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 between 5 and 35
degrees Celsius. Otherwise, the electrolyte solution might leak, battery
pack performance might deteriorate and the battery life might be
shortened.
Charging the batteries
When the power in the battery pack becomes low, the DC IN/Battery
indicator will flash 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 will enable Hibernation Mode so that you do
not lose any data, and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.

Procedures

To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack
and plug the other end into a working outlet - the DC IN/Battery indicator
will glow amber while the battery is being charged.

Please 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.
