Battery Charging Control
Battery charging is controlled by a 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 main battery are attached to the computer.
The system charges the battery using quick charge when the system is powered off, or trickle
charge when the system is powered on. The trickle charge state maintains the full charge of
the battery. Table 1-11 lists the time required for charging the main battery.

2.

When the main battery is fully charged and the AC power cord is attached, the power supply
microprocessor automatically changes quick charge to trickle charge.
