Dell latitude lcd screen lamp dims


It could be 3 things:

1) Windows settings:
  • Click "Start" and then "Control Panel."
  • Click "Power Options."
  • Click "Choose when to turn of the display" located in the left-hand sidebar of the Control Panel interface.
  • Set "Dim the display" to "Never" for "On battery" and "Plugged in" and then click "Save."
2) Ambient light sensor:
Some latitudes come with an ambient light sensor which automatically changes your brightness depending on ambient light. Toggle it on/off by holding down the Fn key and then pressing the Left arrow key.

3) Brightness turned down.
Latitudes all have adjustable brightness, press the Fn key plus the up/down keys to adjust. Some old latitudes have this setting on the F5/F6 keys instead of up/down. Look for blue icons that looks like lit and unlit suns.

If the above fail, your CCFL (Cold Cathode Florescent Lamp) tube in your screen is possibly going bad. They are $10-$20 on ebay and pretty easy to replace. Just search for "CCFL" on ebay and include the exact latitude model you have. All CCFL tubes use the same power, just the length matters, but people on ebay include model numbers so you can be sure it will be an exact fit with your laptop.

Replacing the CCFL is easy, you will need a phillips screw driver, and possibly a shim/flat-head screw driver, that's it. Just watch a related youtube video by searching for "how to replace ccfl latitude" for a number of good step-by-steps.

Hi There, I've been experiencing the same setback as Kenneth. My lenovo 3000 flashed off and even if I boot it, the screen is still black.How ca I fix it?./ Ty


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I assume your computer boots up, the hard disk spins and the hard disk LED light flashes.
If so then you may have a 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.

I received my Acer 4315-2004 in December of 2007, and this week was the first time I travelled with it using the battery pac. Although the icon at the bottom right said it was 100% charged the screen...


Depends on the settings in the control panel/ power options.
If everything is maxed out 45 min to an hour is it.

If you tweak it you can get up to 2 hours if it is the heavy duty 4000-4400.
