I have the exact same thing happening. Only had this 8 months and the battery wont hold a charge, then on to it wont turn on at all. Is it because Bose is making these out of Mexico that there are so many issues with these? I wouldn't expect to pay so much to get such an unreliable product that $@$** the bed after 8 months.
I have bought Bose speakers for 22 years now but am strongly reconsidering that for all of my audio needs from here on in if this isn't properly resolved. I am military and word of mouth working with so many people travels fast. This speaker has let me down lots of times in front of lots of people at several functions. I would expect this from a entry level speaker, not Bose
