Preface

This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer TECRA M2V.

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
