Sansa Fuze+ - will not turn on, charge, reset....brand new

5 out of 15 sansa fuze+ MP3 players, which have never been used, will not charge (battery says critical low), turn on, or reset. Any suggestions? I’ve tried resetting, holding the volume button down and plugging in…

Might be this known issue.

Try everything- computer, wall chager,  press and hold power button while plugged into each device.  Leave the bad units plugged into each charging source 15 minutes even if the screen is blank.

I think you will be able to save them all.
