Using additional batteries

source, you may purchase a battery module for use in the computer,
or carry additional charged battery packs with you. You can then

Charging the main battery
The battery needs to be charged before you can use it to power the
computer.
To charge the main battery while it is in your computer, plug the
computer into a live electrical outlet. The battery charges whether
the computer is on or off.
TECHNICAL NOTE: The recharging of the battery cannot occur when
your computer is using all of the power provided by the AC adaptor to
run applications, features, and devices. Your computer's Power Options
utility can be used to select a power level setting that reduces the power
required for system operation and will allow the battery to recharge.
The battery may not start charging immediately under the following
conditions:
❖
The battery is extremely hot or cold.
To ensure that the battery charges to its full capacity, wait until
it reaches room temperature (50 to 80 degrees Fahrenheit, 10 to
26 degrees Celsius).
❖
The battery is almost completely discharged.
Leave the power connected and the battery should begin
charging after a few minutes.
