When the charge provided by your battery pack is supplied for only a short period of
time, even after fully charging according to the instructions, it may be time to replace
your battery pack. The battery pack is a consumable item and therefore will require
replacement (CF-VZSU04).
CAUTION
Do not touch the terminals on the battery pack. The battery pack may no longer
function properly if the contacts are dirty or damaged.
The battery pack is not charged when the computer is first purchased. Be sure to
charge it before using it for the first time. When the AC adapter is connected to the
computer, charging begins automatically.
