Key Lock
The key lock allows you to disable the keyboard and lock the top
cover of the main unit for security. This provides a safeguard against
someone accessing confidential information or altering your computer’s
internal hardware. The key lock also lets you run an application pro-
gram, such as a screen demonstration, while disabling the keyboard so
no one can alter the display. With the keyboard locked, the computer
does not respond to anything you enter.
You can lock the system whether the power is on or off. To lock it,
insert the key with the notch pointing up and turn it clockwise as shown
in Figure 2-1. You need to press it in slightly when you turn it. To unlock
it, insert the key with the notch pointing to the right and turn the key
counterclockwise. You can remove the key in either position.
Figure 2-1. Locking the key lock
Your Equity III comes with two keys; it is a good idea to store them in
different locations in case you misplace one. Store both keys where they
are safe.
Be sure the computer is unlocked before you try to use the keyboard.
Otherwise, it does not respond to anything you enter.
