After small wine spill on Thinkpad E545 keyboard, 4 keys stopped responding: “g”, “h”, “‘“ (apostrophe), and “4” on the number keypad. Other keys were malfunctioning as well in the beginning, typing 2 separate symbols at a time, but then it resolved after an alcohol “bath”.
Is there any way to revive these remaining keys? It looks like only a small section of the schematics does not work.
