Chapter 1 System Overview
1 1
Compliance with EPA Green PC Specifications
To meet the Green PC specifications, a computer system must be able to enter an
idle state (Sleep Mode) that reduces the total system power use to 30 watts or
less on the input - AC side. The monitor and printer must also use no more
than 30 watts.
Responsibility for Meeting Green PC Requirements
The system integrator is ultimately responsible for meeting all Green PC
specifications and performing the tests necessary to obtain Energy Star
approval, because the motherboard is only one component in the system.
Other components have a major impact on system power use.
Green PC Hot Keys
A keyboard hot key is any multiple keystroke operation that causes the keyboard
controller to execute a complex system function transparent to the system
operating system. The AMIBIOS system BIOS and the American
Megatrends MEGAKEY keyboard controller used in the Super Voyager
LPX motherboard provide several hot key features.
Because of the highly programmable nature of the MEGAKEY and the AMIBIOS,
configuring the functionality and keystroke assignments can be done by the
OEM. After system BIOS POST (Power On Self Test) completes, AMIBIOS
initializes the MEGAKEY keyboard controller using values preset by the
OEM via AMIBCP (American Megatrends BIOS Configuration Program).
The MEGAKEY supports hot key control of: system security locking.
System security locking is enabled by pressing <Ctrl> <Alt> <Backspace>
only if the system password is enabled in the
Advanced Setup part of
WinBIOS Setup.
Using the Turbo LED
The Turbo LED indicates if the system is using low or high operating frequency. If
the Turbo LED is on, the system is operating at high operating frequency. If
the Turbo LED is off, the system is at low operating frequency.
