I have a Toshiba laptop running Windows 7.

For some reason I'm unable to type the letter Z or use any of the arrow keys. If I insert an external keyboard then it works fine.

What is wrong? How can I fix my laptop keyboard?

The keyboard is broken. Most likely due to something spilled on it. Sometimes you can disassemble things and wash the keyboard to recover from this (I did a long post on this topic maybe a year back), but the odds are against it. – Daniel R Hicks Jan 3 '12 at 12:39

It could be that your laptop keyboard is broken, if an external keyboard is working okay.
Are the z and arrow keys feeling okay when you press them?
If they don't feel good you can be sure it is broken.

Changing a laptop keyboard is quite expensive, unless you have insurance.

Yes, for the external keyboard it respond well. The problem is on the laptop keyboard only. – Ngorodinho Jan 3 '12 at 11:04
