Missing SMC Resistor on Mac Mini board

Hi, a while ago I opened my Mac Mini and a SMC Resistor (I think) fell out of the chassis and I have just got around to finding where it’s missing. It seems to be labeled “d L8p” and I can’t seem to find it on Google. I’ve attached images of the board.

Unfortunately, I lost the part. I believe it was that same capacitor (there's a whole bunch on the board), Mine is the Mac Mini 2011 2.5GHz, and when I compare the board here: Mac mini A1347 (Mid 2011) 2.5 GHz Logic Board it's almost exactly the same (coin battery is in the same place). The capacitor is there.

I don’t have the best camera in the world but I hope that’s good enough. Let me know if you need a zoom on a certain section. I should add that I was running the mac headless (through VNC, which does work) after the board stopped displaying out, but I want to repurpose it again

Well, I’ve got some news for you the part you circled is not a resistor it’s a capacitor. If you have something loose the part is not always present on the logic board where you pointed to as you can see here:

Can you post an image of the part you have so we can see if we can identify it.

这个答案有帮助吗?

I forgot to mention, the graphics stopped working after that fell off. I tried HDMI, Displayport and USB to HDMI and none of them even got a signal.

@reedhaffner - Thats not good ;-{ This is an EMI noise suppression cap. I think you have a deeper issue here.

Lets get a full board picture of both sides at the highest resolution you can do so we can zoom in a bit without loosing the details. Look at the picture I posted as a reference.

Sadly, I don't seen anything missing on either side other than the cap. This version had issues with the Radeon GPU failing. At this point your only option is to live with it as you had or look at getting a replacement logic board. The last option which is a gamble is finding someone who can replace the cap as well as diagnose the cause of the display output failure if its something other than the GPU chip its self.

@reedhaffner I realize that this is an old question but just for completion sake. The component is a Diode. It is a 40V 200mA schottky diode in a SMBG package

@oldturkey03 - Sorry its a tantalum cap not a diode look again.
