Changing the Jumper Settings
If you change your computer’s configuration or need to alter
the way it operates, you may need to change a jumper setting
inside the computer.
A jumper is a small electrical connector that controls one of
the computer’s functions. The jumper settings in your
computer are preset at the factory; however, you can alter the
following functions by changing the standard settings:
Enable or disable the built-in VGA display adapter
Enable or disable the password function
Set the computer to use a color or monochrome monitor
Enable or disable the built-in mouse connector.
If you need to change any jumper settings, follow the
instructions in this section.
