[SOLVED] Tiny black component broke off motherboard. Will it work?

[LongUsername]

So I broke a component off the motherboard while trying to get the motherboard out of the case. Picture of the component to the left of where it should be. Motherboard is a Asus Z690-A gaming wifi D4.

The component has 43+ on it but I have no idea about its significance.

If I use the pc will it even work or will it just blow up my gpu or something if I even try?

Not a direct answer (full disclosure) but the most likely source for an answer is Asus. Doubt that they will be very helpful. No harm in sending an email or otherwise trying to contact them.

As an option, google "Asus motherboard schematics".

Then revise the search criteria as necessary to hopefully find the schematic for the Asus Z690 and your model in particular.

Do be careful because there can be bogus/fake sites likely to appear. Simply malicious traps that want you to download "diagnostics", "fixes", etc. If your AV software alerts then leave immediately. If possible.....

43+ marking is hard to cross to a specific part but being three-legged it's most likely a transistor and probably important for the circuit it's in. The circuit is likely to be related to the on-board audio since it's in the same area as those gold audio caps. Board mfr's like to keep audio isolated from other circuits reduce EMI noise imposed on the sound output.

It's loss might simply result in low-quality audio, or no audio, on one or more of the audio channels or output jacks.

The good news is it can be easily resoldered into place once presented to an electronics tech with just middling soldering skills and iron to do the job. The bad news is the two pads to the left of the three pads for the transistor mounting makes it appear at least one more chip component is also missing. That could be very important for the transistor to function properly once it's put back in place.

Im putting the pc back together as I figured it was something to do with audio. Hopefully it will just make the front audio jack non functional although that would be quite lucky. Fingers crossed

Even if audio is totally muffed it's not the end of the world. Just disable on-board audio in the BIOS and buy PCie sound card since your board has the slots. The sky's the limit for audio quality and features at the high end but even low-cost cards have equal or better audio quality and headers for front panel jacks.

Just booted the PC...
At first when I started playing a youtube video, my heart sank when no sounds came out of my headphones. Then I started fiddling with the mixer and then an incredibly loud noise came out and I was thinking that the motherboard is waterboarding my components or something😳. There goes the GPU and CPU. But no, the monitor just started blasting at full volume, so we have sound thank god. Also, I realized my headphones weren't even plugged in smh. Works pefectly :O

No clue what that little transistor does but I guess I don't need it.
Lesson learned: Using a pair of pliers to pull screws out of your motherboard is A-OK 👍

hmm...there's a lot of audio functions with more than just the two (left and right) stereo channels, e.g., 5.1 and 7.1 audio depending on your board's capabilities. Too, it's being fed to multiple jacks, front and rear, as well as some sort of digital output for an off-board DAC. That transistor may be required to handle one or more of those function and don't forget there are microphone and line inputs too as well as equalizer controls you may have yet to try.

Pure speculation what it may be for but it's definitely for something or it wouldn't be there. If you ever change the way you use your system you might find out what, but just enjoy what you got and worry that when it happens.

And don't forget you can always get an add-in PCIe audio card and completely disable the on-board audio. They can be found pretty cheap and are just as good, with just as many features, and include interface headers for your case's front panel jacks.

this small component is probably transistor or diode. it's probably part of an audio circuit 90% chance audio will still work without that component. and 100% motherboard will work without audio circuit.
