Battery Power
NOTE
After disconnecting the battery pack, if you connect it to a computer on which the battery's Economy Mode (ECO)
settings differ, the battery will either recharge or discharge until the next time the computer is turned on, giving priority
to the battery pack setting on that computer.
Replacing the Battery Pack
The battery pack is a consumable item so the replacement will be necessary. If the battery operation time becomes noticeably
short and not recovered even after recalibrating the battery, replace with a new battery.
CAUTION
The battery pack is not charged when you first purchase it. Be sure to charge it before using for the first time. Charging
starts automatically when the AC adaptor is connected to the computer.
Use only the specified battery pack with your computer.
