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.
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
or Thunderbolt™ 4/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.

Be aware that the charging time when the computer is on is affected
by ambient temperature, the temperature of the computer and how
you are using the computer. If you make heavy use of external
devices for example, the battery might scarcely charge at all during
operation.
