My Toshiba laptop’s screen keeps shutting off

I have a Toshiba laptop that I bought in early 2011. It’s running windows 7 64 bit. If you need any other information about the laptop, just ask and I’ll provide it.

About 1-2 months ago, the laptop’s screen shut off all of a sudden, but the computer stayed on. I turned off the computer and turned it back on again and the screen didn’t turn on but the computer turned on. The fan was also running on high. I followed some advice I got online, and I removed the battery, held the power button for 30 seconds, put the battery back in and turned the computer on. The laptop was working fine.

About a week ago, I had the same problem and I did the same thing and the laptop worked fine. A few days ago I had the same problem, did the same thing, and the laptop worked fine. A day after that, same thing.

I bought a new battery, put it into the laptop, charged up the laptop all the way, then turned it on, and after about 5 minutes (I was already logged into windows at this point) the screen shut off.

What’s going on with my laptop? Apparently it’s not a battery problem because replacing the battery didn’t fix it.

What should I do?

Jam it back in, in the dark.

Is the screen actually shut off or is the backlight dead? Make sure you're in decent light, and look at it at an angle. If you can still see stuff, it's the backlight. Get that replaced

There's nowhere I can't reach.

Technology is quickly changing the way that business persons work each day. It is significant for buyers to play a vital part in understanding arising technology trends.

This thing is sticky, and I don't like it. I don't appreciate it.
