Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer QOSMIO F30 series.

NOTE: Each model of QOSMIO F30 series has a different configuration. For each

model’s configuration, refer to the parts list dedicated to it.

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. Be sure to use the PH

Point size “0” and “1” screwdrivers complying with the ISO/DIS 8764-1:1996. 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.

2.1 Troubleshooting

Chapter 2 describes how to determine which Field Replaceable Unit (FRU) in the computer is causing the computer to malfunction. (The “FRU” means the replaceable unit in the field.) The FRUs covered are:

1. Power supply 7. Display 13. Sound

2. System Board 8. Optical Disk Drive 14. TV Tuner

3. USB FDD 9. Modem 15. Bridge Media slot

4. 2.5” HDD 10. LAN 16. Fingerprint Sensor

5. Keyboard 11. Wireless LAN

6. Touch pad 12. Bluetooth

The Test Program operations are described in Chapter 3. Detailed replacement procedures are described in Chapter 4.

NOTE: Before replacing the system board, it is necessary to execute the subtest 03 DMI

Information save of the 3.4 Setting of the hardware configuration in Chapter 3.

After replacing the system board, it is necessary to execute the subtest 04 DMI

Information recovery and subtest 08 System configuration display of the 3.4 Setting of the hardware configuration in Chapter 3. Also update with the latest EC/KBC as described in Appendix H “EC/KBC Rewrite Procedures”.

After replacing the LCD, update with the latest EC/KBC as described in Appendix

H “EC/KBC Rewrite Procedures” to set the SVP parameter.

The implement for the Diagnostics procedures is referred to Chapter 3. Also, following implements are necessary:

1. Phillips screwdrivers (For replacement procedures)

2. Implements for debugging port check

•

Procedure 1: Power Status Check Procedure 2: Error Code Check Procedure 3: Connection Check Procedure 4: Charging Check Procedure 5: Replacement Check

Procedure 1 Power Status Check

The following icons indicate the power supply status:

 Battery icon  DC IN icon

The power supply controller displays the power supply status with the Battery icon and the DC IN icon as listed in the tables below.

Table 2-1 Battery icon

Battery icon Power supply status

Lights orange Battery is cha rge d and the external DC is input. It has no

relation with ON/OFF of the system power.

Lights green Battery is fully charged and the external DC is input. It has

no relation with ON/OFF of the system power.

Blinks orange (even intervals)

Blinks orange once (at being switched on)

Doesn’t light Any condition other than those above.

The battery level is low while the system power is ON.

The system is driven by only a battery and the battery level is low.

Lights green DC power is being supplied from the AC adapter. Blinks orange Power supply malfunction Doesn’t light Any condition other than those above.

*1 When the power supply controller detects a malfunction, the DC IN icon blinks

orange. It shows an error code.

When the icon is blinking, perform the following procedure.

1. Remove the battery pack and the AC adapter.

2. Re-attach the battery pack and the AC adapter.

If the icon is still blinking after the operation above, check the followings:

Check 1 If the DC IN icon blinks orange, go to Procedure 2. Check 2 If the DC IN icon does not light, go to Procedure 3. Check 3 If the battery icon does not light orange or blue, go to Procedure 4.

NOTE: Use a supplied AC adapter G71C00043310, G71C00058210, G71C0002R810 (2-

2-18 [CONFIDENTIAL] QOSMIO F30 Maintenance Manual (960-555)

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 ......

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

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

(e) *** Bad time function ***

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

(f) *** Bad check sum (CMOS) ***

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

(g) *** Bad check sum (ROM) ***

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.

Check 3 The IRT checks the system board. When the IRT detects an error, the system stops

or an error message appears. If one of the following error messages (1) through (17), (23) or (24) is displayed,

go to Procedure 4. If error message (18) is displayed, go to the Keyboard Troubleshooting Procedures. If error message (19), (20) or (21) is displayed, go to the 2.5” HDD

Procedure 2 Debugging Port Check

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

Figure 2-2 A set of tool for debug port test

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

6. When the D port status is FFFFh (normal status), go to Procedure 4.

7. When the D port status falls into any status in Table 2-4, execute Check 1.
