Intel NUC suddenly stopped booting

Hi,

I have a NUC7I7DNBE i7-8650U Quad-core single board computer that I brought last year September. I was using that on a quadrotor since Sept without any problem. Yesterday all of a sudden it stopped booting. The power LED is solid green but when I press the power button ,the computer doesn't start. I tried reattaching the RAMs ( have two), attaching just one in different slots or none, but its the same result. No peripheral device is connected. It was not overheated but I still kept it off for the night. I have also tried clearing CMOS using method here https://www.intel.com/content/www/us/en/support/articles/000005805/mini-pcs.html.

 

I did not try bios recovering yet and thought of asking here once. I had the similar problem with another NUC I have but I just did not use it for a day or two and it was gone. I dont know if the same happens this time. Can you please help me troubleshoot this issue.

 

Thanks,

Indrajeet

The Power LED being lit simply means that the power supply is providing the trickle of standby power. This does not mean that the power supply can provide the full power that the NUC needs to power on. If, when you press the power button, the fan does not begin spinning, then I would look at the power supply first. Try a different power supply. If it proves to not be a power supply issue, then you could try clearing CMOS again, this time keeping the power disconnected and the battery unplugged for at least 15 minutes. If that doesn't work, you can try doing a jumper-based BIOS Recovery.

H​ope this helps,

Hi,

You are right about CMOS. It was not a power supply issue as I have already tried two different power supplies and I was using both of them since last 8/9 months without any problem. Just disconnecting and reconnecting CMOS battery actually solved it for me.

 

Thanks for your answer.

1.    "I have also tried clearing CMOS using method here…" means that you can enter bios?

2.    Can you see the Intel NUC logo after depressing Power Switch?

Edit:

Just realized that disconnecting the CMOS battery solved your problem. Please disregard my post.

I tried the instructions but it did not work and so I could not see the logo after depressing. The problem is solved after just taking the CMOS battery wire out of its socket and putting it back in. The NUC worked fine yesterday.
