Dell Latitude CPi A-Series User Manual page 85

On an external keyboard, the <Scroll Lock> key acts the same way as the <FN> key on the computer's
built-in keyboard (if the External Hot Key option is enabled in the System Setup program).
You can also connect an external keyboard to the C/Port APR or the C/Dock Expansion Station.
Keypad
You can attach a PS/2-compatible external numeric keypad to the computer's mini-DIN keypad connector.
NOTE: If the computer is in suspend mode or suspend-to-disk mode when you attach an external
keypad, the device is recognized immediately by the computer when it resumes normal operation.
When you attach a numeric keypad to the computer, the embedded numeric keypad is automatically
disabled. The indicators on the built-in keyboard track the operation of an external numeric keypad.
You can also connect an external keypad to the C/Port APR or C/Dock Expansion Station.
Mouse
You can attach a PS/2-compatible mouse to the computer's mini-DIN mouse connector, as shown in
4.
Figure 4. Connecting an External Mouse
NOTE: If the computer is in suspend mode or suspend-to-disk mode when you attach an external
mouse, the device is recognized immediately by the computer when it resumes normal operation.
However, programs that were already running may need to be restarted in order to recognize the
mouse.
The touch pad/mouse device drivers that Dell installed on your hard-disk drive work with a PS/2 mouse from
Dell. If you did not receive your mouse from Dell, you must install device drivers in order to use the mouse.
This software is usually included with mouse upgrade kits.
When you attach a PS/2 mouse to the computer, the touch pad is automatically disabled. If you disconnect
the mouse, you must shut down the computer or enter suspend or standby mode and then resume from it
before the touch pad is operational. If you do not do this, the touch pad resumes operation in standard PS/2
mode, which means that many of the configuration features are disabled.
