Keyboard Keypad not working

[jb99]

iMac G5 rev.A OS 10.4.11, Original Apple Pro Keyboard

I never noticed that the numerical keypad on the RH side of my keyboard was inoperative, in that I cannot use the keys to type the digits in any text, nor for entering numbers in an Excel spreadsheet cell.
I never use it except to use the 12346789 keys to nudge the pointer. I always use, by habit I guess, the number keys above the letter keys.

I checked the Finder’s Help and did not find any specific info about the numerical keypad. I thought that may be the Extended Keyboard that came with the computer, somehow had not been identified properly when I installed OS 10.4. Reading Finder’s help about that subject, it said to “Open Preferences, Click Keyboard and Mouse, Click Keyboard, Click the “Change Keyboard Type” button, and Follow the steps when the Keyboard Setup Assistant appears.”

I have one problem: my Keyboard and Mouse Preference does not have a Change Keyboard Type button. Any suggestions as to how I can get the numerical keypad to work?

jchuzi at MacFixit fix my problem. He advised to turn off Mouse Keys in the Preference Universal Access Panel.
