C16 is one of those small yellow components? If so C17 is going to have nothing to do with it as it's an electrolytic. Check the value of the other ones that look like it and are next to it and the same size and shape.

thank you for your answer, yes, the yellow one. I have mentioned the C17 just in case. removing one that is still in one piece is a good idea, thx. I will come back to this after I will know the value, just to keep a track record of it.
The board is running without it but I wanted to keep it "whole".

thank you, tomas

any idea what value the capacitor could have?

Is it across one of the power rails? It looks to be, along with the electrolytic nearby. In that case anything from 10 to 100 nF will work. In fact not having it at all should not affect the mobo, it's there to filter the HF noise that electrolytics can't properly deal with due to their internal inductance.

thank you for your answer. I have extracted one of the same kind and the value is 150nF. Since I dont have this value I will order a few just in case.

thank you, for your help

br, tomas

A bit odd value but 100nF or 220nF would work just fine. It's not that critical, you can substitute with what you have on hand.

indeed 😀, anyway, I have ordered the 150nF since I had no 220nF at home, I would rather go with a slightly higher value than a lower one anyway.
the board posts without them but I will add them as soon I will get them.

thank you, tomas
