I have an older Sansa E250 and it has been great and still works perfectly. I wamted more storage so I updated and purchased the Sansa Clip+. On the E250, I could set the ‘Sleep’ setting for 60 minutes and the setting was kept in memory unless I went in and changed it. On the Clip+ if I set the ‘Sleep’ function to 60 minutes and ‘confirm’ the setting, the next time I turn the Clip+ on, the setting is back to off. I would think the setting should be retained in the Clip+. All other functions and settings seem to work fine. I have done a factory reset and the firmware is the latest. Should I return the Clip+? Any suggestions?
