Hello My MSB 3 isn’t charging anymore after accidentally pouring coffee over the keyboard. The tablet itself is charging but nothing happens when I plug it in over the keyboard even though it recognizes that it’s plugged in. I’ve already cleaned all connectors with isopropanol and failed. I even tried to charge it with just one battery (by disconecting the keyboard battery) but also no success. The rest of the laptop works fine. Now my question is: Would a battery replacement help? Or could it be still a different problem? I’am happy for every advice! Thanks in advance.

Replacing the battery usually don’t help, the battery rarely fails, it’s always the board.
