Charging batteries
NOTE: Battery charge time may vary depending on the
applications, power management settings, and features used.
The main battery and the optional secondary battery need to
be charged before you can use them to power the computer.

Charging the main and secondary batteries

To charge the main battery, plug the computer into a live wall
outlet. It takes several hours to charge the battery with the
computer off. It takes much longer to charge the battery while
the computer is on. Once the main battery is charged, the
secondary battery, if inserted into the Modular Bay, will
charge.
TECHNICAL NOTE: The battery does not charge while the
computer is consuming full power.
To charge the secondary battery, fit it in the Modular Bay and
connect the computer to an AC power source.
TECHNICAL NOTE: When batteries are being charged, the main
battery is charged first. After the main battery is fully charged, the
secondary battery in the Modular Bay is charged.
When the batteries discharge, the secondary battery in the
Modular Bay will discharge first, then the main battery.
A battery may not start charging immediately if:
❖
The battery is extremely hot or cold.
