Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite A210, 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

iv
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
This specification defines the performance and characteristics of the 75W, 90W, and 120W
AC adapter power supply. It supplies a constant voltage 19V output source for the Minnesota
10A/10AG (Satellite A210/ A215, Satellite Pro A210, EQUIUM A210, SATEGO A210
Series)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 adapter and battery check
• The EC checks the following by A/D converted values:
– Battery installed
• The EC checks the following by GPIO values:
– AC adapter 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: blue)
• Blue: indicates AC adapter is connected
– Battery LED (two colors: orange and blue)
• Blue 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

1.5 Power Supply 1 Hardware Overview
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 E
PROM 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.

1.6 Batteries 1 Hardware Overview
1.6.1 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 adapter and battery are attached to the computer. The
system charges the battery using quick charge or trickle charge.
Quick Battery Charge
When the AC adapter is attached, there are two types of quick charges: 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 (po we r off) About 4 hours
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 adapter 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.

1.6.2 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 adapter 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
