Press the Num Lock key.If you have a separate numeric keypad on your keyboard, the Num Lock key is located in the numeric keypad. If you’re using a portable computer, the Num Lock is a function key, marked Num Lock (F6). If your keyboard has a separate keypad but no Num Lock key, try pressing Shift-Clear.
If the numeric keypad still doesn’t work as you expect, you may have enabled Mouse Keys, which lets you move the pointer with the keypad.To find the option that turns off Mouse Keys, choose Apple menu > System Preferences, click Universal Access, and then click “Mouse & Trackpad.”
Most portable computers have a group of keys on the keyboard that can function as the numeric keypad. To find the keypad, look for small numbers or symbols in the lower-right corner of keys on the right side of your keyboard. Press the Num Lock key (F6) to turn on the keypad. The green light glows on the Num Lock key when the keypad is active.
- If the Mouse Keys function is turned on, you can disable in two ways. The fastest way is to press the alt/option key five times. If that doesn’t work, follow these steps:
1. Go to System Preferences.
2. Select Universal Access.
3. Switch to mouse view.
4. Turn the Mouse Keys off.
- If it is something that cannot be solved, you may need to contact an Apple Store retailer to replace your keyboard.
