NUC7i5BNH Will not power up

Hi, 

I have a NUC7i5BNH which until recently ran well. Right now it will not power up. When plugged into the  power supply I get a solid green LED (not flashing) and the power button panel does not light up. 

I have tried the following:

1) Swapped the power supply with one from a working device and visa versa. 

2) Swapped the RAM with that from a working device. 

3) Swapped the m.2 drive with that of a working device

4) Tried a fresh SATA drive 

5) I have checked all the cables are securely plugged in

5) the fan is clean.

 

Is this device dead or is there something I have missed?

 

Thanks

Tim

Hi Tim,

You did everything  well. However if you know to reach the cooling fan (i.e. you know how to remove the board), I would try to disconnect the CMOS battery connector and reconnect it after 15 minutes.

Try also to hold the Power Button for 3 seconds (count 1001, 1002, 1003, 1004) and then release it. The NUC (if it is live) should boot into Power Button Menu.

Hi Leon, 

I tried both of these with no change in outcome

I noticed one of the wifi connectors had come off, so trying again out of desperation.

Does this mean the MB is dead?

Thanks

Hi Tim,

If only the STBY LED is lit could be that the board is dead. I would still try if the problem is not caused by fault in the Power Switch. I saw already NUCs with contaminated contacts causing power ON failure. Please refer to the Technical Product Specification . On page 46 you will see item "A" - Front panel header connector. On page 51, para. 2.2.4.4 the header pins are identified. See para. 2.2.4.4.4 describing that momentary contact between pins 6-8 should replace the Power Switch functionality.

Hi Leon, 

I take a look at this and let you know how it goes.

I left the mb plugged in and it had warmed up (the fan was not running though. 

Will try your suggestions now.

Thanks

We are deeply sorry to hear that our recommendations didn’t make any changes, in this case, based on the information provided and the troubleshooting completed, we consider that there is something wrong internally speaking with the NUC; therefore, our strongest recommendation will be that if you are within the first 30 days from the date of purchase for this unit, try contacting your place of purchase to check the warranty options for your system; otherwise, try contacting us directly to check what will be the warranty options available for your unit; feel free to refer to this post once you contact Intel Customer Support.


Here is our "contact us" information:

Hello Tim5,


Thank you for posting on the Intel® communities.


You can determine if your warranty is still active here: Determine if Your Product Is Still Under Warranty, normally it takes three years since the day of purchase so your warranty period expires with us, in case it hasn’t you will need to contact Intel Customer Support to initiate the RMA process.



Chat service here: Intel Customer Support Chat, but understand that this service is offered in English only and it is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.


Phone service:



Important note: In case your warranty period says that it has expired please bear in mind that Intel Customer Support can check for the possibility of an exception if you can provide a copy of the invoice proving that you purchased the unit less than three years ago.


*We will proceed to close this thread; however, if you need any additional information you are more than welcome to submit a new question, just bear in mind that this thread will no longer be monitored. 


Best regards,
