NOTE:

The time required for normal charge depends on the power consumption by the

system. Using a fluorescent lamp and frequently accessing the disk consumes more power and
lengthens the charge time.

Any of the following can 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.

1.5.3

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.
