'''Update:''' Never mind, it’s acting up again. Time to look for a new MacBook (it has other issues too, e.g. with the battery, and the left shift, ctrl, and option keys don’t work, and it’s just really old).
'''Original comment:''' I had the same problem with my MacBook Pro (13-inch, Mid 2010). Sometimes it would randomly shut down without warning. Sometimes I saw, "Are you sure you want to shut down your computer now?" Sometimes it would shut down during startup (but if I held down any key, it would start up completely).
I tried the same solution as above. Opened the back panel and disconnected the battery. Found the keyboard ribbon cable and the ZIF socket ([guide|6041|see step 12 in this iFixit guide|stepid=19951]). Lifted the socket hinge and carefully removed the ribbon cable.
Cleaned the ribbon cable and socket with Q-tips and rubbing alcohol. Blew out a few crevices and lightly dusted the logic board with clean Q-tips. Reinserted the ribbon cable. Reconnected the battery, screwed the back panel into place, and hit the power button.
It started up without holding down any key, and I've been typing this whole response without a hiccup. No need to replace the entire logic board, this did the trick!
