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.
1.1.3 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.

2 Troubleshooting 2.2 Basic Flowchart
2.2 Basic Flowchart
The basic flowchart in Figure 2-1 serves as a guide for identifying a possibly faulty FRU.
Before going through the diagnostic flowchart steps, verify the following:
Ask the user if a password has been registered and, if so, ask him or her to enter the
password. If the user has forgotten the system password, use a jump wire to make a
short circuit on M/B C88 , then turn the computer power on. When booted, the
computer overrides password protection and automatically erases the current
password.
Make sure the Windows® XP Home Edition has been installed on the HDD. Any
other operating system can cause the computer to malfunction.
Make sure any piece of optional equipment has been installed.
