1.7 Batteries

The computer has two types of batteries:

 Main battery pack

 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 Table 1-4.

Battery name Material Output voltage Capacity

Main battery Lithium-Ion 14.8 V 6,450 mAh

RTC battery Lithium 3.0 V 14 mAh

Table 1-4 Battery specifications

Satellite A30 Series Maintenance Manual 1-13

1 Hardware Overview 1.7 Batteries

1.7.1 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 time required for quick charges is listed in Table 1-5.

Status Charging time

Normal charge (power on) 8 hours or longer

Quick charge (power off) About 4 hours

Table 1-5 Time required for quick charges

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.

1-14 Satellite A30 Series Maintenance Manual

1.7 Batteries 1 Hardware Overview

 Detection of full charge

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

1.7.2 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. Table 1-6 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.
