System diagnostic lights

Power-supply diagnostics light

Indicates the status of the power-supply in either of the two sates:

Off: No Power
On: Power is supplied.

Power button light

Table 1. Power button LED status
Power button LED state	System state	Description
Off	S4 S5	There is in Hibernate or Off state.
Solid White	S0	Working state
Solid Amber		Various sleep states or No POST
Blinking Amber/White		Failure to POST

This platform relies on the Power button LED light blinking in an amber/white pattern to determine a failure as listed in the following table:

NOTE:

The blinking patterns consists of two numbers (representing First Group: Amber blinks, Second Group: White blinks).

First Group: The Power button LED light blinks Amber, 1 to 9 times followed by a short pause with LED off for a couple of seconds.
Second Group: The Power button LED light then blinks White, 1 to 9 times, followed by a longer pause before the next cycle starts again after a short interval.

Example: No Memory detected (2,3). Power button LED blinks 2-times in Amber followed by a pause, and then blinks 3-times in White. The Power button LED will pause for few seconds before the next cycle repeats itself again.

Table 2. Diagnostic LED statusLED light codes for component issues or failure in the product.
Blinking pattern		Problem description	Suggested resolution
Amber	White
1	1	TPM Detection Failure	Replace the system board.
1	2	Unrecoverable SPI flash failure	Replace the system board.
1	5	i-Fuse failure: EC unable to program i-Fuse	This error is only applicable for factory testing.
2	1	CPU failure	Run the Intel CPU diagnostics tools. If problem persists, replace the system board.
2	2	System board failure (including BIOS corruption or ROM error)	Flash latest BIOS version. If problem persists, replace the system board.
2	3	No memory/RAM detected	Confirm that the memory module is installed properly. If problem persists, replace the memory module.
2	4	Memory/RAM failure	Reset the memory module. If problem persists, replace the memory module.
2	5	Invalid Memory installed	Reset the memory module. If problem persists, replace the memory module.
2	6	System board error, chipset error, clock failure, gate A20 failure, super I/O failure, keyboard controller failure	Flash latest BIOS version. If problem persists, replace the system board.
3	1	CMOS battery failure	Reset the CMOS battery connection. If problem persists, replace the RTS battery.
3	2	PCIe or video card/chip failure	Replace the system board.
3	3	BIOS recovery image not found	Flash latest BIOS version. If problem persists, replace the system board.
3	4	BIOS recovery image found but invalid	Flash latest BIOS version. If problem persists, replace the system board.
3	5	Power Rail Failure: EC ran into power sequencing failure.	EC ran into power sequencing failure. If problem persists, replace the system board.
3	6	Flash corruption detected by SBIOS	Flash corruption detected by SBIOS. If problem persists, replace the system board.
3	7	Intel ME (Management Engine) time-out error	Timeout waiting on ME to reply to HECI message. If problem persists, replace the system board.
4	1	Memory DIMM power rail failure
4	2	CPU power cable connection issue	Run PSU BIST. Remove and reconnect power cables. If problem persists, replace the system board or PSU based on diagnostics run.
