I had my polly replaced, original one was PO206** I cant remeber last two numbers, when it was cold it took roughly 1-2 minutes to start, when it was warm it took 20-30 seconds. My new Poly po26***, boots up within 20-30 seconds all the time. If your poly does not turn on and only turns on when connected to a charger then you need to have it replaced with a newer upgraded poly. The first few polys were set to turn on when detecting a certain voltage from mojo, Chord then made changes to poly so that it turns on if it detects any voltage from mojo. If I recall correctly.
