How do i dim the screen brightness on a dell inspiron 1525 laptop

You can buy one here http://www.laptopscreenonline.com/dell-inspiron-1525-replacement-screen-laptop-lcd-1239-p.asp for £73.

You can install a generic screen and pick one up on ebay for around £60 but there is known difficulties with switching to a non-dell screen (Issues with brightness) so it is always best to stick to genuine Dell screens.

Hope this helps

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

This is one of the worst sorts of failures darling.

download the driver from this link and specify the what OS are you using.

Hello,
Please connect your laptop to an external monitor and see if the output is the same. If it displays fine on the monitor, then we are looking at either a screen cable problem or a screen problem. If the display is the same as on the laptop, then it is a problem with the display adapter on the mother board.

All the best.

Sometimes the brightness is on the arrow keys hit the Fn or function key and press down on the arrow to dim the light or press up on the arrow key to increase brightness

If you're using the battery, change the power saving settings.

you can try adjusting the screen brightness manually by pressing the blue FN key plus the up/down arrow keys. brighter is FN+UP ARROW. if you have a program called quickset open that and there should be an option under power options/settings. if neither of those solutions fixes the problem then the problem is the screen. a geek squad (1-800-geek-squad) will repair or replace the screen for you. thank you for using fixya!

You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the 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.
• 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 it up, 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.

try using the fn key and the brightness keys at the top of keyboard
