I think that I fried my VX5-591G-75RM, adding a bunch of heatsinks.

So I used non conductive, thermal epoxy, and attached some heatsinks on the main cpu & gpu block, as well as on some mosfits, and memory.

I did some benchmarking temp tests, for a few hours to see how well it kept the system cool, with a fan on it.  Everything ran cool.

Then, when I put the case on, I plugged it in, and it shut off immediately.  Now I get no light at all, when plugged in, and it will not turn on.

It turns out that the plastic bottom to the laptop, has somewhat electrically conductive paint on it.... It was touching a few of the aluminum heasinks.

What part do you think that I shorted out, and can it be easily repaired with some basic components, and a soldering iron, or butane heatgun, with some flux?

Something like this burned out my desktop cpu years ago.  I had a large heatsink, and the first time that I put the top of the case panel on, it fried the cpu.

I just hope that this is not the same issue, as that is not changeable.

Update:   It looks like no voltage coming out of the first voltage mosfit, on the charging circuit.
