Satellite X200 Series Maintenance Manual

Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite X200/ X205, referred to as the M100 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 M100 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

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

1.5 Power Supply 1 Hardware Overview

1.6 Power Supply

This specification defines the performance and characteristic of 180W AC adapter power supply. It supplies a constant voltage 19V output source for Satellite X200/ X205 Series Personal Computer.

 A/D conversion

• The EC uses 10-bit sampling for A/D conversion to determine the following

values:

– Battery and temperature

 AC adaptor and battery check

• The EC checks the following by A/D converted values: – Battery installed

• The EC checks the following by GPIO values: – AC adaptor connected

 Abnormal check

• The EC determines whether the condition is abnormal, and if so, stores an error

code into the error register.

 Input port management

• The EC monitors the following input signal status: – System power ON/OFF status – Direct CD power ON/OFF status

 Beep and LED control

• Beep is caused by the low battery status.

• The EC controls the following two kinds of LED

– DC IN LED (one color: red)

• Red: indicates AC adaptor is connected – Battery LED (two colors: orange and red)

• Red solid: The battery is fully charged.

• Orange: The computer is quick-charging the battery / The battery is low.

 Power ON/OFF sequence

• When power is turned on or off, the EC starts the power on or off sequence. – SQ0-4 = power ON sequence – SQ5-B = power OFF sequence

 Battery charging control

• The EC controls the following. – The quick charging ON/OFF – The detection of full charge

 Detection of the low battery

• The EC detects the low battery point by the gas gauge. – LB10M: The system will be driven by the battery for 12 more minutes. – LB0: The battery won't be able to drive the system after 3 minutes. – LB1: The battery can drive the system only during the suspend process. – LB2: The battery cannot drive the system.

 New battery installation

• When a new battery is installed, the EC communicates with the E2PROM in the

battery to read information of the newly installed battery.

 Battery capacity calculation

• The EC reads battery remaining and percentage capacity from the battery

through SMBus.

1 Hardware Overview 1.6 Batteries

1.7.1 Main Battery

Battery charging is controlled by a power supply microprocessor that is mounted on the system board. The power supply microprocessor controls whether the charge is on or off and detects a full charge when the AC adaptor and battery are attached to the computer. The system charges the battery using quick charge or trickle charge.

 Quick battery charge

When the AC adaptor is attached, there are two types of quick charge: quick charge when the system is powered off and normal charge when the system is powered on.

The times required for charges are listed in the table below.

Status Charging time

Normal charge (power on) 12 hours or longer Quick charge (power off) About 4 hours or longer

NOTES

1. The time required for normal charge is affected by the amount of power the system is consuming. Use of the fluorescent lamp and frequent disk access diverts power and lengthens the charge time.

2. Using quick charge, the power supply microprocessor automatically stops the charge after eight hours regardless of the condition of the battery. Overcharging could cause the battery to explode.

If any of the following occurs, the battery quick charge process stops.

1. The battery becomes fully charged.

2. The AC adaptor or battery is removed.

3. The battery or output voltage is abnormal.

4. The battery temperature is abnormal.

5. The battery SMBus communication fails.

6. The battery cell is bad.

 Detection of full charge

A full charge is detected from the battery pack through SMBus when the battery is charging.

1.7.2 RTC battery

The RTC battery provides power to keep the current date, time and other setup information in memory while the computer is turned off. The table below lists the charging time and data preservation period of the RTC battery. The RTC battery is charged by the adaptor or main battery, while the computer is powered on.

Status Time

Charging Time (power on) About 24 hours Data preservation period (full charge) 1 month
