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.

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.

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.

1.5 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.
