This "chosen solution" for this question didn't work for me, but this one from CNET did. All I had to do was reset the PRAM and keep the buttons held down until I heard THREE OR MORE startup chimes. Problem resolved completely.

An in-house MacBook Pro recently began exhibiting this issue, and the fix that eventually worked was resetting the PRAM with a twist. Apple indicates that resetting the MacBook Pro's PRAM requires holding down the Command, Option, P and R keys at startup until two restarts occur. However, we found that waiting for three or more startup chimes while resetting PRAM resolved this issue where waiting for only two chimes did not.
