Press the Fn key and the up arrow key simultaneiously, this should increase the brightness. (down arrow key reduces the brightness)

If this does not increase or decrease the brightness, then the problem should be with the backlight or the backlight circuits. Please contact Dell for a replacement of the LCD panel (if your computer is in warranty) if not contact a local tech who can replace the LCD panel or the Backlight for your laptop

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.

press; Fn+ up the screen should go brighter!

It's a faulty backlight (screen).
Replace screen (same dell part number) with inverter, otherwise screen can be dark.
Here is how Dell part number looks (green):

This could be a faulty video cable or connector or CCFL lamp or inverter.
Try reseating the video cable/connector that connects to the motherboard first.
If this doesn't work then 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.

ok , i have had this problem on bolth my dell inspiron laptops , on a 6400 and a 1525 . the 6400 had the lower left corner all dark and the 1525 was split right down the center . i fix bolth of em in a really simple way , turn on ur pc and go into windows , press the blue Fn button and the down arrow untill ur brightness from ur backlight is completely down . keep it that way with the screen on with a screen saver for about one hour then turn brightness back up but not all the way up cuz in my case the problem hapened again , but when i keep it just one click darker , boom problem fixed . from what i can figuere out is that the inverter aint powerfull enought to power the backlight and tends to over heat , so keeping the backlight a bit lower tend the keep em ok

I would suggest connecting the laptop to an external monitor, just to make sure that it is all running correctly.

If you can see a very dim image on the screen then the backlight is out. This can be a light problem or the inverter that powers the backlight could be bad. The inverter is not real dificult to change and also is not very expensive. If it is the backlight tho, it is easier to just change out the entire screen.

Hope this helps
