Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite SATELLITE M30X, referred to as the M30X Series in this
manual.
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.
