1.5 Batteries

The computer has one type of battery as follows:

Main battery pack

The battery specifications are listed in Table 1-3.

Table 1-3 Battery specifications

Battery name Material Output voltage Capacity

Main battery (1S2P) Li-ion 3.7V 6600 mAh

1 Hardware Overview

1.5.2 Battery Charging Contro l

Battery charging is controlled by an embedded controller (EC). The EC 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.

Battery Charge

When the AC adaptor is attached, there are two types of charge: When the system is powered

off and when the system is powered on. Table 1-4 lists the charging time required for

charges.

Table 1-4 Time required for charges

Battery type Power on (hours) Power off (hours)

1st battery pack 8 hours max 6 hours max

NOTE: The time required when the system is powered on 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.

If any of the following occurs, the battery 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.

Detection of full charge

A full charge is detected only when the battery is charging at charge. A full charge is

detected under any of the following conditions:

1. The current in the battery charging circuit drops under the predetermined limit.

2. The charging time exceeds the fixed limit.
