Did you spill coffee on your notebook? or dropped cigarette?  or pound it so hard in frustration that the key broke?
We've seen them all. Replacing the keyboard is a fairly inexpensive thing.

Please call ahead to make sure we have the correct keyboard in stock.  We'd need the exact make and model of your notebook computer.

We replace keyboards for Toshiba, HP/Compaq and Dell brand notebooks.

A good test for you to perform is see if the computer works fine with an external USB keyboard attached.
