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

iv [CONFIDENTIAL] Satellite L670/L675/ Pro L670/L675 Series Maintenance Manual
The manual is divided into the following parts:
Chapter 1 Hardware Overview describes the Satellite Series 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
Screw torque list
Reliability
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

Satellite L670/L675/ProL670/L675 Series Maintenance Manual [CONFIDENTIAL] v
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
Text that you are instructed to type in is shown in the boldface type below:

Satellite L670/Pro L670 Maintenance Manual[CONFIDENTIAL]
LAN (BTO)
The computer has built-in support for 10M/100M Ethernet LAN (10/100 megabits per
second, 10/100BASE-T). It employs a Realtek RTL8105E for 10M/100Mbit LAN (for
discrete platform, Realtek RTL8111E for 10M/100M/1000M is employed). It is pre-
installed as a standard device in some markets.
Wireless LAN (BTO)
Some computers in this series are equipped with a Wireless LAN (WLAN) card. This
WLAN module may come with the following types (depending on the model):
