System BIOS
Table 45 lists the system states based on how long the power switch is pressed, depending on
how ACPI is configured with an ACPI-aware operating system.
Table 45. Effects of Pressing the Power Switch
If the system is in this state…
Off
(ACPI S5 – Soft off)
On
(ACPI S0 – working state)
On
(ACPI S0 – working state)
…and the power switch is
pressed for
Less than four seconds
Less than four seconds
More than four seconds
…the system enters this state
Power-on
(ACPI S0 – working state)
Soft-off/Standby
(ACPI S1 or S3 – sleeping state)
Fail safe power-off
(ACPI S5 – Soft off)

System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The
operating system puts devices in and out of low-power states based on user preferences and
knowledge of how devices are being used by applications. Devices that are not being used can
be turned off. The operating system uses information from applications and user settings to put
the system as a whole into a low-power state.
Table 46 lists the power states supported by the server board SE7210TP1-E along with the
associated system power targets. See the ACPI specification for a complete description of the
various system and power states.

safely.
Notes:
1. Total system power is dependent on the system configuration, including add-in boards and peripherals powered
by the system chassis’ power supply.
2. Dependent on the standby power consumption of wake-up devices used in the system.
