1.7 Power Supply

The power supply supplies many different voltages to the system board and performs the following functions:

1. Judges that the DC power supply (AC adapter) is connected to the computer.

2. Detects DC output and circuit malfunctions.

3. Controls the battery icon, and DC IN icon.

4. Turns the battery charging system on and off and detects a fully charged battery.

5. Turns the power supply on and off.

6. Provides more accurate detection of a low battery.

7. Calculates the remaining ba tt ery capacity.

8. Controls the transmission of the status signal of the main battery.

The power supply output rating is specified in Table 1-8

1 Hardware Overview

1.8.2 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 1-6 Time required for charges

Battery type Power on (hours) Power off (hours)

Battery (8Cell 47Wh ) about 3.5 to 8.0 About 3.0

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.

Troubleshooting Procedures

2.4.1 Procedure 1 Message Check

When the power is turned on, the system performs the Initial Reliability Test (IRT) installed in the BIOS ROM. The IRT tests each IC on the system board and initializes it.

 If an error message is shown on the display, perform Check 1.  If there is no error message, go to Procedure 2.  If MS-DOS or Windows OS is properly loaded, go to Procedure 4.

Check 1 If one of the following error messages is displayed on the screen, press the F1 key

as the message instructs. These err o rs occur when the system configura tion preserved in the RTC memory (CMOS type memory) is not the same as the actual configuration or when the data is lost.

If you press the F1 key as the message instructs, the SETUP screen appears to set the system configuration. If error me ssa ge (b) appears often when the power is turned on, replace the RTC battery. If any other error message is dis pla yed, perform Check 2.
