I had a 512MB shuffle that I always used for working out. When I was lifting in my garage the other week, I was sweating all over my shuffle, but nothing out of the ordinary. It started to pause itself randomly, I didn't think much of it, and would just unpause it and continue lifting. Eventually, it just turned off and wouldn't turn back on. I am afraid to plug it into the USB on my laptop because I dont want to risk frying the port/fucking up my computer. It was charged at least half way before I started that workout too; it can't be a problem with the battery, can it? SOMEBODY HELP!
