Something is happening with this board where it keeps blowing U7100 with the only resulting damage being a short on SMBUS_SMC_5_G3_SCL. When I replace it, the computer will charge normally and work on battery and then after about a day it will blow again. This has happened with different genuine batteries and different genuine power adapters. We've cycled through the problem many times thinking it was the battery, and then no, it was the adapter, and on and on. It will happen with any battery or power adapter. Was liquid-damaged originally. Any idea what might be causing something like this?

Crap under battery connector causing high voltage on data line. Worst case would be a problem inside the board.
