Sansa clip turns off immediately after I turn it on

As soon as I turn on my sansa clip, it turns off by itself. I see the screen/what is currently playing for maybe a split second before the goodbye screen appears. The battery life is a little more than half and no sleep mode is set. I have already tried charging/resetting it. Please help.

I would contact SanDisk Tech Support directly. It doesn’t sound like something that can be fixed either by formatting or re-installing the firmware and that’s about all you, as a user can do.

If it’s still under warranty, and Tech Support can’t help, they can set you up with a replacement.
