Coin-cell battery
Attention: Do not open your computer or attempt any repair before reading and understanding the
Appendix A “Important safety information” on page 97.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-connector 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 and time information is lost.
Refer to the “Lithium coin cell battery notice” in the Safety and Warranty Guide for information about
replacing and disposing of the battery.
To replace the coin-cell battery, do the following:
1. Prepare your computer. See “Preparing your computer” on page 24.
2. Locate the battery.
3. Remove any parts that might impede your access to the battery. Depending on your computer model,
you might need to remove the PCI card for easier access to the battery. See “PCIe card” on page 30 or
“Full-length PCIe card” on page 33.
4. Remove the old battery.

5. Install a new battery.

6. Reinstall the PCI card if you have removed it. See “PCIe card” on page 30 or “Full-length PCIe card” on
page 33.
7. Reinstall the computer cover and connect the cables. See “Completing the parts replacement” on page
89.
Note: When the computer is turned on for the first time after replacing the battery, an error message
might be displayed. This is normal after replacing the battery.
8. Turn on the computer and all attached devices.
9. Reset the system date and time in the UEFI BIOS menu.
