Hades Canyon doesn't power up - LED constantly blinks

[Alex27]

Hello,

I've bought a second hand NUC8i7HVK which worked perfectly while I tested it. During the tests I've reset BIOS and disabled the integrated graphics. Rebooted several times without issues. Then I shut down Windows, removed the top cover and replaced the SSD. Tried to power it up and it didn't boot. I placed the original SSD back but it still didn't boot. When I plugged in the cord it just flashed 2 LEDs next to the power button and didn't react to the power button pressing. Then I read the forums and removed CMOS cable for 15 minutes. Now when I plug the cord the 2 LEDS are constantly blinking very fast, they stop blinking when I press the power button, but no boot happens. Any suggestions how to fix this?

Alex27, Thank you for posting in the Intel® Communities Support.

In reference to this scenario and in order to provide the most accurate assistance on this matter, we just wanted to confirm:

When did you purchase the Intel® NUC?  

Where did you purchase it?

By any chance, do you know the specific model of both of the SSDs that you are trying to use with the Intel® NUC?

While both SSDs are disconnected and if you turn the Intel® NUC on that way, do you see the Intel® splash screen? Are you able to enter the BIOS?

Is there any particular reason why you disable the integrated graphics?

In order to try to fix this problem, we can attempt a BIOS recovery on the Intel® NUCt o the latest BIOS version 0067 following the instructions in the link below. Please try first the "BIOS Recovery by Power Button Menu" method, and then if necessary the "BIOS Recovery by Security Jumper":

NUC8i7HVK should have three-year warranty ... but even within three years, Intel warranty doesn't transfer to second purchaser ... according to what i've read!

Try to power ON your NUC in minimum hardware configuration:

1. Remove the SSD drive. Leave only one SO DIMM.

2. Press the Power Button and hold it depressed for about 3 second. Count 1001,1002, 1003 and release the Power Button. NUC should boot into Power Button Menu. 

3. If you have booted into Power Button Menu, click on F2 to enter BIOS.

4. While in BIOS, click on F9(Y) to set BIOS to default settings and then F10(y), to save settings and exit from BIOS.

A lot of people post their problems and then we never hear back to find out if the fixes worked ... I want to find out what this is!

I've tried all the suggestions and nothing helped. I am in process of returning the NUC by warranty and getting a replacement. I was fortunate to have all the docs and the warranty case approved.
