Satellite A500/ ProA500 Series Maintenance

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 m

essages 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.

1.4 Power Supply

The power supply unit provides constant voltage (19V) for the system board and performs the following functions:

1. Power input monitor

 Checks whether the AC adapter (DC power supply) 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 Green).  Battery indicator (in Green or Amber).  DC-IN indicator (in Green)

5. External interface

 Performs communication through the I2C bus (via the internal EC/KBC).  Transfers the power supply operation mode.

1 Hardware Overview Error! Style not defined. Error! Style not defined.

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.

1.5 Batteries

The computer has the following two types of batteries:

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

1.5.1 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.

1.5.2 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 1-3 Quick/Normal Charging Time

State Charge Time

Off-State Charge 3/6/12 Cell About 4 hours max

On-State Charge 3/6/12 Cell About 12 hours max

Satellite L500 Maintenance Manual 1-13

1 Hardware Overview Error! Style not defined. Error! Style not defined.

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 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.

1.5.3 RTC Battery

The RTC battery provides power to keep the current date, tim memory while the computer is turned off.

3.1 The Diagnostic Test

This chapter explains how to use the Test & Diagnostic program to test the functions of the (Base on Liveropool 10M/10MG T&D version 1.0) hardware modules. The Test & Diagnostic Program is stored on the T&D diskettes. The program consists of a series of tests that run automatically when the Diagnostics Program items are selected and executed.

NOTES: To start the diagnostics, follow these steps

1. Check all cables for loose connections.

2. Exit this program when you are at Main Menu.

The TEST & DIAGNOSTIC PROGRAM contains the following functional tests:

 CONFIG CHECK TEST  Audio sound TEST  FAN ON/OFF TEST  MAIN BATTERY CHARGE TEST  FDD TEST  Memory check  KEYBOARD TEST  MOUSE(PAD) TEST  LCD PIXELS MODE TEST  MAGNETIC SWITCH TEST  LAN TEST  RTC TEST  BUTTON TEST

HDD Test

 RDMI Test  WDMI Test  HDCP KEY CHECK

You will need the following equipment to perform some of the Diagnostic test programs.

 The diagnostics USB disk  A formatted working diskette for the floppy disk drive test (Floppy Disk Drive Test)  A LAN loopback

3.2 Executing the Diagnostic Test

DOS is required to run the DIAGNOSTICS PROGRAM. To start the DIAGNOSTIC PROGRAM, follow these steps:

Insert the diagnostics USB disk drive and turn on the computer. (The diagnostics diskette contains the Free-DOS boot files.) And then follow the instructions for T&D program installed in USB driver)

The T&D Program can run single test by you press corresponsive English letter of test item, and it also asks you if you like to copy test log file to USB disk as reference at the end of test(s).

The test list is as the following:

A. CONFIG CHECK TEST B. Audio sound TEST C. FAN ON/OFF TEST D. MAIN BATTERY TEST E. FDD TEST F. Memory check G. KEYBOARD TEST H. MOUSE (PAD) TEST I. LCD PIXELS MODE TEST J. MAGNETIC TEST K. LAN TEST L. RTC TEST M. BUTTON TEST N. 1st HDD Test O. RDMI Test P. WDMI Test Q. HDCP KEY CHECK

3. 7 FDD Test

NOTE: Before running the FDD test, prepare a formatted work diskette (1.44 MB). Need to insert FDD when power on machine. Otherwise the Floppy can not be detected.

The Floppy Disk Test includes three subtests of the:

1. Sequential seek/verify function (Range: Track 0 ~ 79)

2. Funnel code seek/verify function (Range: Track 0 ~ 79)

3. Write/Read/Compare pattern function (Range: Track 75 ~ 79)

NOTE: The write-protected device of this formatted diskette should be “Disable”.

The subtests run automatically.

NOTE: Press “Esc” key can skip the current subtest.

The screen should display as below, indicating whether the subtests pass or fail when finished.
