Power and Power-Up Modes

The computer's power resources include the AC adaptor, battery pack and
any internal batteries. This chapter provides details on making the most
effective use of these resources, and includes information on charging and
changing batteries, tips for saving battery power, and information on the
different power-up modes.

Power conditions

The computer's operating capability and battery charge status are affected
by different power conditions, including whether an AC adaptor is
connected, whether a battery pack is installed and what the charge level is
