Password protection

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

vTo complete the installation, go to “Closing the cover and connecting the cables” on page 31.

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.

Refer to “Lithium battery notice” on page x for information about replacing and disposing of the battery.

To change the battery:

1.Open the computer cover. See “Opening the cover” on page 19.

2.Pivot the drive bay assembly upward to gain access to the system board.
