Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer TECRA A9,S5,P5,Satellite Pro S200.
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.

Conventions
This manual uses the following formats to describe, identify, and highlight terms and
operating procedures.
Acronyms
On the first appearance and whenever necessary for clarification acronyms are enclosed in
parentheses following their definition. For example:
Read Only Memory (ROM)
Keys
Keys are used in the text to describe many operations. The key top symbol as it appears on
the keyboard is printed in boldface type.
Key operation
Some operations require you to simultaneously use two or more keys. We identify such
operations by the key top symbols separated by a plus (+) sign. For example, Ctrl + Pause
(Break) means you must hold down Ctrl and at the same time press Pause (Break). If
three keys are used, hold down the first two and at the same time press the third.

1.9.1 Main Battery
The removable main battery pack is the computer’s main power source when the AC adaptor
is not attached. The main battery maintains the state of the computer when the computer
enters in sleep mode.
TECRA A9(S5/P5/S200) Maintenance Manual (960-633)[CONFIDENTIAL] 1-27
1 Hardware Overview 1.9 Batteries
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 1-8 lists the charging time required for charges.
Table 1-8 Time required for charges
Battery type Power on (hours) Power off (hours)
Battery(4,000 mAh) About 4.5 to 9.5 About 2.5
Battery(5,100 mAh) About 5.5 to 12.0 About 3.0
Battery(5,400 mAh) About 5.5 to 12.0 About 3.0
High capacity battery(7,200 mAh) About 8.0 to 19.5 About 3.5
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.

causing the computer to malfunction. The FRUs covered are:
1. Power Supply 6. Display 11. Wireless LAN
2. System Board 7. Optical Drive 12. Sound components
3. USB Floppy Disk Drive 8. Modem 13. SD Card Slot
4. Hard Disk Drive 9. LAN 14. Fingerprint sensor
5. Keyboard/Dual point 10. Bluetooth .
The Diagnostics Disk operations are described in Chapter 3. Detailed Replacement
Procedures are given in Chapter 4, Replacement Procedures.
The following tools are necessary for implementing the troubleshooting procedures:
The following tools are necessary for implementing the Diagnostics procedures:
For tools required for executing the Test Program, refer to the Chapter3. For tools required
for disassembling/assembling, refer to the Chapter 4.
1. A set of tools for debugging port test (test cable, test board, RS-232C cross cable,
display, D port FD)
2. A PC with a serial port (for displaying debug port test result)
3. DOS system FD
4. An external CRT display(for Display trouble shooting)

TECRA A9(S5/P5/S200) Maintenance Manual (960-633)[CONFIDENTIAL] 2-1
2 Troubleshooting Procedures 2.2 Troubleshooting Flowchart
2.2 Troubleshooting Flowchart
Use the flowchart in Figure 2-1 as a guide for determining which FRU malfunctions. Before
going through the flowchart steps, check the following:
Ask the user if a password is registered and, if it is, ask him or her to enter the
password.
Make sure that Toshiba Windows is installed on the hard disk. Non-Toshiba
operating systems can cause the computer malfunction.

system board.
• If the DC IN jack is not firmly connected, go to Procedure 5.
• If it is connected, go to Check 4.
Check 4 Use a multimeter to make sure the AC adaptor output voltage is close to 15 V. If
the output is several percent lower than 15 V, go to Check 5. If the output is close
to 15 V, go to Check 6.
Check 5 Connect a new AC adaptor or AC power cord.
• If the DC IN icon does not light, go to Procedure 5.
• If the battery icon does not light, go to Check 6.

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 DOS or Windows 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.
