VAIO PCV-J100 Upgrading and Maintaining

Replacing the Lithium Battery

After several years, when the lithium battery starts to weaken, the system settings
stored in CMOS RAM, such as the date and time, may be wrong. When this
occurs, you need to replace the lithium battery.
To replace the lithium battery:
1 Write down any changes you have made to the settings in the BIOS Setup
utility. If you have not made any changes to the BIOS settings, proceed to
step 2.
2 Shut down your computer and turn off all peripheral devices, such as your
printer. Unplug your computer.
3 Remove the sideplate as described on page 3.
4 If necessary, remove any cables, add-in cards, or other components to access
the lithium battery.
5 Remove the old battery and install the new battery with the plus (+) side up.
