Software Functional Overview

3.5.19 AC Adapters and Power Source Objects

The Power Source objects describe the power source used to run the system.

Object

Description

_PSR

Returns present power source device

 

 

_PCL

List of pointers to powered devices.

 

 

_PSR

Returns the current power source devices. Used for the AC adapter and is located under the AC adapter object in name space. Used to determine if system is running off the AC adapter. Arguments: None

Results code: 0x00000000 = Off-line;0x00000001 = On-line

_PCL

This object evaluates to a list of pointers, each pointing to a device or a bus powered by the power source device. Pointing a bus means that all devices under the bus is powered by it power source device.

3.6Battery Management

The A360 supports both Li-Ion and Ni-MH Battery Pack. There is only one battery pack activating at one time. The special designed Bridge Battery module can backup the system under Suspend To RAM mode for a short period of time.

3.6.1Battery Sub-system

The charger will stop charge the battery when the following condition is detected.

The temperature of the system is too high

The remaining capacity is 95% and more.

• Battery Life

2.5 to 3 Hours.

Battery reading methodology is through PMU07 SMBus.

Note that the battery life is dependent on different configuration running. E.g. with CD-ROM battery life is shorter, document keyin only battery life is longer, PMU disable battery life is short, PMU enable battery life is longer.

3.6.2Battery Low Warning

When the battery capacity remains 8%, the PMU07 will generate a battery warning SMI. The system will do the following action.

The Power LED Indicator will continually blinking with 1 Hz.

The system issues a warning beep (3 beeps at once).

3.6.3Battery Low

When the battery capacity remains 3%, the system will generate a battery low SMI. The system will do the following action.

The system will enter Suspend To Disk mode even the power management is
