Status Charging time
Quick charge 1 4 hours
(power off)
Quick charge 2 4.5 to 12.5 hours

NOTES 1: 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.
2: Using quick charge 1, the system CPU automatically stops the charge
after five hours and 30 minutes regardless of the condition of the battery.
If one of the following occurs, the battery quick charge process stops.
1. The battery becomes fully charged.
2. The AC adapter or battery is removed.
3. The battery or output voltage is abnormal.
❑
Trickle Battery Charge
When the main battery is fully charged and the AC adapter is attached, the micropro-
cessor automatically changes quick charge 1 or 2 to trickle charge.
❑

detected under any of the following conditions:
1. The current in the battery charging circuit drops under the fixed limit.
2. The charging time exceeds the fixed limit.
