what could be the issue? it still works, but I never know when it will turn on again, if ever sometimes. it restarts just fine. when i turn it off, I wait until it cools down to try to turn it back on, but it just takes awhile to start working again. sometimes it does appear to get a little hot when i'm running media and other programs at once and I turn it off. I have 16 gb of ram and a 250gb ssd in it...thanks for reading!
First of all, regarding heat, if the temperature, when under load, is not spending any appreciable amount of time over, say, 90c, then this is just fine.
As for instability, have you tried a different power supply? Replacements for every NUC model are available via places like Amazon pretty cheaply.
In addition to (not instead of) the advice given to you by Scott, I can heartily recommend you read the thread lower down entitled Dust Removal.
If you have never cleaned out your NUC you might be surprised at what could have accumulated, how easy it is to remove and how beneficial the effect is.
Worth a thought after you have sorted the current problem. Best of luck.
- I completely agree with @JRayn3 , you should undust your NUC.
- In my first NUC - NUC6i5SYH, I got similar problem. The problem was caused by Power ON switch. The switch contacts were oxidized. After removing the board, using Compressed Air Duster, I've cleaned dust from the Thermal Solution. Next I've sprayed little contact cleaner Servisol super 10, on the Power Switch (witch is installed also on the board upper site).
- In the following links, you may find explanation (an example), how to remove board from NUC housing: https://www.ifixit.com/Guide/Intel+NUC5i7RYH+Disassembly/98011 , https://www.youtube.com/watch?v=MwqrfIdyvGw&t=300s
I have the exact same problem as aluon1. It seems the power switch might be the main culprit (there is never a problem with power supply once the system is running).
Can you elaborate a bit more on where exactly you have applied the switch cleaner spray? On the physical switch on the chassis or really on the board? Anything to keep in mind while applying the spray? Sorry for the stupid questions...
And yes, I should also remove dust... 😏
Thanks a lot!
- On my NUC I saw that when I've applied more force on the Power Button, the NUC started. So, my conclusion was that there is a problem in switch contacts.
- After disassembling the board, I've sprayed disent amount of Servisol Super 10 https://www.ebay.com/itm/Servisol-Super-10-Switch-Cleaner-Lubricant-Contact-Cleaner-Mixing-Desk-Stud..., targeting the switch plunger. Since the switch is not hermetically closed, certain quantity of the cleaning solution, penetrated to the switch contacts. Naturally some solution also wetted the board and components near the switch.
