Hello there everyone,

I had a resister disintegrate on a motherboard. Nothing left to identify it. Even if I knew how I couldn't because nothing is left of it. Please see pictures indicating the resister I need to replace. I don't know what a suitable replacement would be.

looks like a diode
likely is a diode.

even the marking indicates it as a diode. D6 .

that makes since because it doesn't look like any resistor I can find.

That's likely because it isn't a resistor 😀
and I can't tell from the photos if it's actually burnt or not.
looks like a typical 1N4148 diode though might be something different.

those are just example photos for the diode that should be there. the one being replaced is completely gone.

if i put a 1N4148 diode in and it isn't the right one, do i risk anything?

Diodes have a 'polarity', so you have to put it in the correct way.

I guess worst that can happen is it blows up again.

Diode, by the way it looks and the marking (drawing that's visible) underneath. There seem to be a 48 on it in the first picture, so it could be a :https://en.wikipedia.org/wiki/1N4148_signal_diode. Mind the polarity (cathode, the black strip on the right side).
