Random Power issues
by business_kid from LinuxQuestions.org on (#6G0H5)
I was having uefi issues recently and this problem appeared. The box would cut off and restart - like there was some relay clicking out. There is a relay. The power button is momentary, so it must be bridged by a relay. I had one of those cheap pc builder's psus, but it died so I got a decent 750W.
/Power died just now but I managed to recover the post. My cpu fan never stopped spinning, but there was a switching type sound as it died, just like when the cpu fan cuts out.
Where was I? Yes, I got a decent 750W replacement. This happened three times within 5 minutes each in the morning, then it lasted about an hour, now it might last all day.It was frustrating during the EFI madness to go for a break and find windows when you come back. I can't link this to load, and this computer never breaks into a sweat anyhow.
/Power died again, screen goes black and we go through the 'power up' routine. I had 20 minutes running then.
As you might understand, this pisses me off. The mains power is not dying. No work going on here, and my RazPi runs 24/7 because it's only a few watts and switching it is awkward for me. But if it's powered off, it sticks on a login screen. The mains is OK because it stayed on.
I don't know whether the switching sound I hear from the pc is a cause, or a by-product of the problem. The the CPU fan doesn't actually stop but that would take a few seconds.I haven't even noticed it slowing. It's on 12V, iirc. (It's been on for an hour now, and still going).
