where after upgrading to windows 10. Then I downgraded back to windows 7 because of latency issues. It fixed the latency, but it still had the other problem.
I couldn't find any matching problems online similar to mine. The closest one being related to overheating. But my laptop rarely goes hot.
I'm afraid it might be a hardware issue.
Someone having any idea about what is going on?
Any help appreciated!
