Right, but there's the post before that one which is the 'Accepted Answer'.
Is it a capacitor or the 'watch battery' that may be hosed? I'm not worried in either case but if the issue becomes more troublesome it will be good to know which part I'll be chasing. Or is the 'watch battery' the capacitor?
"There is no replaceable PRAM battery in this model. This model uses a capacitor on the logic board to hold the PRAM settings."

The types are lithium although the smallest almost seem like alkalines?""
