Intel SHARKEY S775 I915P 10PK KD915PSYLPAK10 User Manual

The boards support a chassis security feature that detects if the chassis cover is removed.  The 
security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion 
connector.  When the chassis cover is removed, the mechanical switch is in the closed position. 

Power management is implemented at several levels, including: 
•  Software support through Advanced Configuration and Power Interface (ACPI) 
•  Hardware support: 

  Power connector 
  Fan connectors 
  LAN wake capabilities 
  Instantly Available PC technology 
  Resume on Ring 
  Wake from USB  
  Wake from PS/2 devices 
  Power Management Event signal (PME#) wake-up support 

ACPI gives the operating system direct control over the power management and Plug and Play 
functions of a computer.  The use of ACPI with these boards requires an operating system that 
provides full ACPI support.  ACPI features include: 
•  Plug and Play (including bus and device enumeration) 
•  Power management control of individual devices, add-in boards (some add-in boards may 

require an ACPI-aware driver), video displays, and hard disk drives 

•  Methods for achieving less than 15-watt system operation in the power-on/standby 

sleeping state 

•  A Soft-off feature that enables the operating system to power-off the computer 
•  Support for multiple wake-up events (see Table 11 on page 41) 
•  Support for a front panel power and sleep mode switch
