Laptop Display Not Working

My laptop display stopped working this morning. I had loaded up a new game (Rift Beta) and alt-tabbed out to browse around the internet for a bit. When I clicked back into the game, it loaded up the main menu screen then went to a BSOD. I shut it off for a few minutes, and when I booted it back up I can see the power coming on, but the screen stays completely dark as if the power is off.

I was able to plug in an external monitor with a VGA cable and get a picture on that, but there are all sorts of dots and lines all over the screen even during the boot up process. First boot up went through the process normally, then after the Windows loading screen it went to a BSOD as well. I had to go in and tell it to load up in VGA mode (haven't tried safe mode yet, not sure if it will be of any use) to get to the actual desktop. I then tried to set it to the monitor's native resolution, which caused a BSOD as well.

I booted it back into VGA mode (which loads up at lowest possible resolution), managed to go download the latest drivers and installed them, but to no avail. Display still stays dark when just booting up the laptop, and when using the monitor there are still the same lines/dots, and changing the resolution when using the monitor still causes a BSOD.

I finally went into the BIOS and disabled the discrete graphics, and it booted up fine using the integrated graphics. I'm typing this on the laptop without the monitor plugged in, display is working fine. I'm no expert with computers, but I fear this means my graphics card is fried. The support website for the laptop is of no help at all, and with nowhere else to turn I come here to ask if anyone has any other ideas, since I'd prefer not to have to send this thing in for several weeks for repairs. At the very least it would be nice if there was a sure fire way to know the graphics card is the problem.

System Specs:

Windows XP Pro 32 Bit
Intel Core 2 Duo T9600 2.8GHz
4GB RAM (yes, I know its not being fully utilized on 32 bit XP)
ATI Mobility Radeon FireGL V5700

Nothing is overclocked, laptop is kept in an open area with plenty of breathing room. Felt no heat from any part of the laptop at the time the initial BSOD happened.

Sounds like a bad GPU or GPU memory, which usually would mean new mobo on a laptop.

I'm guessing no warranty left?

Did you check Device Manager? I'd try uninstall and then re-install latest driver for the discreet GPU.

I have tried that.

The motherboard has integrated graphics which are working fine. Theres also a discrete graphics card (ATI Mobility Radeon FireGL V5700) which seems to be the problem. Would I really need a new mobo or just a new graphics card?

It is under warranty, but I'm trying to avoid having to ship it to them for repairs and losing access to it for several weeks.

The problem appears physical at this point so at the very least you would have to take apart the laptop and reseat the video card and replace the thermal pad/paste to see if that would fix it. But it sounds like your dedicated GPU is toast so it would be best to send it in for warranty repair. Maybe you can use onboard until you can find a loaner.

Do you have a Lenovo? Talk to them about just shipping the card if it's replaceable.

Oh sorry, I missed that part in your post - I jumped to your specs and didn't see anything mentioning integrated. Yeah I would re-seat the discreet card to see if that fixes it. If not, then yeah a new card would probably do it.

This is assuming that your "discreet" graphics isn't actually integrated onto the motherboard, which is a possibility.

Yes it is a Lenovo. They were able to ship me a HDD replacement when that went bad, so maybe they can just ship out the graphics card as well. I'll try re-seating the card then call the manufacturer if that doesn't work.

Thanks for the help everyone, even though all you did was confirm my worst fears :p
