Problem with my laptop  

first off - have you tried shutting off the lap and turning it on again, did that make the display turn on? or is it still off?

if it's still off, looks like you have a problem with the LCD display. It can be a video subsystem problem, or a problem with the lcd itself.

either way, you'll have to take it to a repair shop, because these sorts of problems aren't user-fixable. If you have a spare monitor (CRT or LCD), and your laptop has a secondary display port, you can try plugging into that so you can continue using it, it seems to be still running, as the lights are still on. Otherwise, gotta take it in into the shop.

Hi, maean_19. I am no laptop expert, but when I was typing a while ago, I went to submit my post and when I did, the screen went to another page about me being banned. So, I just went back up to my browser and resubmitted my post again and it went through. One time I had to write my post all over again because my page just disappeared. It was very strange. I don't like having problems like this. I hope that you won't have anymore of your own either. It could be a glitch in the system, I hope.

same as my laptop. go on your netbook service centre my friends

Reset your bios setup to default that may do the trick. I could only see two reason why it turn black first the video card over heat so if your vga is nvidia supported it may nit shutdown but instead our screen will, if it is radeon or ATI then that is what you will see it will automatically shutdown or visual monitor but not the laptop itself. Second is that your computer hybernate automatically. All you need to do is turn it off and on again. Or you it may be the third reason your RAM has passed out check if it is your ram support 2 slot try to remove one after another.

i never had a problem like this with my laptop so far and i am thankful for that. what i experienced lately with my desktop, a blue screen made the windows disappear and i never bothered to check what went wrong. there said that i just need to restart my system if the same problem occurs, so i just restart the system and everything went back to normal.

Hey did you try restarting the laptop? Did it come back with the same no video problem?

Did you try turning it on without the battery, just the AC?

When you turn it on, do you hear the windows log on sound? Did you make sure that it was really no display or just a dimmed lcd?

There are a lot of factors and things to check to be able to ID the possible issue. However, if these things still did not help you diagnose what the problem was, take the laptop to the nearest repair center. It seems that either you have an LCD issue, or a video card issue. They will be the best to diagnose what the problem is. :)
