Hello, The keyboard is connected to the mainboard via a ribbon like connector. A keyboard is actually a matrix of contacts that are linked togheter via some 5-6 lines. If one of this lines fails (broken contact, a connector that got loose) an entire area of keys will stop to work. You may recognise connector problems of such type by looking carefully at the keys that don't work. You may find that the non working keys form lines from the top to the bottom. For example if you find that the "q" key isn't working, then the "a" and "z" and "alt" may not work as well. For "w" key, the coresponding line is "S" "x" "\" and so on. In order to fix this problem you need to dissasemble the laptop and check the connection between the keyboard and the motherboard. If you have some tools (small screwdrivers mostly) and some basic knoledge about dissasembling electronic things I will assist you through the process. Please reply back if you are willing to try to fix the laptop on your own and I will guide you through the process. Otherwise, a service center may be able to dissasemble the laptop and check that connector or the keyboard for a small fee. Please reply back when you make the decision to either repair it yourself or let a service center do the job. Good luck. Bogdan.

On the back of your laptop you should find some screws holding your keyboard fixed to the body. At most dell models each screw has it's own designation noted on the casing. For keyboard screws there should be a "W" letter next to them, for casing screws a "C" and so on. In this situation you should look for the W screws and remove them. If your laptop doesn't have this type of notation, you should try to unscrew some of them to see how they look. The longest of the screws you remove are the ones that keep the keyboard attached. Try to remove those. After you finish this, on the top side (with your keyboard) you should find a plastic part of the casing just over the keyboard near the display. It houses the power on button and everything in that area. It should be removed also. Then you can reach to the keyboard and try to remove it. You will see a ribbon like connector that runs from the keyboard to the motherboard, check that one, bend it a little and check to see the results. This should help you with the problem.
If you need more informations about dissasembling the unit please reply. Sorry for I have'n posted sooner, I was supposed to be informed by email when you reply, but however that didn't happened.
Good luck.
No, the BIOS doesn't manage this sort of things. On the contrary if the BIOS detects a major problem with the keyboard it will stop booting your laptop and give an error. These problems are only hardware based, and as you may think there isn't any reason for a software component to turn off a part of your keyboard.
