Power Switching Between Battery and External 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. To prolong battery life, remove and store the battery pack if the notebook will be unused for 2 weeks or more. For more information, see the "Storing a Battery Pack" section later in this chapter. Charging a Battery Pack The battery pack charges whenever the notebook is connected to external power through an AC adapter. The battery pack charges whether the notebook is turned off or turned on but charges most quickly when the notebook is turned off. When the notebook is turned on, the battery pack may not charge, the charge time may be longer, or the charge time may vary with system activity. Hardware and Software Guide 3-17
