1 Hardware Overview 1.13 Batteries

1.13.2 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 1-12 lists the charging time required for charges.

Table 1-12 Time required for charges

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

High capacity battery (8,800 mAh) About 9.0 to 21.5 About 4.5

Battery (4,700 mAh) About 5.5 to 13.0 About 3.0

2nd battery (3,600 mAh) About 4.0 to 9.5 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.

 Detection of full charge

A full charge is detected only when the battery is charging at charge. A full charge is detected under any of the following conditions:

1. The current in the battery charging circuit drops under the predetermined limit.

2. The charging time exceeds the fixed limit.

2.4 System Board Troubleshooting 2 Troubleshooting Procedures

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 Toshiba MS-DOS or Windows XP is properly loaded, go to Procedure 3.

Check 1 If one of the following error messages appears on the screen, press F1 as the

message instructs. These errors occur when the system configuration 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 F1 as the message instructs, returns all system settings to their default

values. Then the system reboots.

If error message (b) appears often when the power is turned on, replace the RTC

battery. If any other error message displays, perform Check 2.

(a) *** Bad HDD type ***

Check system. Then press [F1] key ......

(b) *** Bad RTC battery ***

Check system. Then press [F1] key ......

(d) *** Bad memory size ***
