button. The operating system causes the system to transition to the appropriate system state
depending on the user settings.
4.9.3.1
On to Off (OS-Present) or OS to Sleep
If an operating system is loaded, the power button switch generates a request via the system
control interrupt (SCI) to the operating system to shutdown the system. The operating system
retains control of the system and operating system policy determines if the system transitions
into S4/S1 or shuts down.
4.9.3.2
Sleep to On (ACPI)
If an operating system is loaded, the power button or Wake on LAN (WOL) can generate a wake
event to the ACPI chipset and a request (via SCI). If system wakes up from S4/S5, the BIOS
POST is completed and then control is given to operating system to wake up the system. If
wakeup is from S1, the operating system will wake up the system.
