SoundLink Mini II Don't Turn On

Hi people. I have a problem with your product. Bose SoundLink Mini II won't turn on. When I plug the USB into the speaker, it flashes green once. I tried to give it a charge for the night, nothing works. I tried to do an update, but it doesn't see my speaker connected to different USB ports and different USB cables (including the original). I tried to do a Reset, but it doesn't react in any way. When I tried to turn on the Ship mode at ten seconds of holding the multifunction button, it started flashing green, and when I unplug the USB and left it on for a minute and then let it charge for one hour, it still won't turn on.
