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
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.
Never replace the battery by an incorrect type, which could possibly
result in an explosion.
Never expose a battery to excessive heat, extremely low temperatures
or extremely low air pressure at high altitude during use, storage or
transportation as that may result in an explosion or the leakage of
flammable liquid or gas.
Do not mechanically crush or cut the battery as that may result in an
explosion. Always dispose of used batteries according to the
instructions.
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.
You must recharge the battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack/
USB Type-C™ port and plug the other end into a working outlet. The
DC
IN/Battery
indicator glows amber while the battery is being charged.
