This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

It sounds like there is physical damage to the keyboard. You'll need to replace it. Laptop keyboards are actually quite easy to replace, but finding the part might be tricky. Looking around on eBay is probably your best bet.

If i get an External Keyboard , How can i disable the inbuilt laptop keyboard – sam May 21 '11 at 6:39
Your BIOS may have an option to do this, but it is not guaranteed. I'm not sure of any good way to do that, because Windows will automatically connect to and load any human input devices it finds. – jcrawfordor May 21 '11 at 6:45
Ok i'll see to that – sam May 21 '11 at 6:55

Depending on your model, replacement keyboards can be quite cheap and they are easy to replace. Go onto the HP support website, enter your laptop model number and download the maintenance and servicing guide, in there you will find instructions with pictures/diagrams on how to replace the keyboard. It is a very straightforward and simple procedure.

If you do decide to go with an external keyboard, you might be able to get away with disconnecting the inbuilt keyboard and pointing stick cables to disable the keyboard.
