Preface
This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer STREAMLINE-M 10A SERIES MAINTENANCE MANUAL, referred to as the STREAMLINE-M 10A SERIES MAINTENANCE MANUAL 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 STREAMLINE-M 10A SERIES
MAINTENANCE MANUAL 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
Text that you are instructed to type in is shown in the boldface type below:

1 Hardware Overview
1.3 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 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 White). y Battery indicator (in White or Amber). y DC-IN indicator (in White)
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.

1.4 Batteries
The computer has the following two types of batteries:
Main Battery Pack Real Time Clock (RTC) Battery
1.4.1 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.
1.4.2 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.

State Charge Time
Off-State Charge 6 Cell About 4 hours max
On-State Charge 6 Cell About 12 hours max
Satellite/Satellite PRO T230D Maintenance Manual 1-12
1 Hardware Overview
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 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.
1.4.3 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.
