Battery Charging Control

Battery charging is controlled by a power supply microprocessor. The 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.
Quick Battery Charge
When the AC adaptor 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.
Status
Quick charge 1
(Power off)
Quick charge 2
(Power on)
NOTE: The time required for quick charge 2 is affected by the amount of power the system
is consuming. Use of the fluorescent lamp and frequent disk access diverts power and
lengthens the charge time.
If any of the following occurs, the battery quick charge process stops.
1. The battery becomes fully charged.
2. The AC adaptor or battery is removed.
3. The battery or output voltage is abnormal.
Detection of full charge
A full charge is detected only when the battery is charging at quick charge. A full charge is
detected under any of the following conditions:
1. The current in the battery charging circuit drops under the predetermined limit.
2. The charging time exceeds the fixed limit.
