Dell OptiPlex 760 Service Manual
Replacing the Battery
|WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.|
|CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.|
A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.
The battery may need replacing if an incorrect time or date is displayed during the boot routine along with a message such as:
Time-of-day not set - please run SETUP program
Invalid configuration information -
please run SETUP program
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 (see Entering 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 this case, you must enter system setup (see Entering System Setup) and reset the configuration options.
|WARNING: 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.|
To remove the battery:
|CAUTION: If you pry the battery out of its socket with a blunt object, be careful not to touch the system board with the object. Ensure that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise, you may damage the system board by prying off the socket or by breaking circuit traces on the system board.|
|CAUTION: To avoid damage to the battery connector, you must firmly support the connector while removing the battery.|
