[SOLVED]820-3662 no power, responds to SMC reset

[Jay]

G'day,

Got an 820-3662 that just stopped working one day, no liquid damage or drop damage. Right now the magsafe responds to an SMC reset but otherwise it's a brick.
Found (the hard and painful way) C7620 becomes incredibly hot within seconds after connecting power. I can say I've never felt any component be this hot on a board ever.

Curious what this could be an indication of and if someone has seen this before. Not plugging it back in as I do not want to do any more damage or melt a hole in my desk

Any thoughts?

Take off C7620 and it will work again. No need to put it back, just rip the shorted one off.

Thanks dukefawks,

Not doubting your experience but curious as to why I shouldn't bother putting a new one back?
Schematic mentions "critical" and judging from the intense heat there's a lot of power flowing there.

Also, would tinfoil deflect enough heat away from the plastic connectors next to it so they don't get damaged when I remove C7620?

Just flick it off with a screwdriver, much safer than heating everything up. As to why it is not needed I can say you can make it perfect or you can just make it work.

Heh as long as I can make it "not coming back for a power issue"

That did the trick. Mac powers on and is running ASD now. I don’t understand it but I won’t question it Thanks dukefawks
