The Keyboard, pointing device, and display are in many ways the most important parts of a computer because they represent the human interface to the system.Unlike desktop systems, portables have keyboards intergrated into the one-piece unit. This makes them much more difficult to repair or replace, and you can’t switch keyboard models or types; you are stuck with the model that comes with the system. Because you can’t switch the built-in keyboard, the keyboard should be an important element of your system-purchasing decision when selecting a new laptop. Because manufactures are forced to modifify the standard 101-key desktop keyboard layout to fit in a smaller case, you’ll find a variety of different laylouts as well as significant differences in keybutton travel and feel among units.

Here are some tips and tricks for troubleshooting and fixing your Dell Laptop’s video problems. Video issues are very common within Dell notebook computers and with the following tips you should be able to detect and eliminate basic laptop video problems.

Dell Laptop LCD screen has a faint image or is very dark:

Look closely at your Dell Laptop‘s LCD screen, and see if you can see a very faint image. If you can then it is possible that the Laptop’s LCD lid close switch is stuck in the closed position. In this mode the backlight stays off, even with the LCD lid open. This is to conserve power when the laptop is ON with the LID closed. Check the LCD lid close switch. It is a small plastic pin located close to the back LCD hinges. Try tapping the lid switch a few times to see if you can turn on the screen backlight. If that does not help, then I would suggest to replace the FL inverter board.
