Preface

This maintenance manual describes how to perform hardware service maintenance for the

Toshiba Personal Computer Satellite / Satellite Pro L510 / L515 / L517, referred to as

Satellite / Satellite Pro L510 / L515 / L517 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.

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 so that it

can resume it.

Battery Charging Control

Battery charging is controlled by WINBOND NPCE781LA0DX. When the AC

adapter and battery pack are attached to the computer, the NPCE781LA0DX 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.

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.

1.1.3

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.

3. Keyboard

6. LAN

See Chapter 4 for the procedures to replace FRUs and Chapter 3 for the procedures to use test

programs

The following tools are required to perform the diagnostic procedures:

1. Diagnostics (maintenance test program) disk

2. Phillips screwdrivers (2 mm, 2.5 mm)

3. Cleaning disk kit (for ODD drive cleaning)

4. Bootable CD

5. Multi-meter

6. External monitor

7. Headphone

8. Microphone

9. A-BEX TEST DVD

10. Music CD

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® Vista 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.
