As the fingerprint for each finger is different and unique, you should
ensure that only the registered or enrolled fingerprint or fingerprints
are used for identification.
The fingerprint sensor compares and analyzes the unique
characteristics in a fingerprint. However, there might be instances
where certain users are unable to register their fingerprints due to
insufficient unique characteristics in their fingerprints.
The recognition success rate might differ from user to user.
Battery
This section explains battery types, use, recharging methods and handling.
Battery pack
When the AC adaptor is not connected, the main power source of the
computer is a lithium ion battery pack, also referred to in this manual as the
main battery.
Real-Time Clock (RTC) function
The Real-Time Clock (RTC) function is supported. The main battery
provides power for the internal real-time clock and calendar function and
also maintains the system configuration while the computer is turned off. If
the RTC lasting time completely runs out, the system will lose this
information and the real-time clock and calendar will stop working.
You can change the Real-Time Clock settings in the dynabook Setup
Utility. Refer to
Real-Time Clock for further information.
Care and use of the battery pack
This section provides the important safety precautions in order to handle
your battery pack properly.
Refer to the enclosed
Instruction Manual for Safety and Comfort for
detailed precautions and handling instructions.
Charge the battery pack only in an ambient temperature from 5 through 35
degrees Celsius. Otherwise, the electrolyte solution might leak, battery
pack performance might deteriorate, and the battery life might be
shortened.
Charging the battery
When the power in the battery pack becomes low, the DC IN/Battery
indicator flashes amber to indicate that only a few minutes of battery power
remain. If you continue to use the computer while the
DC IN/Battery
indicator flashes, the computer enters Hibernation Mode so that you do not
lose any data, and automatically turns itself off.
