Replacement procedure
Note: During the installation, ensure that you align the memory module to the slot and press down on both
ends until the latches are fully engaged with a click.
Coin-cell battery
Prerequisite
Before you start, read Generic Safety and Compliance Notices, and print the following instructions.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel connector assignments (configurations). A coin-cell battery keeps this information active
when you turn off the computer.
The coin-cell battery normally requires no charging or maintenance throughout its life; however, no coin-cell
battery lasts forever. If the coin-cell battery fails, the date and time information is lost. An error message is
displayed when you turn on the computer.
To dispose of the coin-cell battery, refer to the "Lithium coin-cell battery notice" in the Safety and Warranty
Guide.
For access, remove these parts in order, if any:
• "Computer cover" on page 28
