1.4 Batteries
The computer has the following two types of batteries:
Main Battery Pack
Real Time Clock (RTC) Battery
1.4.1 Main Battery
The main battery pack serves as the computer's main power source when the AC adapter is not
attached. The main battery maintains the state of the computer when the AC adapter is detached.
1.4.2 Battery Charging Control
Battery charging is controlled by EC KB926. When the AC adapter and battery pack are attached
to the computer, the EC KB926 controls the charge on/off state and detects a full charge.
Battery Charge
When the AC adapter is attached, the battery is charged by off-state charge when the system
is powered off or by on-state charge when it is powered on.
Table 1-2 Quick/Normal Charging Time
State Charge Time
3 Cell About 4 hours
Off-State Charge
6 Cell About 6 hours
On-State Charge 3/6 Cell About 12 hours
NB200 Maintenance Manual 1-12
Error! Style not defined. Error! Style not defined. 1 Hardware Overview
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.
1.4.3 RTC Battery
The RTC battery provides power to keep the current date, time and other system
memory while the computer is turned off.
