Battery
WARNING: Before working inside your computer, read the safety
information that shipped with your computer and follow the steps in
"Before You Begin" on page 9. For additional safety best practices
information, see the Regulatory Compliance Homepage at dell.com/

disconnect it from the electrical outlet for a few hours; then reconnect the computer, turn
it on, and enter system setup. If the date and time are not correct in system setup, replace
the coin-cell battery.
You can operate your computer without a coin-cell battery; however, without a coin-cell
battery, the configuration information is erased if the computer is turned off or
disconnected from the electrical outlet. In this case, you must enter system setup and
reset the configuration options.
WARNING: The battery may explode if installed incorrectly.
Replace the battery only with the same or equivalent type.
Discard used batteries according to the manufacturer’s instructions.
CAUTION: Removing the coin-cell battery resets the BIOS settings
to default. It is recommended that you note the BIOS settings before
removing the coin-cell battery.
