    So, my p157sma board died. Long story short, memory cap took out the entire board and some ram, as the smc blows out through it's bottom, there's now a half-dime sized hole in the board.

    In the meantime, the replacement board I have is an older p157sm model. It is missing one to two pins, and given how the heatsink reacts to heat and other things, it seems likely that the missing ones happen to be CPU measurement for heat and or fan sensors.

    In an effort to get this working, I've looked for a solution to no avail, as my laptop shuts off with the num/caps beep, with both no GPU, and no matter the fan. So, as a result, I've floated a couple of ideas including an override via spoofing or cutting the communication, or something else to permanent physical effects. The reason I'm not caring much for damage is somewhat simply based on the fact the sm-a board is under warranty, and this board is effectively damaged already.
    So my question is this, are there any physical/firmware modifications I can do to stop the Max fan, and subsequent shutdown? Im willing to do physical modifications if need be such as running a line from one side of the board to another, or something else like cutting a trace or two. The hardware is something of small importance for myself, so that doesn't matter much at all. I just want to be able to use this computer until I can get a replacement board.

    Are you sure you plugged everything back in ok? Does it boot at all?

    It boots now. I found that pin c34 and c35 and the area around them are likely damaged though. It won't read my GTX 1070 so I'M a bit afraid it may have popped it when the motherboard popped. For sure peg_txn6 and RSVD_C35 are damaged. B32-35 and d33-35 are possibly damaged as well. Is it possible that this is preventing the UEFI card from being detected or found?

    Yeah with the amount of power they can put through the socket it could have done some damage :(
