iPod Classic no response

My friend gave me an iPod classic he didn't use anymore. when I plugged it in, It started to bootloop like crazy. I left it plugged in for a while and let it do its thing, hoping it would turn on. I unplugged it and plugged it back in and suddenly I'm getting absolutely no response from the iPod. No charging screen, no bootlooping, I can't even hear the hard drive spinning (which I could before and it sounded like any old hard drive should). I've been wanting a classic for years and now that I have one I'm really hoping I can fix it without opening it up. Has this happened to anyone else?
