Having problems with your Dell PC Laptops ?

I have a dell latitude c400 my screen is dim. However I am able to use an external monitor.

If the screen is dim and and external monitor works, then the LCD backlight has failed. Replacement LCDs for that model are around $100 on Ebay and take 30 minutes to an hour to install depending on your skill level
