The blogsphere is full of horror tales of Zune 30GB owners waking up to dead Zunes. Microsoft states that:

“We are aware that customers with the Zune 30GB are experiencing issues with their Zune device. We are actively working now to isolate the issue and develop a solution to address it. We will keep customers informed on next steps via the support page on zune.net (zune.net/support).”

One reported fix that later failed:

This fix just worked for me (apparently), and mine is back up and working.  It’s a pain removing the plastic shielding, and you have to be careful not to break the delicate connector, but once you get those tiny screws removed, the housing comes apart easily enough.

You said the battery connectors were at the top left and right, but mine were at the bottom left and right.  Did you just have the orientation wrong, or does that speak to different generations?

UPDATE********
This did NOT work, not permanently, anyway.  Initially all was well, but then I connected it to my computer to charge and sync with the software.  It almost immediately reset and is frozen again at the logo page.  No doubt I could unfreeze it again, but what’s the point if it’s just going to mess up again when I reconnect it?

It makes one wonder how well Windows 7 is going to work. 🙂

Have a Happy New Year everyone.
