A:Answer You should be able to turn the speaker off after one press on the power button. While the Link 10 is not plugged in to charge, leave it turned on, and wait until it turns off. After it does, please try powering it on, then off, and see if it would work better that time. But if the speaker would still not power off, please submit a case request at www.jbl.com/support-contact.html and the customer service team will be more than happy to further assist you.
