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 excess heat, extremely low temperatures or
extremely low air pressure at high altitude during use, storage or
transportation that may result in an explosion or the leakage of
flammable liquid or gas.
Do not mechanically crush or cut the battery 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 turn itself off.
You must recharge the battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to the 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.
Note that charging time will vary depending on the ambient
temperature, the computer's internal temperature, and how the
computer is being used. For example, whether the display is set to
shut off automatically when idle, whether you make heavy use of
external devices powered by the computer, or if the computer's
internal storage drive is being accessed frequently by an application.
