Missing Capacitor, but laptop still works.

I have a Mid 2014 Macbook Pro 15 Retina.

The Macbook Pro stopped working one day. When I investigated I noticed a burnt capacitor, and I removed it. The laptop started to work again and I have not noticed any problems with it at all. I have tested everything (CPU and GPU Stress tests, Memory diagnostics, Apple Hardware test, etc), and everything is fully working.

That Capacitor is still missing though. It was one of about 15 identical capacitors in a row on around the top of the motherboard. (68UF, 20%, 16V, PolyTantlum).

My question is would it be ok to not replace the Capacitor?

Do you think there would be any problems?

Update (11/03/2019)

This is not my photo, but it looks like it's in the same place on the motherboard.

(you can see a row of capacitors on the bottom part of the motherboard in the image)

Capacitors store power and smoothen power rails, do not create them. Therefore if you have 15 Caps on a given power rail it’s quite safe to just ignore and not replace a single one, as total capacitance won’t be hit that bad. I’d replace it, but it’s my job and I’m very picky.

Some cheaper labs deliberately ignore capacitors for time saving, remove bad ones and do not replace the ones they knock off boards incidentally.

@rinstein we need to see where this capacitor is located so we can determine where it belongs to. Post some good images of location with your QUESTION.

The capacitor is part of the PPVIN_S0_GFXIMVP. Those capacitors are used in a way that it shunts, or absorbs the noise making the DC signal as smooth as possible as well as voltage glitches while supplying part of the GPU. So, it is conceivable that one cap is not going to make a difference on a stable power supply. I’d replace it before the power supply rails become to noisy or unstable for the GPU

Changes made based on your image. You still want to go ahead and replace the capacitor

Yeah I would highly recommend you getting that replaced because it could cause some stress on the other capacitors and possibly cause a fire. You don’t want to leave that alone when powered on.
