Hello yoyoxide.


from my experience can be something related with the video card. I recommend you the followig (Hardware diagnostics):

-Look for one of the discs that came with your computer, it should say (Drivers & utilities).
-Boot from the CD. If you don't know how to do it do the following:
1.Insert the Drivers&Utilities Disk.
2.Restart teh computer.
3. When you get the Dell logo, press F12
4.Select Boot from CD/CDRW-DVD (something like that).
-You will get a prompt to run the diagnosics.
-Just follow the wizard
-I recommend you to run diagnostics for everything.
-You will see if you have any problems with your hardware.

It seems that you have a pretty new laptop, so probably it's under warranty.

Had the same problem. Fixed it though. Here's how:
You'll notice that the screen comes back to life if you press down on the very top of the green line. This is because a controller circuit board behind the LCD screen (at the top) is pressure fit flat-surface-to-flat surface to the contacts on the back of the LCD. Eventually, the sticky substance that holds this circuit board in place wears thin, collects dust, etc.. and the connection between the circuit board and the lcd contact is lost. The line appears where this break in contact has occured. 
So, the solution is to increase the pressure at that point to reestablish the connection. I wasn't able to remove the circuit board to clean beneath it as it seemed too likely to cause damage. Nor would I have had the right adhesive to connect it back, so I simply removed the LCD and put a bunch of tape at that point so that it would "push" with a little more pressure when screwed back into place. Worked great.
To remove the LCD, pull off the 6 feet around the screen. Remove the screws behind them. Carefully pry off bezel with a small flathead screwdriver working your way around it. Once removed there are simply 4 screws on the left and 4 more on the right of the LCD to remove. Pull out screen carefully and start stacking bits of tape on the spot where pressure seems to work best. Put it back in and see if you've made any difference. I did this with the computer on so I could verify my results. Just be careful not to short out any naked contacts.
If this doesn't work for you, at least you'll know you just need to replace the LCD, not the video card. Easily found on ebay.

Contrary to what angelo-mlc has written, this problem is nothing to do with the monitor, which is clearly working.It is a graphics problem.If the GPU IS an integrated Nvidea 8600m card, there is an issue with it. As your model has been off the market for at least a couple of years, obviously you warranty has run out.Despite that, in some countries the computer seller would still have an obligation to you if it involves an inherent defect, which in this case it does.
For example, in the UK you would be protected by the Sale of Goods Act for up to 6 years, and for the same period in Singapore which has adopted the UK Act. Some other countries have similar legislation.Remember, it is the retailer that has the obligation. Not the manufacturer..
Action in the UK would be as follows:. Get on to the retailer's customer service by phone. No need to go there..Tell them you have an 'inherent defect' and you want your money refunded.Tell them what the defect is and that it is known to have an inherent defect.Refuse any offers to repair, or examine by their techicians. Don't accept any statements saying you should refer to the computer manufacturer, or to Nvidia.You don't have to do that, and the retailer knows you don't.Ask to speak to a manager. Get the name of the person you are speaking to, and their job title.
Tell them if you don't get a refund you will take it up with Trading Standards, and if necessary,with the small claims court.You may get an offer, on the grounds that you have had use of the item, and it has depreciated. Ask them to put it in writing to you.If it is derisory,reject it in writing too. You are very likely to get an improved offer, and it will then be up to you to decide whether to accept. If you don't receive an offer at all, get the address of customer services, and make a claim in writing.Send a copy of your claim to your local Trading Standards office.(Get the address from your local council, or from public library). If you fail to get a reply, or don't receive an acceptable reply,then it is time to get pay a visit to your local Trading Standards. You could also file a case in the small claims court which is almost sure to find in your favour, and would cost the retailer a lot more than compensating you.
Note. During the course of your claim, you may be asked to produce evidence of 'inherent' fault'.You won't be asked that unless the retailer knows of the fault and is merely seeking confirmation that your machine actually has that defect.
That is quite legitimate, and you could ask any REPUTABLE repair facility to check and give you a certificate.That should cost you £30 or £40, which you can claim back from the retailer when it selles with you, because if it gets that far, it WILL settle a proven defect.
Don't forget, this procedure can only be used when 'inherent defect' is claimed. In the case of this nvidea GPU chip, the defect is well know. You can find more information about that by 'Googling'.
It worked for me and for others I know. I got £300 back. It paid for quite a good part of my new Toshiba, due to prices falling a lot over the past two and a half years.
One last thing. Forget repairs. No matter what anyone tells you, it would involve a new mother board, and then you would only finish up with the same type of graphics chip again.
Good luck.

It sounds to me like your screen has gone and needs to be replaced
