Padlock

Your computer is equipped with a padlock loop such that the cover cannot be removed when a padlock is installed.

vTo complete the installation, go to “Replacing the cover and connecting the cables” on page 24.

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.
