Aurora R10, power button broken, need solution :)

you have an Aurora R9

R9 oem motherboard proprietary LED controller header contains two pins for power switch.

to jump start, unplug LED cable and carefully short two pins transiently

R9 user reports pin 3 and 4.

Try eBay (USA) to replace the 0MF2N board

I prefer to think you'd be able to manually jump start the motherboard - powersupply on by keeping the LED header simply plugged in, then using a paperclip or staple etc, & momentarily inserting it into pin slots 3 & 4

Alternatively, disconnect the LED header, & touch 3 + 4 w/ a flat-blade metal tool (screwdriver tip etc) til it jumps on then reconnect the LED header

Alternatively use a paperclip-staple in the 24pin connector, in slots #16 Green (PSU ON) & #17 Black (Ground) , which is to say, jump those pins together momentarily long enough until the psu clicks on

@redxps630​ an aurora r10 to be precise. But what's weird is that I tried it once it worked . I powered  it off repluged all my cables and I did it again but when I tried it again. IT tried to power up for like half a sec and now nothing

@Cass-Ole​ so I tried to jump it with a screwdriver so pin 3 and 4 and nothings happening. 

in my experience, you need to reset cmos (by using the CLR CMOS jumper), then you can jump pin 3/4 again and it will work.  Weird.  in my R7 board transplanted into new case, I connect a reset switch to clear cmos pins, so I do not need to use jumper, and power switch pins to pin 3/4.  everytime I need to turn it on, I press reset once, then power sw.  try this.

@redxps630​ so I did it with my screwdriver.
First the clr cmos jumper then tried the 3 en 4 pin nothings happening. can anything happen if i touch like pin 3 and 6 together for example ?

Just out of curiosity: how did you know the board is broken? 

I am thinking you might have a bad power supply, which would explain why jumping the pin's does nothing.

Try a BIST on the PSU: BIST test.

Above all, do not jumper 3 to 6 as that will short out your +5 volt rail...

use the jumper to clear cmos.  it takes longer than a touch of screwdriver.   recommended is 5-10 sec.

@Vanadiel​ oh well i swapped from the alienware case to a H7 from nzxt everything was ok i just couldn't connect the power button from my case to the motherboard.
So thanks to the little board  (0MF2N )
I could start it. but after 1,5 years some of the pins broke.

So now i am stuck with a broken board( 0MF2N) and no computer to use because it doesn't want to start.
The psu isn't faulty i think it's a msi 850W gold fully modular.

@redxps630​ Well I did what was explained in the manual but to start it i still need to connect pin 3 and 4 together but nothing is working.

have you replaced cmos battery with a new one? that is a good maintenance step.

also

R10 user reports pins 4 and 5 (from the left) on the led controller header enabled the case power switch

@redxps630​ Well i'm sure it's ok.
I'm just a little bit scared that i maybe fried my motherboard.
Some guys said that if you connect the wrong pins together it can fry the mb

@Rawzix​ Trip your PSU for sure if you short the wrong pins together...
