I have a Dell latitude laptop. It has worked great however this morning would not boot up I get a light but only a grey screen..... HELP.... all my work is on it and it can't die. It is less than a year old.
Please give step by step help if you can as although I use a computer regularly I have never trouble shot one.
What model of latitude is it???
try a diagnostics first
To launch the PSA diagnostics, perform the following steps:
Press and hold the <Fn> key, and then press the power button to power the system on.
Release both buttons.
The PSA diagnostics sequence begins. After approximately 30 seconds, the computer emits a number of alert tones. After the alert tones, the computer emits a series of low beeps.
Record the sequence of beeps in the log.
Check for no video while the system emits beep codes.

Lightly tap the LCD back plastics (top plastics).
Gently apply pressure on the bezel surrounding the screen.

If the lcd screen is affested by movement then you need to reseat the lcd cable.
If that fails try these steps: this will check to see if the suspend switch is jammed. this switch is located along the top of the plastics beside the power button
Remove the hinge cover and check the position of the suspend switch.
To remove the hinge cover, perform the following steps:

To remove the plastics you will see a small grove to the top right of the keyboard. using a screw driver ease the plastic up all the way across
Press down on the suspend switch and confirm that it is not in the down position.

Press the power button and check for POST.
Try these steps and get back if you still have a problem.
