NOTES:
1. Blink rate is ~1 Hz at 50% duty cycle.
2. It is also off when the system is powered off (S5) or in a sleep state (S1).
3. The power LED sleep indication is maintained on standby by the chipset. If the system is
powered down without going through the BIOS, the LED state in effect at the time of power off
is restored when the system is powered on until the BIOS clear it.
4. If the system is not powered down normally, it is possible the Power LED will blink at the same
time the system status LED is off due to a failure or configuration change that prevents the
BIOS from running.

LED Color State Description
Power/Sleep Green On Power on/ACPI S0 state.
Green Blink Sleep/ACPI S1 state.
- Off Power Off/ACPI S5 state.
LAN Green On LAN Link no Access.
Green Blink LAN Activity.
- Off No link.
System Status Green On System Ready/No Alarm.
Green Blink System ready, but degraded: redundancy lost such as the
power supply or fan failure; non-critical temp/voltage
threshold; battery failure; or predictive power supply failure.
Amber On Critical Alarm: Critical power modules failure, critical fans
failure, voltage (power supply), critical temperature and
voltage.
Amber Blink Non-Critical Alarm: Redundant fan failure, redundant power
module failure, non-critical temperature and voltage.
Off Off Power off: System unplugged.
Power on: System powered off and in standby, no prior
degraded\non-critical\critical state.
State Power Mode LED Description
Power off Non-ACPI Off System power is off and the BIOS has not initialized the
chipset.
Power on Non-ACPI Solid on System power is on but the BIOS has not yet initialized the
chipset.
S1 Sleep ACPI Blink DC power is still on. The operating system has saved
context and gone into a level of low-power state.
