Could someone please help me identify the piece (circled in the picture below)? And should I worry about replacing it? Very much appreciate it.
Looks like a diode but I can't really tell. It's also possible that the SMT pads were damaged when the part was knocked off. Can you get a closer picture of the logic board(or graphics card) and the part itself?
The good news is that's a video card. Bad news is looking at the picture I can't even see what the component is. Can't tell if that's a power regulator or not.
Whatever it is, it's connected to ground. Based on the package style, I'm going to guess that it's a non-polarized polymer cap of some kind.
You might be able to re-attach it if you add some fresh solder blobs to the contact points on the board and then, using a pair of tweezers to hold the component in place, using a very hot soldering iron to repair the connection. Be sure to unplug the nMP's power cable and discharge all residual power in the caps by pressing the power button when unplugged before you attempt this.
Thank you for your response. So far there's no notable difference - do you know the consequences of me leaving it as it is?
English please? Lol. I have no idea what that means...or why it's important.Looking at the TI data sheet ( Fig. 46 ) for the the TPS54622, the missing part appears to be the Output Filter Capacitor.

Based on paragraph 8.2.2.3 Output Capacitor Selection in the data sheet, this part is important.
Couldn't you go to apple store and have them replace it?Here it is up close. The circled thing came off on one of the boards. Thanks so much for your help! View attachment 617728

I took another picture. Hope this one is clearer. The circled thing came off on one of the boards. Thanks again!

As long as the part doesn't have the silver metal part ripped off either end, it can be easily soldered back on by anyone competent with a small soldering pencil.

Oh ok that makes sense.would that damage other components of the computer?The paragraph in question basically means that power may spike under certain situations, and the cap is supposed to be there to catch and briefly store the excess power. When that cap isn't there, that power spike has nowhere to go, kinda like plugging the drain in your bathtub, and so it backs up into the path of least resistance...which in this case refers to the components it can reach. The potentially sensitive-to-power-spikes-of-this-nature-that-the-capacitor-in-question-is designed-to-protect components.
So, to sum up, BAD JUJU.
