Does this problem occur only when the external keyboard is attached, or does it also occur when the external keyboard is not attached?

Does the problem persist after rebooting the system without the external keyboard attached?

the laptop keyboard stopped working.   this is when the problems with the external keyboard started..   I have tried re-booting with and without the external attached.   Yet here the typing has been normal.

Remove the internal keyboard from the laptop. It probably has stuck keys, or liquid got in and is causing it not to work properly.

Possibilities:

  1. Jammed key on the keyboard.  Give each key a sharp tap and see if the problem resolves.  If this doesn't work it gets ugly.
  2. Shorted sense line on the keyboard.  Can be caused by spills.  Requires removal and replacement of the keyboard.
  3. Keyboard controller failed.  Requires removal and replacement of the keyboard.  In cases where the keyboard is "dumb", requires removal and replacement of the motherboard.

I would boot the machine from a bootable CD or Windows Installation DVD and see if the keyboard (laptops own and external) works there ok. This would exclude Windows as a possible cause of the problem.

I didn't understand your answer about whether or not the problem appears without the external keyboard attached.

If the problem does not appear then, it points to a bad external keyboard.  If it persists without the external connected then it points to a problem with the laptop keyboard.  On many models the keyboard is easy and inexpensive (less than $20) to replace.  What is the make and model of your laptop?
