It's typical of when it begins to fail. It may come back, it may flicker but the end is nigh.
Call it in before the warranty runs out.
So the other night, I was using my laptop when all of a sudden the screen started flicking and then suddenly it went dark. I looked very closely and I could still see my desktop, and it still responded to mouse and keyboard, so I figured the back light had gone. Confusingly, it came back on after a restart, but only to go off again. I have no attached an external monitor, and if I change the screen resolution of the laptop screen, the light will come back on, and sometimes stays on or sometimes go out, but then if I change the resolution again, it comes right back. It also sometimes still flickers. So what on earth is going on here? Lose ribbon cable? About to die back light? Some other screen problem I've never heard of?
Also, it will turn off if I touch the screen, but I cannot get it to come back on in the same way, I have to change the resolution to and from anything to get it back.
I'm going to return it for warranty repair, but I'm afraid that they will turn it on and the screen will be fine for them, and then break for me.
