Charging the battery pack

You can charge the battery pack when the AC Adapter is connected to the computer and the battery pack is installed. You need to charge the battery pack if any of the following conditions are true:


  1. Before you charge the battery pack, ensure that its temperature is at least 10°C (50°F).

  2. If the battery pack has not been used for a long time, it will not be fully charged with only a single charging. You will have to completely discharge it; then recharge it three to six times to maximize battery operating time.

  3. The system does not start charging the battery pack until its capacity becomes 94% or lower to extend the battery life.
