Hello. I have a NUC7i5BNH. It used to work perfectly fine. I sold it and the buyer claimed DoA. I refunded, got the item back and found the following;
1 2 3
Will power on with power button, LED goes from orange to Blue. No HDMI display or USB-C video output via adapter No USB as keyboard will not show Caps / Scroll lock LEDs for example.
Things that happen;
1 2 3
After power on, the NUC power cycles back to standby (orange LED) then back to On (blue LED). Cycle continues. CPU fan will spin after a short time, board gets warm to touch. Removal of all RAM causes the correct 3 slow flash of blue LED on startup.
What I have tried;
1 2 3 4 5
Check PSU power during operation. Correct 19V Remove all power, disconnect CMOS battery for several hours Reseat RAM, different slots, entire different DIMMS, etc Remove BIOS security jumper, connect fat32 format USB as per the Intel NUC hardware BIOS recovery. No indication of BIOS flash. After a short time the NUC will return to standby.
Thread attachments;
I have dumped the BIOS three times got the same CRC check CRC64 [40023CA5E05425D0] NUC7i5BNH-W25Q64FV-Dump1.zip - BIOS File (Opens in UEFITool_NE_A59)
There is also a SPI chip on the other side of the board that I originally dumped in error I have also attached in case it is useful CRC64 [4518BADB920C0602]. NUC7i5BNH-W25X10CL-Dump2.zip - Chip on RAM side of board.
