3.Insert a replacement battery pack into the battery bay by following the figures below.

Charging the battery

To charge the battery, place the battery pack inside the battery bay and plug the AC adapter into the computer and an electrical outlet.

Charging modes

The adapter has three charging modes:

Rapid mode

The computer uses rapid charging when power is turned off and a powered AC adapter is connected to it. In rapid mode, a fully depleted battery gets fully charged in two to three hours.

Charge-in-use mode

When the computer is in use with the AC adapter plugged in, the computer also charges the battery pack if installed. This mode will take longer to fully charge a battery than rapid mode. In charge-in-use mode, a fully depleted battery gets fully charged in approximately six to seven hours.

Trickle mode

When the battery is fully charged, the adapter changes to trickle mode to maintain the battery charge level. This prevents the battery from draining while the computer is in use.

Tip! We suggest that you charge the battery pack before retiring for the day, letting it charge overnight before traveling. This ensures a fully charged battery for use the next day.
