microsoft acpi compliant control method battery driver.

This must be performed immediately after the platform detects the physical state change. When the state of _PSR changes, the platform must generate an interrupt and a Notify(0x80) command on the device in the ACPI namespace. The _PSR method must only report online (AC power) when the system is connected to main power. This method returns the status of the power source and conveys whether the power source is currently online (AC power) or offline (on battery power). This object must also implement the Power Source (_PSR) method. (Additional power source objects may be present on server systems that have multiple power supplies.) Client systems must not provide multiple power source device objects. This object must represent the composite status of power inputs for the system. Note For systems that have multiple power sources, all physical power sources must be multiplexed through a single power device object in ACPI. This object must report itself with a Hardware ID (_HID) of 'ACPI0003'. The ACPI firmware must provide and implement a single ACPI power source device per section 10.3 of the ACPI specification. Some of the information described in this article is specific to Windows and is not detailed in the recent ACPI specification.
