1.9.2 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.
Battery Charge
When the AC adaptor is attached, there are two types of charge: When the system is powered
off and when the system is powered on. Table 1-10 lists the charging time required for
charges.
Table 1-9 Time required for charges
Battery type Power on (hours) Power off (hours)
Battery(48Wh, 6 cell) about 3.0 to 10.5 About 2.5
Battery(55Wh, 6 cell) About 4.0to 12.0 About 2.5
NOTE: The time required when the system is powered on 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 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.
