1 Hardware Overview 1.5 Power Supply

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 10-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

• Direct CD 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: green)

• Green = indicates AC adaptor is connected

Battery LED (two colors: orange and green)

• Green solid = The battery is fully charged.

1-16 Satellite P30 Series Maintenance Manual

1.5 Power Supply 1 Hardware Overview

• Orange = The computer is quick-charging the battery / The battery is low.

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 E
read information of the newly installed battery.

10. Battery capacity calculation

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

Satellite P30 Series Maintenance Manual 1-17

1 Hardware Overview 1.6 Batteries

1.6 Batteries

The computer has two types of battery:

 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 battery 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

1-18 Satellite P30 Series Maintenance Manual

1.6 Batteries 1 Hardware Overview

NOTES

1. The time required for normal charge is affected by the amount of power the system
is consuming. Use of the fluorescent lamp and frequent disk access diverts power
and lengthens the charge time.

2. Using quick charge, the power supply microprocessor automatically stops the
charge after eight hours regardless of the condition of the battery. Overcharging
could cause the battery to explode.

If any of the following occurs, the battery quick charge process stops.

1. The battery becomes fully charged.

2. The AC adaptor or battery is removed.

3. The battery or output voltage is abnormal.

4. The battery temperature is abnormal.

5. The battery SMBus communication fails.

6. The battery cell is bad.

 Detection of full charge

A full charge is detected from the battery pack through SMBus when the battery is
charging.

1.6.2 RTC battery

The RTC battery provides power to keep the current date, time and other setup information in
memory while the computer is turned off. The table below lists the charging time and data
preservation period of the RTC battery. The RTC battery is charged by the adaptor or main
battery, while the computer is powered on.

Status Time

Charging Time (power on) About 48 hours

Data preservation period (full charge) 2 month
