Hi everyone. When I plug my ipod touch (2g) in the battery icon sometimes keeps changing from the lightning bolt to plugged it. I have tried all the usb ports. I also used a friend's computer - the icon always showed a lightning bolt - until fully charged of course. Is there something wrong with my computer? I have only had this problem for several days now. It also seems it doesn't charge properly on my computer. I did try restoring and reinstalling windows.
