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.

Replacement procedure

1.  Remove the computer cover. See “Computer cover” on page 41.

2.  Remove the front bezel. See “Front bezel” on page 42.

3.  Remove the optical drive. See “Optical drive” on page 45.

4.  Remove the hard disk drive. See “Hard disk drive” on page 47.

5.  Remove the coin-cell battery. 

6.  Install the coin-cell battery. 

7.  Reinstall all the removed parts. Then, reconnect the power cord and all disconnected cables to the 

computer.

8.  Reset the system date and time in the UEFI BIOS menu.
