Preface
This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite A130/ A135, 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.

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.

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.

1.5 Power Supply |
1.5Power Supply
This specification defines the performance and characteristic of 65W, 75W, and 90W AC adapter power supply. It supplies a constant voltage 19V output source for Satellite P200/ P205 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: blue)
•Blue: indicates AC adaptor 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

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.

1.6 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 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.
