Using the fluorescent lamp and frequently accessing the disk consume much power and lengthen the charge time. Any of the following cases stops battery charge: 1. The battery becomes fully charged. 2. The AC adapter or battery pack is removed. 3. The battery or AC adapter voltage is abnormal. ‰ Detection of full charge A full charge is detected only when the battery is being charged by quick or normal charge. A full charge is detected when either of the following conditions is met: 1. The current in the battery charging circuit drops below the predetermined value. 2. The charging time exceeds the fixed limit. 1.8.3 RTC Battery The RTC battery provides power to keep the current date, time and other system information in memory while the computer is turned off.

On-State Charge
3/6/9 Cell
About
4~10 hours max
NOTE:
The time required for normal charge depends on the power consumption by the
system.
Using the fluorescent lamp and frequently accessing the disk consume much
power and lengthen the charge time.
Any of the following cases stops battery charge:
1.
The battery becomes fully charged.
2.
The AC adapter or battery pack is removed.
3.
The battery or AC adapter voltage is abnormal.
Detection of full charge
A full charge is detected only when the battery is being charged by quick or normal
charge.
A full charge is detected when either of the following conditions is met:
1.
The current in the battery charging circuit drops below the predetermined
value.
2.
The charging time exceeds the fixed limit.
