Sounds like bearings. The brushes send electricity to the chopper. When you had no power the squeaking continued. Mine sometimes hum if it doesn't get a good run every once in a while...
EDIT: But I'd recommend investigating it before you run it again.
Own and love a Thunderbolt 1000 and a Model 5.
I have many hobbies and interests. And I love them all.
