Satellite/Satellite Pro/L650/L655 Maintenance Manual

Preface

This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Satellite/Satellite Pro/L650/L655, referred to as Satellite/Satellite Pro/L650/L655 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:

1.7.1Main 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.

1.7.2Battery Charging Control

Battery charging is controlled by WINBOND NPCE781L. When AC adapter and battery pack are attached to the computer, the NPCE781L 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.

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.

22

Satellite/Satellite Pro/L650/L655 Maintenance Manual

1.7 Batteries

1 Hardware Overview

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.

1.7.3RTC 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

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 B500 location, then turn the computer power on. When booted, the computer overrides password protection and automatically erases the current password.

Make sure the Windows® 7 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.

2.4 System Board

To check if the system board is defective or malfunctioning, follow the troubleshooting procedures below as instructed.

Procedure 1 Message Check Procedure 2 Test Program Check Procedure 3 Replacement Check

Procedure 1 Message Check

When the power is turned on, the system performs the self-diagnostic Power On Self Test (POST) embedded in the BIOS ROM. The POST tests and initializes each IC on the system board.

If an error message appears on the display, perform Check 1.

If there is no error message, go to Procedure 2.

If FREE-DOS or Windows 7 Home Edition is loaded normally, go to Procedure 3.

Check 1 If the following error message is displayed on the screen, press the F1 key as prompted. These errors occur when the system configuration preserved in the RTC memory (generally called CMOS memory) does not match the actual configuration or when the data is lost.

If you press the F1 key as prompted by the message, the TSETUP screen appears to set the system configuration. If the error message appears frequently when the power is turned on, replace the RTC battery. If any other error message is displayed, perform Check 2.

*** Bad RTC battery ***
