Switching Key Functions on the Internal Keypad

You can temporarily switch the functions of keys on the internal keypad between their standard keyboard functions and their keypad functions by using the Fn key or the Fn+shift key combination.

■To change the functions of a keypad key to keypad functions while the keypad is off, press and hold the Fn key while pressing the keypad key.

■To use the keypad keys temporarily as standard keys while the keypad is on:

❏Press and hold the Fn key to type in lowercase.

❏Press and hold Fn+shift to type in uppercase.

When the Fn key is released, the keypad keys return to their keypad functions.

Most keys on most external keypads function differently when num lock mode is on than when num lock mode is off. For example:

■When num lock mode is on, most keypad keys type numbers.

■When num lock mode is off, most keypad keys function like arrow, page up, or page down keys.

When num lock mode on an external keypad is turned on, the num lock light on the notebook turns on. When num lock mode on an external keypad is turned off, the num lock light on the notebook turns off. The num lock light on the notebook also turns on when the internal keypad is on.

If the external keypad is connected to the PS/2 connector on an optional port replicator, the internal keypad cannot be turned on. If the external keypad is connected through a connector other than a PS/2 connector, turning off num lock on the external keypad also turns off the internal keypad.
