I plug my ipod in but it's not charging?

I don’t know. That happens to me occasionally. I don’t know why. My eyetv tuner doesn’t recognize the USB ports on my mac sometimes. It tells me I need to have it plugged into a USB 2.0, not 1.0 or 1.1 or whatever the error message says but my Mac USB ports are 2.0. And then it doesn’t do it. Both are intermittent problems. I don’t know what causes it. But when it happens I just charge it with the wall charger. It always syncs though, just like yours.

Did you update iTunes recently? This happened to my old iPod after I updated iTunes. I fixed it by plugging it into the USB port in the back of the computer (the big, boxy part with all the plug ports), not the monitor or keyboard.

Are you sure its not charging, sometimes the little lightning bolt doesn’t show in the battery bar of the ipod, but is still charging. Well on mine anyways.

Try soft resetting it by holding down the center button and the menu button for a while until the little apple logo comes up. Sometimes that works when mine is acting up. Does it still charge through a wall charger?

Bad cables possibly, or dirty connectors. As Allie says bypass the keyboard and plug direct. Try a new iPod cable. Or try plugging into a powered USB hub or wall charger to rule out the iPod or cable.

I had a similar problem with my IPOD. It turned out to be a bad connection in the USM/IPOD cable. I replaced the cable now it syncs and charges where before, it would only sync.
