microprocessor controls whether the charge is on or off, and detects a full charge when the AC
adapter and battery are attached to the computer. The system charges the battery using a quick
charge or trickle charge.

When the AC adapter is attached, there are two types of quick charge: quick charge 1
when the system is powered off, and quick charge 2 when the system is powered on.
