gigabyte gb-bxi5g-760 barebone pc,Unknown capacitor

[ying]

Hello again everyone, I would need to know the capacity of this capacitor or if possible the schematic of the board.
It is a motherboard from a gigabyte gb-bxi5g-760 barebone pc.






Thanks

That looks like it is possibly connected in parallel with the nearby 470uF 25V electrolytic on some voltage input rial (12V?). If that is the case it's probably 1uF-10uF and isn't critical

What makes you think the capacitor is faulty?

Hello, the capacitor has a crack and when I unsolder it and measure it with a capacimeter I do not obtain any measurement, as you indicate it is connected to ground and to the positive of 19v (this board is fed with a 19v charger), and tested with a capacitor of 10uf but it seems still not starting.

This board was working correctly until I connected the graphics card to its MXM port and from that moment it stopped booting, the power switch turns on, the CPU heats up and the CPU mosfet also heats up progressively but without any kind of startup. I have measured the voltage of the USB ports and it is correct.

Thank you
Sorry for my bad english

Just remove that capacitor for now or replace with whatever you like (as long as it is rated more than 19V), it is not important. Your board will boot without it, there is some other problem.

I will continue investigating what may be happening

Thanks for your help
