This question is a year old but I am going to answer it incase someone else runs into this same issue. I just bought a mid 2011 27" refurb iMac from IBM and they scrubbed the HD completely.

Your machine is now 10 years old, so there's definitely the risk that your PRAM backup battery has "worn out" and is nearly dead now. The life expectancy for these kinds of "coin cells" is normally about 10 years. So if you disconnect your Mac from the power supply for an "extended time" you risk that it fails to back up the PRAM. A battery loses its charge ...
