I have just taken delivery of a dn2820fyk NUC. I have added Crucial CMS04GX3M1A1600C11 4Gbyte ram. The Crucial website says this is 1.35 v. I wanted to boot up and upgrade the BIOS
so booted without any HDD. However, I cannot see any activity on either of two DVI monitors and I don't see any keyboard flash when I power on. I see various threads where this kind of thing has happened. I checked inside and my jumper appears to be on pins 1 & 2.
When I remove the memory I do see the memory error power button flash pattern.
I also tried to upgrade the bios by removing the jumper and using a USB flash memory device (FAT32 12Mb) containing FY0038.bio.
I see no evidence of activity when powering up in this mode. Additionally my flash memory normally indicates it's working with a green pulsing LED.
However when it is connected I see no evidence that the LED is active. It is as though the USB isn't on.
The keyboard flashes when connected and I first connect the AC, but not after the power button is pressed.
Any ideas of how to get this working are welcome.
