Padlock loop

Padlock loop

Your computer is equipped with a padlock loop that locks the cover to your computer when a padlock is installed. Using a padlock at least or at 5 mm or 3/16-inch can secure your computer cover to help prevent unauthorized people from gaining access to the inside of your computer.

Password protection

To deter unauthorized use of your computer, you can use the Setup Utility program to set a password. When you turn on your computer you are prompted to type the password to unlock the keyboard for normal use.

What to do next

vTo work with another option, go to the appropriate section.

vTo complete the installation, go to “Replacing the cover and connecting the cables” on page 37.

Changing the battery

Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer.

The battery normally requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer.
