I understand the Intel® NUC does not get any light activity when you press the power button.
Please try the following information to try to fix this problem.
See if the board is getting power:
Remove the bottom chassis cover to view the board inside.
Plug in the AC adapter.
If the internal power LED does not light up, try a different AC adapter.
Just in case the above procedure worked for your computer, please try the following:
Restore BIOS defaults:
Press F2 during boot to enter the BIOS Setup.
Press F9 to load factory defaults.
Press F10 to save and exit the BIOS Setup.
Hope this information is helpful.
Please do let me know if you need further assistance with your Intel product, I will be glad to assist you.
Thanks for your help, I already removed the chassis and tried to "boot" but there were no signs of life from mainboard. Unfortunattely, I was also in an outlet to test the NUC with an other AC adapter and it didn't work. I would like to sent it back to the manufacturer can you help to do that?
This is a user-to-user support forum; not an Intel Customer Support forum. For issues like returns, you must rely on the online and offline paths for contacting intel Customer Support. Here is contact information by geography:
You can try the chat or forms services, but I recommend just picking up the phone and calling them.
You will need a multimeter to determine if the power adapter is working. Set it to DC Voltage per your meter's instructions, plug the power adapter into the wall outlet, and test with one probe inside the power connector and the other pin to the outside of the power connector. You should see +19V, or -19 volts. It does not need to be exactly 19V, and technically can be anywhere in the range of 12V to 24V without damaging the unit, but it should be somewhere close to 19V if you are using the stock power adapter.
If your power adapter tests good then you need to examine the motherboard connector. Ensure the pin is not damaged or missing, and that the connector has not been shocked loose from the motherboard. If this connector is damaged it will probably not be covered by your warranty since it would indicate abuse or misuse, but it is definitely worth attempting to file a claim anyway since it can always be argued that it should not be so easy to break, and such breakage represents a flaw in design or workmanship which is always covered within the warranty term.
You indicated that there are no led indicators that come on when the unit is connected to the power adapter. As such if there are no issues with the items listed above you probably have a dead unit. Again, you should attempt a warranty claim as long as you have not modified the unit or connected it to any unofficial power sources.
Obviously mine would not be covered by the warranty.
