Battery Charging Control
Battery charging is controlled by a power supply microprocessor mounted on the power
supply. The microprocessor turns charging on or off and detects a full charge when the AC
adapter and main battery pack are attached to the computer. The system charges the main
battery pack using quick or trickle charge.
❏
Quick Battery Charge
When the AC adapter is attached, there are two types of charge: quick charge when the
system is powered off and trickle charge when powered on. Table 1-10 gives quick charging
time requirements.
