Harman Kardon onyx only turning on while plugged in
I've got a harman kardon onyx which is powering up with no issue trough AC Adaptor and working fine but when I disconnect the AC Adaptor it doesn't power up at all by the way battery charging with no issue and it has now around 70 percent of charge I can see the lights on the the device for battery and I can see the percentage in IOS remote App as well. Don't know why when I remove the AC adaptor it turn off and not powering up on battery mode.
I have Onyx JBL model and the battery charges with no problem the problem is when I disconnect the AC cable the Speaker turn off and doesn’t turn back on unless I connect the AC cable again and by the way when I turn back the AC cable again the battery didn't lost charge and continue charging from the point it was before I disconnect the AC cable.
Es esta una buena pregunta?
