Battery Packs

Running the Notebook on Battery Power

The notebook switches between AC power and battery power according to the availability of an external AC power source, always preferring AC power. If the notebook contains a charged battery pack and is running on external AC power, the notebook will switch to battery power only if the AC adapter is disconnected from the notebook.

Keeping a battery pack in the notebook enables the battery pack to charge whenever the notebook is connected to external power and also protects your work in case of a power outage.

On the other hand, a battery pack in the notebook slowly discharges even when the notebook is powered off. Whether to leave a battery pack in the notebook or in storage depends on how you work.
