Satellite L450 / ProL450 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 messages are used in this m

anual 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

 Battery indicator (in green or amber).  DC-IN indicator (in green color)

5. External interface

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