Why won't the screen on my laptop turn on?

Ok, I have a HP G62-341NR Notebook and the screen won't come on. All the lights( power button, cap lock, Wi-Fi) are on but not the screen. I know it's not broken because when I opened it the locked screen popped up and I tried to type my password in but it wouldn't show that I typed anything nor would the pointer move. So I closed the screen and like 10 minutes later tried to using it again, all lights not screen. Can anyone help I need my laptop for a lot of my school work plus my iPhone and I have a lot of homework on it so really really need a solution.

Thumb drives are miracles with this, you unplug it when your done after saving so when this happens, you just buy a new laptop. Try going to like bestbuy and seeing what they can do or your local computer store.

Evening,

Is the screen working still when you first turn it on? I. E when Windows shows up.

If you connect a TV or monitor to the laptop, can you see anything on the TV / monitor? (You may need to enable this by pressing FN & F4 once connected)

Is the screen off or just very dark? If you shine a light on it can you see anything? If you can see the screen with a torch etc and it's just very dark then the backlight may have either developed a fault or be disabled.

Hope this helps

  • Why won't my iphone 4 screen turn on? My iPhone 4 screen just refuses to turn on. It went dead, so. Tried to charge it (it has been three hours now since I started charging it). When I charge it, an apple logo comes on, but nothing else. When I take it out of the charger, it goes black.
