I'm guessing my chumby one is broken, everytime I push the power button it starts loading (circles on screen change color) and then it repeats.  After that it shuts off and I have to remove the power cord and put it back in.  I took it apart and cleaned all the parts with a microfiber cloth to remove any dust, but when a reassembled it, it just continued to fail at starting up. (Just the loading screen.)  I'm thinking its a software problem, any thoughts?  I have never dropped the system ever, it just remained on my nightstand since I got it.
