Help! Ipod classic frozen and Itunes cannot see it.

Hello there,
And welcome to Apple Discussions!

Have you tried a simple reset of the iPod? To do this, toggle the hold switch on and off, then press and hold the Select (Center) and Menu buttons together for a couple of seconds until the Apple logo appears. If no luck the first time, be sure to try a few more times for good measure.

If that does any good, you may want to restore your iPod via iTunes. If not, it might to try and restore it on another computer if possible and then on your own.

I've got the similar issue with my Ipod classic. It occurred when I was driving in bumpy conditions and the Ipod was working at the same time. Suddenly it stopped and I thought that the battery got flat. So next day I start charging and it was not charging at all and continously said "Please wait. Very low Battery" even after couple of hours charging. And sad Ipod icon appeared with reference to this support web page. Just in case I thought that the battery connection might be and issue and opened the cover. The battery connection was ok. I tried this reset function still battery never got full and sad Ipod icon did not disappear.
So my question is if bad battery might be the reason it is frozen and I tunes cannot see it or the vibration during the bumpy driving?

I'm currently having the same issue
