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.

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 L550/ProL550 Series Maintenance Manual

 

 

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:

1.4 Power Supply

The power supply unit provides constant voltage (19V) for the system board and performs the following functions:

1. Power input monitor

Checks whether the AC adapter (DC power supply) is connected to the computer.

Checks whether the battery pack is connected to the computer.

Monitors the DC power supply input voltage (AC Adapter output voltage).

2. Power supply's internal control

Turns on and off the battery pack charging power supply.

Issues a charging current instruction to the PWM control IC of the battery pack charging

power supply.

Controls the supply of DC power supply input (AC Adapter output) to the power supply

unit.

Controls the supply of power to the system block (load/logic circuit side).

Controls forced shutdown if the power supply malfunctions.

3. Logic circuit control

Instructs the gate array to enable/disable tuning the power on.

Controls power-on/off operation.

4. Status display

Turns on the Power LED (in Green).

Battery indicator (in Green or Amber).

DC-IN indicator (in Green)

5. External interface

Performs communication through the I2C bus (via the internal EC/KBC).

Transfers the power supply operation mode.

6. Output monitor

Monitors the voltage output to the system block (load/logic circuit side).

Monitors the voltage, over-voltage, input/output current of the battery pack.

Monitors the internal temperature of the battery pack.

Monitors the supply voltage from the AC adapter.

1.5 Batteries

The computer has the following two types of batteries:

Main Battery Pack

Real Time Clock (RTC) Battery

1.5.1 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.

1.5.2 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.
