As long as it’s plugged into the mini USB port it will play Bluetooth,sync to my computer or phone, however when there no power source, it’s completely dead ( even though I’ve charged it overnight ) and nothing I’ve tried helps!!! What am I doing wrong?

Even rechargeable batteries have a lifespan Here’s a link to the ifixit Jawbone Big Jambox Battery Replacement guide, which may be of some help. Replacement batteries are available online.
