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 batteries
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 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
glows amber while the battery is being charged.

The following table shows the approximate time required to charge an

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.
Battery charging notice
The battery might not begin charging immediately under the following
conditions:
The battery is extremely hot or cold (if the battery is extremely hot, it
might not charge at all). To ensure the battery charges to its full
capacity, charge it at room temperature of between 5°C to 35°C (41–
95°F).
The battery is nearly completely discharged. In this instance, leave the
AC adaptor connected for a few minutes and the battery should begin
charging.
