Power and Power-Up Modes
The computer’s power resources include the AC adaptor and internal
batteries. This chapter gives details on making the most effective use of
these resources including charging and changing batteries, tips for saving
battery power, and power up modes.
Power conditions
The computer’s operating capability and battery charge status are affected
by the power conditions: whether an AC adaptor is connected, whether a
battery is installed and what the charge level is for the battery.
