Ah, perfect! Thanks! I'll update everyone when the parts have arrived and have been installed. I'll be replacing both of them just in case the other went bad too.

Alright, I’ve just finished replacing the 2 components on the board. The charred one, and the other identical one just in case it was dead too. 
Unfortunately, it still seems to sad Mac a bit but not as often and it still won’t run off the battery. It also still won’t run off the hard drive either. 
I’ve taken a picture of a few of the sad Macs it gives me to see if we can pinpoint the issue. There may be more but these are the ones I see every so often. I have reasons to believe that @techknight was correct about the Hybrid Board being the fault although I can’t see any visibly broken traces. Could there be traces on the other side? 
Let me know what you guys think!
