Diagnostics

Instead of beep codes, errors are indicated by the bicolor Battery Charge/Status LED. A specific blink pattern is followed by flashing a pattern of flashes in amber, followed by white.

The diagnostic pattern consists of a two-digit number being represented by a first group of LED blinks (1 through 9) in amber, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through 9) in white. This is then followed by a three second pause, with the LED off, before repeating over again. Each LED blink takes 1.5 seconds.

The system will not shut down when displaying the Diagnostic Error Codes. Diagnostic Error Codes will always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic Error Codes are being displayed.

Table 1. Disgnostic LED statesThe following table provides the amber led blinking and what they indicate.
Amber LED state	White LED state	System state	Notes
2	1	CPU failure	Run the Intel CPU diagnostics tools If problem persists, replace the system board
2	2	System board failure (included 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 system board
2	4	Memory/ RAM failure	Reset the memory module If problem persists, replace the system board
2	5	Invalid memory installed	Reset the memory module If problem persists, replace the system board
2	6	System board/ Chipset error	Flash latest BIOS version If problem persists, replace the system board
2	7	LCD failure	Flash latest BIOS version If problem persists, replace the system board
2	8	LCD Power rail failure	Replace the system board
3	1	CMOS battery failure	Reset the CMOS battery connection If problem persists, replace the system board
3	2	PCI 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 If problem persists, replace the system board
3	6	SBIOS Flash Corruption	Flash corruption detected by SBIOS If problem persists, replace the system board
3	7	ME error	Timeout waiting on ME to reply to HECI message If problem persists, replace the system board

NOTE: For diagnostics pattern 2-amber, 8-white connect an external monitor to isolate between system board or graphics controller failure.
