• There appears to be a shortage in one of your lines to you computer. But, before you replace anything, try these methods.

• Shut down the computer.

• Remove any CDs, DVDs or external storage devices (like USB keys or external hard drives) from the computer, if any are present, then press the power button to turn the computer on.

• Press and hold the <F8> key as your computer starts. You need to press <F8> before the Windows logo appears.

• If the Windows logo appears, and the system still fails to boot to Windows, shut down the computer and try again.

• From the Advanced Boot Options menu, use the arrow keys to highlight Repair Your Computer, then press <ENTER>.

• Click to select your language, and then click NEXT.

• Log in as a user with administrative rights, and click OK.

• From the Choose a recovery tool menu, click Startup Repair .

The LCD backlight is most likely faulty. If you look at the LCD screen to one side you could see a slight video image, provided the video card is working. To check if the video card is working connect the laptop's video output connector to an external monitor and then boot up your laptop. If you get an image on the monitor, then the problem is with the laptop's LCD display.
As I stated it could be the backlight or a faulty invertot that powers the backlight or it could be the cable/s that connects the LCD to the motherboard.
Try reseating these cables (requires dismantling the laptop).
If this doesn't work then you have a faulty LCD and needs to be replaced. Alternately if cost is too expensive, just use the laptop with an external monitor.

If this laptop is only a few monthe old, then it should be still under warranty. I suggest you return it to the supplier for repair or replacement under warranty. If you try to repair it, most likely you wil void your warranty.

If you don't have this choice then read the following info.
You most likely have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Hi,

It seems there is a heat related issue on your laptop. I would suggest to run first the diagnostic test, to check for hardware problem.

Try removing any external devices first (Ex. USB devices) then run some diagnostic test:

1. Turn on computer
2. Tap F12 continuously on the Dell logo screen
3. Select Diagnostics
4. Follow on screen instructions
4. Wait for the test results (approximately 10-15min.)

If all test passed no problems have been found, it means there is no problem with hardware/computer. The problem is now pointing out to be software problem. Re-installing windows will fix the problem. Hope this helps
