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.
Satellite M640/ProM640 Series Maintenance Manual iii

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

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 M640/ProM640 Series Maintenance Manual iv
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.

play BDs, DVDs and CDs. At maximum the drives can playback BD at 6x speed, DVD at 8x
speed, read CD-ROM at 24x speed.
The BD-RE and BD-Combo drives let you record data to writable CD/DVD discs. The drives
can write CD-R at 24x speed, CD-RW at 16x speed, DVD-R at 8x speed, DVD-RW at 6x speed,
DVD+R at 8x speed, DVD+R (DL) at 4x speed, DVD-R (DL) at 4x speed, DVD+RW at 4x
speed and DVD-RAM at 5x speed.
In addition to being able to write to recordable CD/DVD discs, th e BD-RE drive can write to
BD-R as 6x speed, BD-R (DL) at 4x speed, BD-RE at 2x speed and BD-RE (DL) at 2x speed.

1.5 Power Supply 1 Hardware Overview
Satellite M600/M640/M645/M647 Maintenance Manual 1-15
1.5 Power Supply
The power supply unit provides constant voltage (19V) for the system board and performs the
following functions:
1. Power input monitor
y Checks whether the AC adapter (DC power supply) is connected to the computer.
y Checks whether the battery pack is connected to the computer.
y Monitors the DC power supply input voltage (AC Adapter output voltage).
2. Power supply's internal control
y Turns on and off the battery pack charging power supply.
y Issues a charging curren t instruction to the PWM control IC of the battery pack charg ing
power supply.
y Controls the suppl y of DC power supply input (AC Adapter output) to the power supply
unit.
y Controls the supply of power to the system block (load/logic circuit side).
y Controls forced shutdown if the power supply malfunctions.
3. Logic circuit control
y Instructs the gate array to enable/disable tuning the power on.
y Controls power-on/off operation.
4. Status display
y Turns on the Power LED (White or Amber color).
y Battery indicator (White or Amber color).
y DC-IN indicator (White color).
5. External interface
y Performs communication through the I2C bus (via the internal EC/KBC).
y Transfers the power supply operation mode.

6. Output monitor
y Monitors the voltage output to the system block (load/logic circuit side).
y Monitors the voltage, over-voltage, input/output current of the battery pack.
y Monitors the internal temperature of the battery pack.
y Monitors the supply voltage from the AC adapter.
1.6 Batteries 1 Hardware Overview
Satellite M600/M640/M645/M647 Maintenance Manual 1-17
1.6 Batteries
The computer has the following two types of batteries:
Main Battery Pack
Real Time Clock (RTC) Battery
1.6.1 Main Battery
The main battery pack serves as the computer's main power source when the AC adapter is not
attached. The main battery maintains the state of the computer when the AC adapter is detached.
1.6.2 Battery Charging Control
Battery charging is controlled by EC KB926. When the AC adapter and battery pack are attached
to the computer, the EC KB926 controls the charge on/off state and detects a full charge.
Battery Charge
When the AC adapter is attached, the battery is charged by off-state charge when the system
is powered off or by on-state charge when it is powered on.
Table 1-4 Quick/Normal Charging Time
State Charge Time
Off-State Charge 6/12 Cell About 4 hours
On-State Charge 6/12 Cell About 12 hours
1 Hardware Overview 1.6 Batteries
Satellite M600/M640/M645/M647 Maintenance Manual 1-18
NOTE: The time required for normal charge depends on the power consumption by the
system. Using a fluorescent lamp and frequently accessing the disk consumes more power
and lengthens the charge time.
Any of the following can stop battery charge:
1. The battery becomes fully charged.
2. The AC adapter or battery pack is removed.
3. The battery or AC adapter voltag e is abnormal.
Detection of full charge
A full charge is detected only when the battery is being charged by quick or normal charge.
A full charge is detected when either of the following conditions is met:
1. The current in the battery char ging circuit drops below the predetermined value.
2. The charging time exceeds the fix ed limit.
1.6.3 RTC Battery
The RTC battery provides power to maintain the current date, time and other system information
in memory while the computer is turned off.
