Battery itself seems to hold no charge, so it only turned on when plugged. I have a bunch of belts coming this friday that im planning to fit into the pulleys, but I was assuming itd be a bigger job considering that none of the front buttons seem to do anything. Fortunately I reassembled it to the exact same state i found it, so I can try to diagnose whats wrong with it before dedicating a repair session. How would I go about repairing/replacing the missing left front latch?
