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.

Laptop keyboards are cheap; order a new one. – Ignacio Vazquez-Abrams Aug 14 '12 at 19:08
Have you recently spilt anything on the keyboard? – Mokubai Aug 14 '12 at 19:11

Could be a bad connection, or more likely, something got stuck inside of it (maybe something sticky, like sugared soda?) and is causing the issue you are having now.

If you are comfortable with doing hardware repair, I would recommend disassembling your laptop to the point that you can remove the ribbon cable connecting the keyboard to the main board, and reseat it. Baring that, I would recommend purchasing and installing a replacement keyboard, or taking it to a qualified service technician in your area and having them replace the keyboard.

If this is urgent, don't waste your time waiting for the best answer here.

Try these things;

  1. Use canned air to blow any debris from under the keys. I have seen pieces of food cause similar issues.
  2. Plug a standard keyboard into the PS2 or USB slot to get you by until you can replace the keyboard.
  3. Take it to a technician who can troubleshoot the problem and repair it if needed.
