Battery Pack
You can increase the portability of the computer with Battery Packs (PA3154U). If
you’re away from an AC power source, you can replace a low battery with a fully
charged one. See Chapter 6, Power and Power-Up Modes.
High Capacity 2nd Battery Pack
You can install an optional High Capacity 2nd Battery Pack in the computer. A High
Capacity 2nd Battery Pack (PA3155U) is seated in a base that fits beneath the
computer. It provides about twice the power and operating time as the standard
Battery Pack. Refer to the High Capacity 2nd Battery Pack Information Sheet.
Universal AC Adaptor
If you frequently transport the computer between different sites such as your home
and office, purchasing an AC adaptor for each location will reduce the weight and
bulk of your carrying load: PA3153U.
