Gateway Laptop Screen Blank

I have had my Gateway laptop since 2007 and recently I went to go and turn it on and the screen is blank and it doesn't show anything on the screen, not even the gateway logo. I thought that maybe it was the battery so I replaced it and it's still doing the same thing. What should I do?

Does the computer still turn on? Or is it only the screen?

It turns on and the screen is still black. But the laptop sounds like it is in standby mode...

Hello,

So can still hear the fans and everything else moving/spinning?

Only possibility I can think of is that your screen is spoiled.

I have a Toshiba and when i turn it on the screen is black but the lights are on
