Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite/Satellite Pro/C650D/C655D , referred to as
Satellite/Satellite Pro/C650D/C655D 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, RTC battery or backup 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/Satellite Pro/C650D/C655D Maintenance Manual iii
The manual is divided into the following parts:
Chapter 1 Hardware Overview describes the Satellite/Satellite
Pro/C650D/C655D 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
Keyboard scan/character codes
Key layout
iv Satellite/Satellite Pro/C650D/C655D Maintenance Manual
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

1 Hardware Overview 4B1.5 Power Supply
1.5 Power Supply
The power supply unit provides many different voltages for the system board and performs the
following functions:
1. Power input monitor
y Checks whether the DC power supply (AC adapter) 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 current instruction to the PWM control IC of the battery pack charging
power supply.
y Controls the supply 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 (in Green).
y Battery indicator (in Green or Amber).
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.

5B1.6 Batteries 1 Hardware Overview
1.6 Batteries
The computer has the following 2 types of battery:
Main Battery Pack
Real Time Clock (RTC) Battery
Table 1-3 lists the specifications of these batteries.
Table 1-3 Battery Specifications
Battery Type Material Output voltage Capacity
3 Cell Lithium Ion 10.8 V 2000 mAh
Main Battery Pack
6 Cell Lithium Ion 10.8 V 4400 mAh
RTC Battery Lithium Ion 3.0 V 220 mAh
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 so that it can
resume it.
1.6.2
Battery Charging Control
Battery charging is controlled by MAXIM MAX17435ETG+. When AC adapter and
battery pack are attached to the computer, MAX17435ETG+ 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.

1 Hardware Overview 5B1.6 Batteries
State Charge Time
Off-State Charge 3/6 Cell About 4 hours max
On-State Charge 3/6 Cell About 4~10 hours max
NOTE: The time required for normal charge depends on the power consumption by the
system. Using the fluorescent lamp and frequently accessing the disk consume much power
and lengthen the charge time.
Any of the following cases stops battery charge:
1. The battery becomes fully charged.
2. The AC adapter or battery pack is removed.
3. The battery or AC adapter voltage 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 charging circuit drops below the predetermined value.
2. The charging time exceeds the fixed limit.
1.6.3 One time RTC Battery
The RTC battery provides power to keep the current date, time and other system
information in memory while the computer is turned off.
One time RTC battery is replaceable for service, it is located under keyboard.
