Yesterday I installed the new firmware on my Zune 30. It worked perfectly. I was able to sync wirelessly. My Zune is about a year old and the battery life has been just fine. Last night it was fully charged.
This morning I went to turn on my Zune but nothing happened. No screen, nothing, until finally a large battery icon with an exclamation mark ! in the middle briefly appeared. I assume it was in a deep discharge state. I connected it to the PC and still nothing. A few minutes latter it finally connected. Then I disconnected it; it showed a full battery icon. It appears to be working now.
Has anyone else had this problem after the firmware upgrade?
