No Power on whatsoever, battery or magsafe.

Ouch... I don't like the sound of this one, but let's see what we can do.

You do say that you attempted SMC reset, but I can see why you would be unsure if it worked. Just to be sure, lets do Apple's steps:

1. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

2. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

3. Release all the keys and the power button at the same time.

Press the power button to turn on the computer.

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Now if we have a no go there, here is what I suspect and would do to check.

Almost sounds like something happened either to the logic board, or somewhere along the lines of where the power delivery systems. What has me most worried about it being the logic board is the fact no Magsafe adapters light up at all.

So my plan of action would be:

Disassemble and search for any fried parts of the logic board, while also checking to make sure all the cables and connections are nice and snug. Just make sure you follow good procedures for that in regards to static discharge, as you don't want to end up damaging anything else.

Good luck!
