I have a refurbished 6GB Sansa E270 v1, will not turn on, comp (on both XP and Vista) will not recognize the device. Tried all the steps I could find, nothing will work. Only thing that does happen is the blue ring/wheel will light up, and that’s it.
Remove the rear panel and look above the battery module. You’ll see a black cover at the top section, with a grey smaller rectangle. Give this a gentle press inward, and see if you notice a click as the daughterboard snaps back into the socket.
