Coin-Cell Battery

Dell™ Latitude™ X1 Service Manual

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in your Product Information Guide.

A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.

The battery may need replacing if you have repeatedly reset the time and date information after turning on the computer or if a message appears that is similar to one of the following:

Time-of-day not set - please run SETUP programs

or

Invalid configuration information -{

please run SETUP program

or

Strike the F1 key to continue, {

F2 to run the setup utility

To determine whether you need to replace the battery, reenter the time and date in system setup and exit the program to save the information. Turn off your computer and 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 battery.

You can operate your computer without a battery; however, without a battery, the configuration information is erased if the computer is turned off or unplugged from the electrical outlet. In that case, you must enter system setup and reset the configuration options.

CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
