Thunderbolts and lightning, very very frightening me
-
So we've had some brownouts this last Saturday afternoon, and then a total blackout that lasted (in my case) for nearly 48 hours. Plenty of reports of confirmed tornadoes. I count myself lucky and have been spared the worst - I don't have to go very far to see some rather impressive damage. But to jump straight to the point - despite being set up with a UPS, one of my Intel NUCs no longer powers on. The LED built into the power button blinks once every (maybe) 2.5 seconds, but it otherwise does not power on at all. I've tried long presses, short presses, disconnecting for 30 seconds, disconnecting for many hours in fact...but the same thing occurs; the power button blinks once every 2-3 seconds but nothing happens. Like it was stuck in sleep mode and doesn't want to come out of it. The hard drive still works fine, and is now in fact running in another system. But I'm left wondering if that system is truly fried. If it was, I wouldn't expect the LED on it to blink in this way. Thoughts? Options?

My sympathies. I agree with rnbergen about the probable cause. Even if the drive is still working, I would treat it with suspicion and replace it at the earliest opportunity. A surge that burnt out components on the motherboard probably stressed the disk drive as well.

If you have another NUC, just for the heck of it I might try using the other power supply once to see if it makes any difference. If the MB died, it may be mearly coincidental. I hesitate to believe a spike would cross both the protected UPS and a wall wart to kill the board, unless it was a direct strike between the nearby transformer pole and your house. You could also attempt reflashing the bios from a USB thumb drive to see if it might post afterwards. As last resort, swap memory sticks to see if it posts. Good luck ~John

Bummer - but one question - how old is your UPS? A while ago I was picking up something from a local office supply store, and the sales clerk suggested a new UPS for me (I had told him mine was 10+ years old with new batteries). He mentioned that the surge protection (usually varistors) where out over time and lose their protective qualities. I wrote APC to ask them about it, but either received an idiot response from an AI or from a human. I never really confirmed whether or not the issue is factually. Anyone else know?

Well that was the thing, there was no lightning strike anywhere near, just some brownouts during the afternoon - enough just to trigger the battery momentarily a few times, but not even long enough to make an old alarm clock (hooked up directly to the wall) to lose power.

Yes, this is the way I read your first post, and why I recommended trying a different power supply to boot with. I hesitate to think a sputtering brownout spike would get past both the UPS and the wall wart power supply to zap the MB. Hope you can get it sorted without losing the NUC.
