Can my logic board by repaired easily? (pic attached)

I spilled a few ounces of protein shake on my keyboard and haven't been able to boot my machine.

I was cleaning the logic board, when I notices that one of the brown rectangle receptacles only had one silver side to it.

Do i need to order a replacement receptacle? Or is the missing silver part soldering material?

Also, a couple of the white dots on the logic board are now brown, or gone completely. Are the tiny white dots necessary for the board to run? If so, how can I add a white dot to the missing space?

Thanks so much in advance!

Is there any chance you can post a larger image? It is difficult to determine which part you are trying to show us. Also , show us where the part is located in relation to the motherboard. if it requires component repair on the motherboard, then I do have to tell you that it is not an easy repair. It will require good tools and good skills.

unfortunately I can only upload an image of 300 x 225 pixels. However, you can see which brown/yellow receptacle i am referring to here:

it is the left most yellow/brown receptacle, about 1 mm from the top of the logic board.

The photo was taken from this site:

I am willing to go to any lengths to fix it myself, so any advice is greatly appreciated!!

Thanks!

okay, it is not that easy when someone looks at a schematic:-) there has to be a bit of a reference in order to find small components like this. What are the last three of your serial number? this will help to properly identify your computer and the logic board.

it looks like this: http://p30upload.com/download.php?imgf=1...

one website said it was a ceramic capicitor... just not sure exactly which kind.

Thanks!

Tim, you were absolutely correct6. I improperly identified the capacitor. It is in fact reference designator C6990 which is a 10UF 25V 10% capacitor in a 0805 package. It is part of the DC-in Battery connector circuit. I learned over the last year to properly position attached images to identify components :-) My apologies about sending you down the wrong path. I will reimburse you for the parts that you purchased based on my erroneous identification. Please use my avatar and email me.

Can you confirm that the parts you recommended are in fact the ones I need? I attached a much better picture of the same model, working logic board, below.

I am also concerned about the size of the parts you suggested. GRM188 is a 603 package, but your diagram says 402. And, the GRM188 is 0.8mm tall, but the one i have is about 0.4mm tall. Most of the capacitors (including those closest to the one in question) are 0.8mm wide by 0.8mm tall, however, this capacitor is the only capacitor (at least on this side) that is roughly 1.6 L / 0.8 W / 0.4mm H.

The LD02 doesn't appear to be the right size either.

Would you mind checking again for me? I'm a student, and you would really be helping me out a lot.

Lastly, can i just solder the missing side? Or are the remaining parts busted?

Thank you so so much!!!

Think I should get a 603 package? Seams more like the right size. I'm a little concerned because the diagram says 402 which is the wrong size, so it might be the wrong diagram. Is my concern justified??? Thanks so much!

I am bummed, I ordered the components and none looked like all the detailed pictures of the brownish yellow, yellow, some taller, some with more of a curved metal cap, etc. instead, I got big, imprecisely cut strips of white plastic. Perhaps it could have worked... I am just limited in space on the motherboard.

Do you recommend any websites that deal with macbook components in particular?

I'd feel more confident with the repair if the capacitor had the same values as well as size/shape.

Thank you

Hi Tim, I have exactly the same problem. Could you tell which parts you ordered that didn't fit?
