3-4 Managing Power
The charging times are as follows:
Charging Time at 25 C (77 F)
Computer is On and
in Video Playback State
CAUTION: After the computer has been fully recharged, do not immediately
disconnect and reconnect the AC adapter to charge it again. Doing so may
damage the battery.
NOTE: The battery level may automatically lessen due to the self-discharge
process (0.21 % per day), even when the battery pack is fully charged (100 %).
This happens no matter if the battery pack is installed in the computer.
Initializing the Battery Pack
You need to initialize a new battery pack before using it for the first time or when
the actual operating time of a battery pack is much less than expected. Initializing
is the process of fully charging, discharging, and then charging. It can take several
hours.
A tool called “Gauge Reset” is provided for the purpose. See “Gauge Reset” in
Chapter 6 for information on using the tool.
