Listened to my jambox on the way home. Turned it off when I got home. Went in the house and tried to turn it on again and it would not come on. I was not getting voice message from the box that battery was low. But I still tried Charging it. It would not show charging indicator. Tried to soft reset it to the PC but would not enumerate on USB.
Sounds like your PC’s USB port power service fuse is blown. If you have the correct USB charger give that a try. You may also want to try a different USB cable (maybe bad) which caused the fuse to blow in the first place.
