Figure 4-25. System Battery Removal
To remove the system battery, follow these steps:
1. Before turning off the system, if possible enter the System Setup
program and make a printed copy of the System Setup screens
(see Appendix A).
2. Remove any expansion cards that block access to the battery.
3. Remove the battery (see Figure 4-25) by prying it out of its socket
with your fingers or with a blunt, nonconducting object, such as a
plastic screwdriver.
To replace the system battery, orient the new battery with the “+” facing up.
Insert the battery into its socket and snap it into place. After system boot, com-
pare the system configuration information with the copy of the system
configuration settings you made in step 1. Restore any system configuration informa-
tion that was lost while the battery was replaced.
NOTE: As a result of the power loss while replacing the battery, you may lose
portions of the current system firmware. If, after replacing the system battery,
you receive the message Warning: Firmware is out-of-date,
please update..., reflash the system firmware from the Dell Server Assis-
tant CD (if available) or download it from the Dell website.
WARNING
There is a danger of the new battery exploding if 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.
