bottom. To change the angle of the keyboard, turn it over

6 Connecting the Mouse
Your computer has an auxiliary port for an IBM PS/2 compatible
mouse that uses a miniature DIN (6-pin) connector.
If you have purchased a mouse with this type of connector, you
can connect it to the built-in port on your computer. If you have
another kind of mouse that requires a different interface port,
you need to install an option card to provide the interface. You
also need to change the settings of jumpers JP10 and JP11 inside
the computer. See Chapter 5 for instructions, or ask your dealer
for assistance.
To connect a mouse to the built-in mouse port, hold the mouse
plug so it is oriented properly with the computer socket. Insert
the plug into the appropriate socket, marked with a mouse icon,
as shown in the following illustration.
