    Turns out, the logic bored was fried from a bad battery. Rossmann Repair Group in New York replaced the logic bored for me for about $400.
    Thanks for posting back. Very unusual that the battery fried the logic board. And, by the way, the $400 you paid out was not out of line considering the work that was done.

    I agree!
    $400 isn't bad.
    But a bad battery doesn't fry a board like this.

    It has protective devices in it.
    I have fixed many.
    Let alone trained all the youtubers in this stuff.
    But can't mention names others have.

    But heck!
    It's fixed.
    Just way too much for that repair!

    I find that a bit odd, I wouldn’t have thought a bad battery could get so hot. Was the fan working? Wouldn’t one notice if it got that hot?
    I used to be conceited but now I'm perfect.

    Yes.
    In fact any Li-Ion battery charge system must have a thermal cutoff. It is present in all Lithium Ion battery charge circuits, and some devices have it built in the battery itself, you must wire up. Even tiny chinese 5v battery and chargers have them. That little 2 wire cutoff switch you find between the batteries when you take the battery pack apart.
