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.
S4
ACPI
Off
Mechanical is off, and the operating system has saved context to the
hard disk.
S3-S1
ACPI
Slow blink
1
DC power is still on, and the operating system has saved context and
gone into a level of low-power state.
S0
ACPI
Steady on
System and the operating system are up and running.
Note: Blink rate is ~ 1Hz at 50% duty cycle.

Including, but not limited to:
 Unable to use all of the installed memory (more than one
DIMM installed).
 Correctable errors over a threshold of 10 and migrating to a
spare DIMM (memory sparing). This indicates that the user no
longer has spare DIMMs indicating a redundancy lost
condition. Corresponding DIMM LED should light up.
 In a mirrored configuration, when memory mirroring takes
place and system loses memory redundancy. This is not
covered by the second bullet above.
 Redundancy loss such as power supply or fan. This does not
apply to non-redundant subsystems.
 PCI Express* link errors.
 CPU failure/disabled – if there are two processors and one of
them fails.
 Fan alarm – Fan failure. Number of operational fans should be
more than the minimum number needed to cool the system.
 Non-critical threshold crossed – temperature and voltage.

Blink
Non-critical
Non-fatal alarm – system is likely to fail
Including, but not limited to:
 Critical voltage threshold crossed.
 VRD hot asserted.
 Minimum number of fans necessary to cool the system are not
present or have failed.
In non-sparing and non-mirroring mode, if the threshold of ten
correctable errors is crossed within the window.

Critical, non-
Fatal alarm – System has failed or shut down.
