Green PC Features
The American Megatrends Super Voyager VLB-III motherboard has been designed with the EPA Green PC
specifications in mind. The Green PC features include:
• a low power chipset,
• Sleep Mode, which allows the system to go to a low power consumption mode of operation when
the PC is idle,
• a special two-pin header issues a TTL level signal used to turn off the auxiliary AC power
receptacle on Green PC power supplies while in Sleep Mode,
• a special 10-pin header can be connected to the feature connector of a standard VGA Controller
card. A signal from this header drives HSYNC, VSYNC, and Enable Video Low during Sleep
Mode. If a Green PC monitor is used, the monitor switches to its own low power mode during
Sleep Mode.
