To replace the battery:
1. Record all the screens in system setup so that you can restore the correct settings in step8.
2. Follow the procedures in "Before You Begin."
3. Locate the battery socket.
4. Remove the battery by carefully prying it out of its socket with your fingers or with a blunt, nonconducting object such as a plastic screwdriver.
5. Insert the new battery into the socket with the side labeled "+" facing up, and snap the battery into place.
6. Replace the computer cover.
7. Connect your computer and devices to electrical outlets, and turn them on.
8. Enter system setup and restore the settings you recorded in step1.
9. Properly dispose of the old battery. See the Product Information Guide for battery disposal information.

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.
