Clip plus turns on and off

Ah, this sounds auspiciously similar to what happens when the power lead comes loose from the battery module.  If you lose the DC bus (+), upon reconnect, the Clip will turn ON, just like it does when plugged in.  It will power up randomly as power is restored.

Try and verify this, if the Clip is ON, give it a tap and see if it “winks out”.  It only takes a light tap.

Contact SanDisk Support at 1-866-SanDisk , and let them know if this is the case.  In the US, the warranty is one year, in the EU (you guys are fortunate!) it’s two years.
