Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite/Satellite Pro/C650D/C655D , referred to as Satellite/Satellite Pro/C650D/C655D 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.

4B1.5 Power Supply

1.5 Power Supply

The power supply unit provides many different voltages for the system board and performs the following functions:

1. Power input monitor

yChecks whether the DC power supply (AC adapter) is connected to the computer.

yChecks whether the battery pack is connected to the computer.

yMonitors the DC power supply input voltage (AC Adapter output voltage).

2.Power supply's internal control

yTurns on and off the battery pack charging power supply.

yIssues a charging current instruction to the PWM control IC of the battery pack charging power supply.

yControls the supply of DC power supply input (AC Adapter output) to the power supply unit.

yControls the supply of power to the system block (load/logic circuit side).

yControls forced shutdown if the power supply malfunctions.

3.Logic circuit control

yInstructs the gate array to enable/disable tuning the power on.

yControls power-on/off operation.

4.Status display

yTurns on the Power LED (in Green).

yBattery indicator (in Green or Amber).

5.External interface

yPerforms communication through the I2C bus (via the internal EC/KBC).

yTransfers the power supply operation mode.

6.Output monitor

yMonitors the voltage output to the system block (load/logic circuit side).

yMonitors the voltage, over voltage, input/output current of the battery pack.

yMonitors the internal temperature of the battery pack.

yMonitors the supply voltage from the AC adapter.

5B1.6 Batteries

1 Hardware Overview

1.6 Batteries

The computer has the following 2 types of battery:

Main Battery Pack

Real Time Clock (RTC) Battery

Table 1-3 lists the specifications of these batteries.

Table 1-3 Battery Specifications

	Battery Type		Material	Output voltage	Capacity
		3 Cell	Lithium Ion	10.8 V	2000 mAh
	Main Battery Pack
		6 Cell	Lithium Ion	10.8 V	4400 mAh
	RTC Battery		Lithium Ion	3.0 V	220 mAh

1.6.1Main 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 so that it can resume it.

1.6.2Battery Charging Control

Battery charging is controlled by MAXIM MAX17435ETG+. When AC adapter and battery pack are attached to the computer, MAX17435ETG+ 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.

1 Hardware Overview

5B1.6 Batteries

State		Charge Time
Off-State Charge	3/6 Cell		About 4 hours max
On-State Charge	3/6 Cell		About 4~10 hours max

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.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.

1.6.3One time 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.

One time RTC battery is replaceable for service, it is located under keyboard.
