Preface

This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer PORTÉGÉ R500.

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.

User input

1.10 Batteries

The computer has three types of batteries as follows:

 Main battery pack

 RTC battery

The battery specifications are listed in Table 1-7.

Table 1-7 Battery specifications

Battery name Material Output

Lithium-Ion 10.8 V

Capacity

5,800 mAh

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.

1-22 [CONFIDENTIAL] PORTEGE R500 Maintenance Manual (960-634)

1.10 Batteries 1 Hardware Overview

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.

in memory while the computer is turned off. Table 1-9 lists the charging time and data
preservation period of the RTC battery.

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.

 Make sure all optional equipment is removed from the computer.

Procedure 3 Connection Check

The power supply wiring diagram is shown below:

Any of the connectors may be disconnected. Perform Check 1.
Check 1 Disconnect the AC power cord from the wall outlet. Check the power cable for

breaks. If the power cord is damaged, connect a new AC power cord. If there is
no damage, go to Check 2.

Check 2 Make sure the AC adaptor cord and AC power cord are firmly plugged into the

DC-IN jack socket and AC adaptor inlet/wall outlet, respectively. If these cables
are connected correctly, go to Check 3.

Check 3 Make sure the DC IN jack is firmly connected to the connector CN8800 on the

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.

PORTEGE R500 Maintenance Manual (960-634) [CONFIDENTIAL] 2-15

2 Troubleshooting Procedures 2.4 System Board Troubleshooting

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.

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

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

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

Procedure 2 Debugging Port Check (Boot Mode)

Check the D port status by a serial port test. The tool for serial port test is shown below.

Figure 2-2 Debug port (Boot mode) error status

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 compute1r in 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”.)
The D port status is displayed in the following form;
