Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Portege M200, referred to as Portege M200 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. Be sure to use the PH

Point size “0” and “1” screwdrivers complying with the ISO/DIS 8764-1:1996. 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.

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.

1 Hardware Overview 1.5 Power Supply

1.5 Power Supply

The power supply supplies 26 different voltages to the system board.

The power supply microcontroller has the following functions.

1. Judges that the DC power supply (AC adapter) is connected to the computer.

2. Detects DC output and circuit malfunctions.

3. Controls the battery icon, and DC IN icon.

4. Turns the battery charging system on and off and detects a fully charged battery.

5. Turns the power supply on and off.

6. Provides more accurate detection of a low battery.

7. Calculates the remaining battery capacity.

8. Controls the transmission of the status signal of the main battery.

G71C0003D210

GDM710000003 Lithium ion 2.4 V 17 mAh

Lithium ion 10.8 V 4,400 mAh

1.6.1 Main Battery

The main battery is the primary power supply for the computer when the AC adapter is not connected. In resume (instant recovery) mode, the main battery maintains the current status of the computer.

1.6.2 Battery Charging Control

Battery charging is controlled by a power supply microprocessor. The power supply microprocessor controls power supply and detects a full charge when the AC adapter and battery are connected to the computer. The system charges the battery using quick charge or trickle charge.
