I am on a mac Mini, and I have bootcamp installed with XP. when I am in Leopard the number pad works, but when I am booted into XP it does not. The keyboard is a wired apple keyboard, the white one not the alluminum. if anyone has any ideas to fix this it would be appreciated.
I struggled with this one for a bit. I chanced across the solution on another form, and I didn't take note of the person who posted the answer to this problem. However, the solution is obvious once you read it (particularly if you have worked with PCs before).
As a default, the Numeric Keypad on a PC Keyboard is not active for number entry. To activate the Numeric Keypad on a PC Keyboard for number entry, you must first hit the NUM LOCK button. Once you hit the NUM LOCK button on a PC Keyboard, the numeric keypad becomes active and ready for number input (the Numeric Keypad's default mode is to act as cursor arrow keys for moving the cursur around when the Num Lock key is not active, with the number 8 an up arrow, 2 a down arrow, 4 a left arrow and 6 a right arrow - precisely what the Numeric Keypad on Apple's Extended Keyboard does).
So how do you activate NUM LOCK on Apple's Extended Keyboard?
The Apple Extended Keyboard doesn't have a Num Lock key. However, by tapping the CLEAR key (located near the top left side of the Numeric Keypad on Apple's Extended Keyboard), you activate NUM LOOK, just like on a PC keyboard.
That is, toggling the CLEAR key will activate Apple's Extended Keyboard's Numeric Keypad on and off, just like the NUM LOCK key does on a PC Keyboard.
I hope this helps.
