Preface

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

1.5 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 whe ther 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 I nstru cts 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 (White or Amber color). y Battery indicator (White or Amber color). y DC-IN indicator (White color).

5. External interface

1.6 Batteries 1 Hardware Overview

1.6 Batteries

The computer has the following two types of batteries:

 Main Battery Pack  Real Time Clock (RTC) Battery

1.6.1 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.

1.6.2 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.

Table 1-4 Quick/Normal Charging Time

State Charge Time

Off-State Charge 6/12 Cell About 4 hours

On-State Charge 6/12 Cell About 12 hours

Satellite M600/M640/M645/M647 Maintenance Manual 1-17

Downloaded from LpManual.com Manuals

1 Hardware Overview 1.6 Batteries

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 stop 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 dro ps below the predetermined value.

2. The charging time exceeds the fixed limit.

1.6.3 RTC Battery

The RTC battery provides power to maintain the current date, time and other system information in memory while the computer is turned off.

2.2 Troubleshooting Flowchart

If you know the location of the malfunction, turn directly to the appropriate section of this chapter. If the problem is unspecified, use the flowchart in Figure 2-1 as a guide for determining which troubleshooting procedures to execute. Before performing any troubleshooting procedures, verify the following:

z Ask the user if a password is registered, if it is, ask him or her to enter the password. z Verify with the customer that Toshiba Windows7 is installed on the hard disk. Operating

systems that were not preinstalled by Toshiba can cause the computer to malfunction.

z Make sure all optional equipment is removed from the computer. z Make sure the floppy disk drive, if installed, is empty. If no ODD module is installed,

you should use an external ODD to run the diagnostics tests

Any of the connectors may be disconnected. Perform Check 1. Check 1 Disconnect the AC power cord from wall outlet. Check the power cable for

breaks. If the power cord is damaged, connect a new AC power cord. If there is no damage, go to Check 2.

Check 2 Make sure the AC adaptor cord and AC power cord are firmly plugged into the

DC-IN socket, AC adaptor inlet and wall outlet. If these cables are connected correctly, go to Check 3.

Check 3 Make sure that the DC-IN input port socket is firmly secured to the system board

of the computer.

• If the DC-IN input socket is loose, go to Procedure 5.

• If it is not loose, go to Check 4.

Check 4 Use a multi-meter to make sure that the AC adaptor output voltage is close to 19

V. If the output is several percent lower than 19 V, go to Check 5. If the output is close to 19 V, go to Check 6.

Check 5 Connect a new AC adaptor or AC power cord.

• If the DC-IN LED does not light, go to Procedure 4.

• If the battery LED does not light, go to Check 6.

Check 6 Make sure the battery pack is installed in the computer correctly. If the battery is

properly installed and the battery LED still does not light, go to Procedure 4.

This section describes how to determine if the computer’s display is functioning properly. The process is outlined in Figure 2-3. Start with Procedure 1 and continue with the other procedures as instructed.

Procedure 1: External display check Procedure 2: Diagnostic check Procedure 3: Connector and replacement check

Procedure 1 External display check

Connect an external display to the computer’s external monitor port, and then boot the computer. The computer automatically detects the external display.

If the external display works correctly, the internal LCD may be damaged. Go to Procedure 3. If the external monitor appears to have the same problem as the internal monitor, the system

board may be damaged. Go to Procedure 2.

Procedure 2 Diagnostic check

The Display Test program is stored on the computer’s Diagnostics disk. This program checks the display controller on the system board. Insert the Diagnostics disk in the computer’s floppy disk drive, turn on the computer and run the test. Refer to Chapter 3, Tests and Diagnostics for details.

If an error is detected, go to Procedure 3. If an error is not detected, the display is functioning properly.
