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.

Tecra A3/S2 Maintenance Manual ii

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.

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.

1.5 Power Supply 1 Hardware Overview

1.5 Power Supply

The power supply supplies seven different voltages to the system board and performs the
following functions:

1. A/D conversion

The EC uses 8-bit sampling for A/D conversion to determine the following values:

? AC adaptor current
? Battery and temperature

2. AC adaptor and battery check

The EC checks the following by A/D converted values:

? Battery installed

The EC checks the following by GPIO values:

? AC adaptor connected

3. Abnormal check

The EC determines whether the condition is abnormal, and if so, stores an error code into
the error register.

4. Input port management

The EC monitors the following input signal status:

? System power ON/OFF status

5. Beep and LED control

Beep is caused by the low battery status.
The EC controls the following two kinds of LED

DC IN LED (one color: Blue or Green(by sku))
? Green = indicates AC adaptor is connected

Battery LED (two colors: Green & Orange ? Blue & Orange)

? Blue or Green solid = The battery is fully charged.
? Orange = The computer is quick-charging the battery / The battery is low.

Tecra A3/S2 Series Maintenance Manual 1-19

1 Hardware Overview 1.5 Power Supply

6. Power ON/OFF sequence

When power is turned on or off, the EC starts the power on or off sequence.

? SQ0-4 = power ON sequence
? SQ5-B = power OFF sequence

7. Battery charging control

The EC controls the following.

? The quick charging ON/OFF
? The detection of full charge

8. Detection of the low battery

The EC detects the low battery point by the gas gauge.

? LB10M= The system will be driven by the battery for 12 more minutes.
? LB0 = The battery won't be able to drive the system after 3 minutes.
? LB1 = The battery can drive the system only during the suspend process.
? LB2 = The battery cannot drive the system.

9. New battery installation

When a new battery is installed, the EC communicates with the E2PROM in the battery to
read information of the newly installed battery.

10. Battery capacity calculation

The EC reads battery remaining and percentage capacity from the battery through SMBus.

1.6 Batteries 1 Hardware Overview

1.6 Batteries

The computer has two types of batter y:

? Main battery pack (18650 size)
? RTC battery

The removable main battery pack is the computer’s main power source when the AC adaptor is
not attached.

The battery specifications are listed in the table below.

Battery name Material Output voltage Capacity

Main battery Lithium-Ion 14.8 V 6450mAH/

4300mAH

RTC bat tery Lithium 3 V 14 mAH/15 mAH

1.6.1 Main Battery

Battery charging is controlled by a power supply microprocessor that is mounted on the system
board. The power supply microprocessor controls whether the charge is on or off and detects a
full charge when the AC adaptor and battery are attached to the computer. The system charges
the battery using quick charge or trickle charge.

? Quick Battery Charge

When the AC adaptor is attached, there are two types of quick charge: quick charge when
the system is powered off and normal charge when the system is powered on.

The times required for charges are listed in the table below.

Status Charging time

Normal charge (power on) 12 hours or longer
Quick charge (power off) About 4 hours
