Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer PORTEGE A600
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 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 battery capacity.
8. Controls the transmission of the status signal of the main battery.
The power supply output rating is specified in Table 1-8.

The computer has three types of batteries as follows:
Main battery pack
RTC battery
The battery specifications are listed in Table 1-7.

1.10.1 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.

1 Hardware Overview 1.10 Batteries
1.10.2 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(2,900 mAh) About 5.0 to 7.5 About 5.0
Battery(5,800 mAh) About 6.5 to 15.0 About 5.0
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 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 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 the F1 key as the message instructs, the SETUP screen appears to set
the system configuration. If error message (b) appears often when the power is
turned on, replace the RTC battery. If any other error message is displayed,
perform Check 2.
(a) *** Bad HDD type ***
Check system. Then press [F1] key ......
(b) *** Bad RTC battery ***
Check system. Then press [F1] key ......

Check system. Then press [F1] key ......
Check 2 If the following error message is displayed on the screen, press any key as the
message instructs.
The following error message appears when data stored in RAM under the resume
function is lost because the battery has become discharged or the system board is
damaged. Go to Procedure 3.
WARNING: RESUME FAILURE.
PRESS ANY KEY TO CONTINUE.
If any other error message displays, perform Check 3.

The test procedures are follows:
1. Connect the debug port test cable to the connector CN3490 of the system board. For
disassembling to connect the test cable, refer to Chapter 4.
2. Connect the debug port test cable and RS-232C cross-cable to the test board.
3. Connect the RS-232C Cross-cable to the PC that displays the test results.
4. Boot the computer in MS-DOS mode.
5. Execute GETDPORT.COM in the text menu in CPU REAL mode. (Insert the FD for
starting D port into FDD and input “FD starting drive:>dport”.)

To check if the HDD/SSD 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 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.
