Question about Computers & Internet
First to make sure the controller is fine use an external USB keyboard. Open notepad and try all the keys.
now without closing notepad using the internal keyboard and try the keys that so far don't work. Still a problem, turn off laptop.
carefully lift the key cap and see is there is some dust hair or something that is preventing the key to react well.
Last if you can get a live DVD/CD from Linux and try to open a similar notepad program and try the keys. if all work your laptop windows could be infected or corrupted.

First thing to try is re-securing the keyboard ribbon on the motherboard. to do that on most dells its as simple as popping off the top strip where the power button is and then remove the screw holding the keyboard down and carefully pull the keyboard away till you are able to pull the retaining clip up and remove the ribbon from the motherboard. then reinsert it securely and push the retaining clip down. sometimes there are screws on the underside of the laptop that hold the keyboard on but ive never come across a dell that does that personally.
If re-securing the ribbon doesnt do the trick, then you are better off buying a keyboard off of ebay(usually between 15 and 20 dollars) than messing with the insides of the keyboard. good luck.

Sounds like your number lock is on. Find the key with blue lettering that says 'Num Lk' (or something very similar). Press Fn and that key, and your number lock will be turned off and your keys will go back to normal.
Hope this helps.

if you go to the control panel, to hardware, in the keyboard section you should be able to uninstall the internal keyboards driver which will stop it working.

You might be able to find a cheap replacement palm rest (which includes the touch pad) on E-Bay or similar site. Just search your model number.
As far as replacing it yourself, I recommend having someone that works on computers regularly doing it, unless you are completely comfortable working inside the laptop. If you are (and you take all necessary precautions), here is the Service Manual from Dell which includes disassembly instructions for the palm rest.

Testimonial: "This was much better information than I expected to receive."
There isn't any "Known Issues" that I am aware of with that model. Try re-seating the keyboard cable, see if there is any difference:
If no difference, contact Dell if under warranty. If not new keyboards are about $20 on EBay

Tips for a great answer:
On most laptops there is a function key that will lock the keyboard.
You would need to pres the [Fn] key and the appropriate [F#] key. In mine the combination
would be [Fn+F1] keys. If you shut down to re-activate the keyboard you will loose whatever you are working on.
hope this helps
