Using an External Numeric Keypad
The embedded numeric keypad cannot be used while an
optional external numeric keypad is connected to the notebook.
Most keys on most external numeric keypads function differently
depending on whether hum lock mode is on or off. For example:
• When hum lock mode is on, most keypad keys type numbers.
• When hum lock mode is off, most keypad keys function like
the arrow, page up, or page down keys.
Turning Num Lock Mode On and Off
As You Work
To turn num lock mode on or off on an external numeric keypad
as you work, press the hum Ik key on the external keypad, not on
the notebook.
When an external numeric keypad is turned on and is in hum
lock mode, the hum lock light on the notebook is on.
When an external numeric keypad is turned off or is turned on
with num lock mode turned off, the num lock light on the
notebook is off.
