Power
The computer’s power resources include the AC power cord 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 in DOS and
Windows.
Power Conditions
The computer’s operating capability and battery charge status are affected by the power
conditions: whether an AC power cord is connected, whether a battery is installed and what
the charge level is for the battery.
