The S5 state is equivalent to an operating system shutdown. No system context is saved.

6.12.3Wake Events

The system BIOS is capable of configuring the system to wake up from several sources under a non-ACPI configuration, such as when the operating system does not support ACPI. The wake up sources are described in Table 27. Under ACPI, the operating system programs the hardware to wake up on the desired event. The BIOS describes various wake sources to the operating system.

In legacy mode, the BIOS enables or disables wake sources based on a switch in Setup. The operating system or driver must clear any pending wake up status bits in the associated hardware, such as the Wake on LAN status bit in the LAN application specific integrated circuit (ASIC), or PCI power management event (PME) status bit in a PCI device. The legacy wake up feature is disabled by default.

6.12.4Front Panel Switches

The BMC forwards the power button request to the ACPI power state machines in the chipset. The button signal is monitored by the BMC and does not directly control power on the power supply.

The power switch behaves differently depending on whether the operating system supports ACPI. If the operating system supports ACPI the power button can be configured as a sleep button. The operating system causes the system to transition to the appropriate system state depending on the user settings.

6.12.4.1Power Switch Off to On

The chipset may be configured to generate wake up events for several system events: Wake- on-LAN, PCI Power Management Interrupt, and the Real-Time Clock Alarm are examples of these events. If the operating system is ACPI-aware, it programs the wake sources before shutdown. In non-ACPI mode, the BIOS performs the configuration. The BMC monitors the power button and wake up event signals from the chipset. A transition from either source results
