1-3 ACPI/PC 98 Features
ACPI stands for Advanced Configuration and Power Interface. The
ACPI specification defines a flexible and abstract hardware inter-
face that provides a standard way to integrate power management
features throughout a PC system, which includes its hardware, the
operating system and application software. This enables the sys-
tem to automatically turn on and off peripherals such as CD-ROMs,
network cards, hard disk drives and printers. This also includes
consumer devices connected to the PC such as VCRs, TVs, tele-
phones and stereos.
In addition to enabling operating system-directed power manage-
ment, ACPI provides a generic system event mechanism for Plug
and Play and an operating system-independent interface for con-
figuration control. ACPI leverages the Plug and Play BIOS data
structures while providing an architecture-independent processor
implementation that is compatible with both Windows 95 and Win-
dows NT.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide ap-
proach to system and device power control. OnNow is a term for a
PC that is always on but appears to be off and that can respond
immediately to user or other requests.
Slow Blinking LED for Sleep-State Indicator
When the CPU goes into a sleep state, the power LED will start
blinking to indicate that the CPU is in sleep mode. When the user
presses any key, the CPU will wake-up and the LED will automati-
cally stop blinking and remain on.
