Ovako na prvu mi pada na pamet izvući bateriju i resetirati bios preko jumpera. Probati drugo napajanje...

Najcesce je USB port/header u kratkom spoju, ili je prdnul koji od USB osiguraca. Nadaš se da je to, u suprotnom je upitna isplativost daljnje dijagnostike i popravka.

Ovo sve si probao: https://www.youtube.com/watch?v=e9B_HiR3a5U ?
Uglavnom se radi o ostecenim usb portovima ili o ostecenim divajsima spojenim na USB.
Ja sam imao slicno sranje kad mi je ona nozica od shielding od maticne dodirivala usb i radila kratki spoj.....

ma ploča je gola na stolu i baca tu grešku (bat ionako prvo vadim al niš od toga)
kažem optički ne vidim oštečenja a ni kratki spoj pinova usb portova
možda mi je malo nevidljiv usb-c

...možda je ploča preživjela grmljavinu a da je uletilo malo na čip od HUB-a preko nekog vanjskog USB uređaja
Treba paziti i na napomenu od MBO kad se spaja onboard USB kabel za front panel :
" Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard ! "

Imam ovdje jednu zgodnu ploču u mini ATX formatu. Došla je u banani, prvi problem je da je jedna od pločica RAMa je out. Drugi problem je da se komp nakon cca 30-60 sekundi ugasi. Ono što sam primijetio je da je regulator napona na dodir vruć, čak i kada je "komp" ugašen.

Ovo je taj regulator. Ne znam koja bi bila njegova normalna radna temperatura.

Iz utičnice "komp" kada je ugašen vuče 8W, što je malo puno previše. Imate li kakvih sugestija?

But there’s a reason. There’s a reason. There’s a reason for this, there’s a reason education sucks, and it’s the same reason that it will never, ever, ever be fixed. It’s never gonna get any better. Don’t look for it. Be happy with what you got. Because the owners of this country don't want that. I'm talking about the real owners now, the real owners, the big wealthy business interests that control things and make all the important decisions. Forget the politicians. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They’ve long since bought and paid for the senate, the congress, the state houses, the city halls, they got the judges in their back pockets and they own all the big media companies so they control just about all of the news and information you get to hear. They got you by the balls. They spend billions of dollars every year lobbying, lobbying, to get what they want. Well, we know what they want. They want more for themselves and less for everybody else, but I'll tell you what they don’t want: They don’t want a population of citizens capable of critical thinking. They don’t want well informed, well educated people capable of critical thinking. They’re not interested in that. That doesn’t help them. Thats against their interests. Thats right. They don’t want people who are smart enough to sit around a kitchen table to figure out how badly they’re getting f*cked by a system that threw them overboard 30 f*cking years ago. They don’t want that. You know what they want? They want obedient workers. Obedient workers. People who are just smart enough to run the machines and do the paperwork, and just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, the reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it, and now they’re coming for your Social Security money. They want your retirement money. They want it back so they can give it to their criminal friends on Wall Street, and you know something? They’ll get it. They’ll get it all from you, sooner or later, 'cause they own this f*cking place. It's a big club, and you ain’t in it. You and I are not in the big club. And by the way, it's the same big club they use to beat you over the head with all day long when they tell you what to believe. All day long beating you over the head in their media telling you what to believe, what to think and what to buy. The table is tilted folks. The game is rigged, and nobody seems to notice, nobody seems to care. Good honest hard-working people -- white collar, blue collar, it doesn’t matter what color shirt you have on -- good honest hard-working people continue -- these are people of modest means -- continue to elect these rich c*cksuckers who don’t give a f*ck about them. They don’t give a f*ck about you. They don’t give a f*ck about you. They don't care about you at all -- at all -- at all. And nobody seems to notice, nobody seems to care. That's what the owners count on; the fact that Americans will probably remain willfully ignorant of the big red, white and blue dick that's being jammed up their assholes everyday. Because the owners of this country know the truth: it's called the American Dream, because you have to be asleep to believe it.
