Battery Charging Control
Battery charging is controlled by a power supply microprocessor that is mounted on the
power supply. The microprocessor controls whether the charge is on or off and detects a full
charge when the AC power cord and battery are attached to the computer. The system
charges the battery using quick charge or trickle charge.
❑
Quick Battery Charge
When the AC power cord is attached, there are two types of charge: quick charge
when the system is powered off and trickle charge when the system is powered on.
