Hi,

I had a similar problem with my 30GB Zune. The first normal solution is to make sure that the USB port is providing enough power to the Zune to charge it by trying a different port or computer, but since your other Zune charges it is likely not the problem.

Other possibly solutions are performing a hard reset on the Zune (hold back and up until it resets), or allowing the zone to completely discharge and try again. In my case, none of these solutions worked and I was forced to send my Zune in for a new battery, which Microsoft was willing to replace for free.

well it seems that u have the problem of power supply and u need to repair it and if it wont help replace it feel free to ask again thank u.

have you updated it to the latest firmware? cause zune's had a major malfution to to this years "leap year" the time change/date change messed with the internal clock causing major malfunctions
