Description
Power Off
Non-ACPI
Off
System power is off, and the BIOS has not initialized the chipset.
Power On
Non-ACPI
On
System power is on, but the BIOS has not yet initialized the chipset.
S5 ACPI Off
Mechanical is off, and the operating system has not saved any context
to the hard disk (soft-off state).
S3-S1 ACPI
Slow
blink
1
DC power is still on. The operating system has saved context and
gone into a level of low-power state (sleep state).
S0 ACPI
Steady
on
System
and the operating system are up and running (working state).
Note:

Degraded
System degraded:
Non-critical
temperature threshold asserted.
Non-critical voltage threshold asserted.
Non-critical fan threshold asserted.
Fan redundancy lost, sufficient system cooling maintained. This
does not apply to non-redundant systems.
Power supply predictive failure.
Power supply redundancy lost. This does not apply to non-
redundant systems.
Correctable errors over a threshold of 10 and migrating to a spare
DIMM (memory sparing). This indicates the user no longer has
spared DIMMs indicating a redundancy lost condition.
Corresponding DIMM LED should light up.1
