I'm having a problem with my treo 650 where it only powers on if I wiggle the power cord a bit, and then it powers off immediately. so I infer that something or other is loose or broken that is preventing the thing from powering or charging. I've been having this problem for a while but it's only recently deteriorated to the point where the phone doesn't charge at all. is there some easy way to fix this before I junk it?
