Exclamation Alienware M9700i R1 laptop- black screen

So i recently got a nice Alienware laptop (maybe 6 or 7 years old) from my brother he said it had no video. I thought it would be easy to fix but i have checked everything, but i cant get anything on the screen at all. Is the video card dead. If so where do i order one. I don't know what else to do.

Out of my knowledge set but does it have a video out connection? If so try with an external monitor. If it works with a monitor then it probably isn't the video card.

Tap F8 as soon as you boot the machine. Continue to tap it until you get to a menu. Choose VGA mode. If you get to the desktop, it's the video card. If you don't get to the desktop, it's the motherboard.

Donoli, if the video card is bad (and no onboard video) how would he see anything. If he saw nothing how would he know if it was a video card or a bad screen or a bad backlight or inverter. Not my area but your answer seems flawed and over simplified.

I tried to connect it to an external monitor but i got nothing.

So, let me guess its the GFX card? or is there other things i can check. I can replace the graphics card myself. I worked at a computer repair shop for about 2 years. And i have replaced them before i am just not very good at diagnosing stuff.

If you boot into safe mode it bypasses the graphics card and goes to the basic VGA so you can troubleshoot. I limped along a laptop for years in safe mode with networking. Continue to tap F8 until you get to the choice screen. Several laptops had motherboards that tended to overheat and it messed up the graphics chip by releasing the solder bonds. Look into "reflowing" the graphics chip. If you get it working, a cooling fan is a must. I have one that has 5 fans on it.

Further...

It also may be the led back light. Try to turn it on and hold a strong flash really close to the screen and see if you can see the ghost image of your screen working. If so, it is the back light and can be repaired.

That's exactly what I was trying to say.

And I wrote: "and no onboard video". Use to desktops where you have to do that through bios and OSes that don't as far as I know recognize F8. Thanks for the correction.

Nothing, the liquid crystal itself is like that greenish black color you get when a laptop is turned off. I tried pushing F8. I also noticed that if i just let it boot the Windows (Vista?) startup sound plays. So as far as i know video is the only problem.

You can't just press F8 once & expect it to do anything. You need to get to that menu before you do anything else.

Did you hold a flashlight up to and TOUCHING the screen to see if you can see anything? Just looking at it will not show the individual LED pixels. I mean it will be the ever so faint ghost image. Move it around until you see an object.

For what its worth at this stage. When my graphic card went the screen took on a halo effect where there was light, dark, color and a wash of brightness that randomly roamed the screen. When my back light went out, it was a total black screen.

While you had it running, did you scan the file system or do anything else? If not, why not?
