1.9.3 Battery Charging Control

Battery charging is controlled by a power supply microprocessor mounted on the system board. The power supply microprocessor controls whether the charge is on or off and detects a full charge when the AC adaptor and battery are attached to the computer. The system charges the battery using quick charge or trickle charge.

Battery Charge

When the AC adaptor is attached, battery charge starts.

The times required for quick charges are listed in Table 1-8.
