Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite T110, Satellite Pro T110, and PORTEGE T110 Series.

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 m

anual 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.

Satellite T110 / Satellite Pro T110 / PORTEGE T110 Maintenance Manual (960-Q08)

The manual is divided into the following parts:

Chapter 1 Hardware Overview describes the Satellite T110, Satellite Pro T110,

PORTEGE T110 system unit and each FRU.

Chapter 2 Troubleshooting Procedures explains how to diagnose and resolve

FRU problems.

Chapter 3 Test and Diagnostics describes how to perform test and diagnostic

operations for maintenance service.

Chapter 4 Replacement Procedures describes the removal and replacement of the

FRUs.

Appendices The appendices describe the following:

 Handling the LCD Module  Board layout  Pin assignments  Keyboard scan/character codes  Key layout  Wiring diagrams

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 sym

bol 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.
