Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Advanced power management is an API developed by Intel and Microsoft and released in 1992 which enables an operating system running an IBM-compatible personal computer to work with the BIOS to achieve power management. Revision 1.2 was the last version of the APM specification, released in 1996. ACPI is intended as the successor to APM. Microsoft dropped support for APM in Windows Vista. The Linux Kernel still supports APM as of 2.6.39-rc2, but is considering dropping support for it in 2.6.40. APM uses a layered approach to manage devices. APM-aware applications talk to an OS-specific APM driver. This driver communicates to the APM-aware BIOS, which controls the hardware. There is the ability to opt-out of APM control on a device-by-device basis, which can be used if a driver wants to communicate directly with a hardware device.show more
