Preface

This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite Pro S300, TECRA A10/S10/P10

The procedures described in this manual are intended to help service technicians isolate
faulty Field Replaceable Units (FRUs) and replace them in the field.

SAFETY PRECAUTIONS

Four types of messages are used in this manual to bring important information to your
attention. Each of these messages will be italicized and identified as shown below.

DANGER: “Danger” indicates the existence of a hazard that could result in death or

serious bodily injury, if the safety instruction is not observed.

WARNING: “Warning” indicates the existence of a hazard that could result in bodily

injury, if the safety instruction is not observed.

CAUTION: “Caution” indicates the existence of a hazard that could result in property

damage, if the safety instruction is not observed.

NOTE: “Note” contains general information that relates to your safe maintenance

service.

Improper repair of the computer may result in safety hazards. Toshiba requires service
technicians and authorized dealers or service providers to ensure the following safety
precautions are adhered to strictly.

 Be sure to fasten screws securely with the right screwdriver. If a screw is not fully

fastened, it could come loose, creating a danger of a short circuit, which could cause
overheating, smoke or fire.

 If you replace the battery pack or RTC battery, be sure to use only the same model

battery or an equivalent battery recommended by Toshiba. Installation of the wrong
battery can cause the battery to explode.

1.9 Batteries 1 Hardware Overview

1.9.2 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 1-10 Time required for charges

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

Battery(4,000 mAh) About 3.0 to 9.5 About 2.5

Battery(5,100 mAh) About 4.0to 12.0 About 3.0

Extended Capacity battery (7,050 mAh) About 5.0 to 19.5 About 3.5

High capacity battery(7,200 mAh) About 6.0 to 21.0 About 4.0

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.

To check if the USB FDD is malfunctioning or not, follow the troubleshooting procedures
below as instructed.

Procedure 1: FDD Head Cleaning Check

Procedure 2: Diagnostic Test Program Execution Check

Procedure 3: Connector Check and Replacement Check

Procedure 1 FDD Head Cleaning Check

Procedure 2 Diagnostic Test Program Execution Check

Insert the Diagnostics Disk in the USB FDD, turn on the computer and run the test. Refer to

Chapter 3, Tests and Diagnostics, for more information about the diagnostics test procedures.

Make sure the floppy disk is formatted correctly and that the write protect tab is disabled.
Floppy disk drive test error codes and their status names are listed in Table 2-7. If any other
errors occur while executing the FDD diagnostics test, go to Check 1.

Table 2-5 FDD error code and status

Check 1 If the following message is displayed, disable the write protect tab on the floppy

disk by sliding the write protect tab to “write enable”. If any other message
appears, perform Check 2.

Write protected

Check 2 Make sure the floppy disk is formatted correctly. If it is, go to Procedure 3.

2.5 USB FDD Troubleshooting 2 Troubleshooting Procedures

Procedure 3 Connector Check an d Replacement Check

USB FDD is connected to USB port on system board. The connection of the cable and board
may be defective. Otherwise, they may be faulty. Disassemble the computer following the

steps described in Chapter 4, Replacement Procedures and perform the following checks.

USB FDD can be connected to the following 4 ports.
(System board x 1 ports and USB/MDC board x 3 port)

Check 1 Make sure USB FDD is firmly connected to USB port. If the connection is loose,

connect firmly and repeat Procedure 2. If the problem still occurs, go to Check 2.

NOTE: When checking the connection, be sure to check it with care for the followings.

1. Cable can not be disconnected from the connector.

2. Cable is connected straight to the connector.

3. Cable is connected all the way seated in the connector.

4. Cable or connector can not be broken.

Check 2 Connect USB FDD to other USB port and check if it works properly. If it does not

work properly, perform Check 3

Check 3 USB FDD may be faulty. Replace it with a new one. If the problem still occurs,

perform Check 4

Check 4 System board and USB / MDC board may be faulty. Replace it with a new one

2.6 2.5” HDD Troubleshooting 2 Troubleshooting Procedures

2.6 2.5” HDD Troubleshooting

To check if the 2.5” HDD is malfunctioning or not, follow the troubleshooting procedures
below as instructed.

Procedure 1: Partition Check

Procedure 2: Message Check

Procedure 3: Format Check

Procedure 4: Diagnostic Test Program Execution Check

Procedure 5: Connector Check and Replacement Check

CAUTION: The contents of the hard disk will be erased when the 2.5”HDD

troubleshooting procedures are executed. Transfer the contents of the hard
disk to floppy disks or other storage drive(s). For the backup, refer to the
User’s Manual.

Procedure 1 Partition Check

Insert the Toshiba MS-DOS system disk and start the computer. Perform the following
checks:

Check 1 Input C: and press Enter. If you cannot change to drive C, go to Check 2. If you

can change to drive C, go to Procedure 2.

Check 2 Input FDISK and press Enter. Choose Display Partition Information from the

FDISK menu. If drive C is listed in the Display Partition Information, go to Check

3. If drive C is not listed, return to the FDISK menu and choose the option to
create a DOS partition or a logical DOS drive on drive C. If the problem still
occurs, go to Procedure 2.

Check 3 If drive C is listed as active in the FDISK menu, go to Check 4. If drive C is not

listed as active, return to the FDISK menu and choose the option to set the active
partition for drive C. Then go to Procedure 2.

Check 4 Remove the system disk from the FDD and reboot the computer. If the problem

still occurs, go to Procedure 2. Otherwise, the 2.5” HDD is operating normally.

2 Troubleshooting Procedures 2.6 2.5” HDD Troubleshooting

Procedure 2 Message Check

When the power is turned on, the system performs the Initial Reliability Test (IRT) installed
in the BIOS ROM. When the test detects an error, an error message is displayed on the screen.

Make sure no floppy disk is in the FDD. Turn on the computer and check the message on the
screen. When an OS starts from the 2.5” HDD, go to Procedure 3. Otherwise, start with
Check 1 below and perform the other checks as instructed.

Check 1 If any of the following messages appear, go to Procedure 3. If the following

messages do not appear, perform Check 2.

HDC ERROR

or

HDD #X ERROR (After 5 seconds this message will disappear.)

Check 2 If either of the following messages appears, go to Check 3. If the following

messages do not appear, perform Check 4.

Insert system disk in drive

Press any key when ready .....

or

Non-System disk or disk error
Replace and press any key when ready

Check 3 Using the SYS command of the DOS, transfer the system to the 2.5” HDD. If the

system is not transferred, go to Procedure 3. Refer to the DOS Manual for detailed
operation.

If the following message appears on the display, the system program has been
transferred to the HDD.

System Transferred

If an error message appears on the display, perform Check 4.

Check 4 2.5” HDD(s) and the connector(s) of system board may be defective (Refer to the

steps described in Chapter 4, Replacement Procedures for disassembling.). Insert
