Preface
This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite A100/A105 / TECRA A7, referred to as Satellite A100/A105 / TECRA A7 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, RTC battery or backup 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. User input Text that you are instructed to type in is shown in the boldface type below: DISKCOPY A: B: The display Text generated by the XXXXX that appears on its display is presented in the type face below:

1 Hardware Overview
1.7 Power Supply
The power supply unit provides many different voltages for the system board and performs the following functions: 1. Power input monitor Checks whether the DC power supply (AC adapter) is connected to the computer. Checks whether the battery pack is connected to the computer. Monitors the DC power supply input voltage (AC Adapter output voltage). 2. Power supply's internal control Turns on and off the battery pack charging power supply. Issues a charging current instruction to the PWM control IC of the battery pack charging power supply. Controls the supply of DC power supply input (AC Adapter output) to the power supply unit. Controls the supply of power to the system block (load/logic circuit side). Controls forced shutdown if the power supply malfunctions. 3. Logic circuit control Instructs the gate array to enable/disable tuning the power on. Controls power-on/off operation. 4. Status display Turns on the Power LED (in Blue or Green or AMBER). Battery indicator (in Blue or Green or AMBER or AMBER Flash). 5. External interface Performs communication through the I2C bus (via the internal EC/KBC). Transfers the power supply operation mode. 6. Output monitor Monitors the voltage output to the system block (load/logic circuit side). Monitors the voltage, over voltage, input/output current of the battery pack. Monitors the internal temperature of the battery pack. Monitors the supply voltage from the AC adapter.

NOTE: The time required for normal charge depends on the power consumption by the system. Using the fluorescent lamp and frequently accessing the disk consume much power and lengthen the charge time.
Any of the following cases stops battery charge: 1. 2. 3. The battery becomes fully charged. The AC adapter or battery pack is removed. 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. 2. 1.1.3 The current in the battery charging circuit drops below the predetermined value. The charging time exceeds the fixed limit.
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.

2.2 Basic Flowchart
The basic flowchart in Figure 2-1 serves as a guide for identifying a possibly faulty FRU. Before going through the diagnostic flowchart steps, verify the following: Ask the user if a password has been registered and, if so, ask him or her to enter the password. If the user has forgotten the system password, use a jump wire to make a short circuit on M/B C88 , then turn the computer power on. When booted, the computer overrides password protection and automatically erases the current password. Make sure the Windows® XP Home Edition has been installed on the HDD. Any other operating system can cause the computer to malfunction. Make sure any piece of optional equipment has been installed.
