I'd personally say that since it hasn't been off for that long (less than 3
years) and since it sounds like you're not interested in taking it apart,
I'd just plug it back in, and see how that goes.

As a minimal step, I might disconnect the PSU from the rest of the drive,
and plug it in like that for a moment, but it's probably best to not run it
without a load for very long.
