Hi i have dell laptop xpsm1210 the Computer worked and then the screen work also but ... My computer screen is blank. and like no light on ?? so whats wrong ???

1. Restart the computer.
2. As the computer boots, press <F12>
3. when the Dell Splash Screen appears.
4. At the One Time Boot menu, press the <Down> arrow key to highlight Diagnostics and press <enter>
5. A graphical menu listing all discovered devices in the system is now displayed and the express diagnostics should run (Takes about 4 minutes).

This will test the hardware on your computer.
I am thinking it could be the battery but this is just to be sure.

Hi, Do this test for me. Turn laptop on. Get a flashlight and shine in on screen check for start screen. If there is life in. Then you know it is a screen problem. LCD light problem. If you are computer and electronic savy remove and or disasemble screen. If you are not take it to someone who can and repair.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

farooq473, replace the Inverter.

1) An LCD screen cannot produce enough light by itself. A Backlight is used to help provide the needed light.

2) An Inverter is used to provide power for the LCD screen, and the Backlight.

An Inverter boosts power up for the LCD screen, and lowers it for the Backlight.
90 percent of the time a bad Inverter is the problem.
A Backlight usually goes out all at once, Inverters slowly 'die'.

In the list click on > Display
Now click on Display Panel.

Dell doesn't show, and describe how to replace the Inverter.
When you click on Display Panel, you are looking at an exploded photo showing the Display Panel removed.
Scroll down to the next small illustration.
Has 1, 2, 3, 4, and 5 pointing to the Display Panel.

5 shows you a pull tab to release a flat cable from the Inverter. The Inverter is the small circuit board to the left of the pull tab.

This is not advertising for this website. Just an example to show you what the Inverter circuit board looks like.

This is Not a Dell XPS 1210 Notebook PC. It is a guide for replacing an Inverter in a Dell Inspiron 1525 Notebook PC, but I wanted you to have photos, and instructions for the basic procedure.
After you have repaired over 100 laptops, you'll realize that they all have the same basic procedures.
Just different parts.

3) Be SURE ALL power is removed from the laptop before you start.
Remove the AC adapter (Charger) and Battery.

4) You should follow Anti-Static Precautions implicitly. It would be best if you bought, and wore an ESD wrist strap. (Electro Static Discharge) Connect the alligator clip to a good ground source.
(For example, I connect to the metal frame of an empty desktop computer case)

The cost averages from $3 to $12.
A $3 ESD wrist strap will do just fine.
This is an example of an ESD wrist strap,

5) Use a multi-compartment container for the various screws you will remove.
Label each container for the area the screws came out of.
You DO NOT want to mix them up!

You can use a clean egg carton in a pinch. Label each egg holder.

Have questions post in a Comment.

The easy way is replace the entire screen up assembly. Here is one at a decent price

Instructions are here

Borrow a monitor and plug it into the side of the notebook to verify that the computer still works. If it does then the screen has gone out.

Dear,
This is a clear hard drive issue. Try reinstalling Operating System, If it fails again, probably you have to replace the hard drive

Try reinstalling the driver for the WEBcam/mic

Hi,

Have you installed any application/program prior to the blue screen? Most blue screen causes your system not to boot to your operating system anymore. It is possible that your hard drive is crashed due to a virus infections or spywares. Incompatibility and corrupted system registry may affect your system to have blue screen as well.

You may try the following steps below.

1. Restart your computer. After you pressed the power button to restart. Keep on tapping F8 key on the keyboard on and off.

2. Boot advanced option will show up on the screen. You may boot your computer to the following option.

a. Last known good configuration
b. Safe mode with Networking.

If Safe mode w/networking works, restore your computer to an earlier using the system restore features.

Keep me posted.

Regards,

jeff
