When your JBL Charge 5 Won’t Power OFF, this likely means one or more things. And we offer below a couple solutions for the most likely cause.
Now in this model, one or more of the following may cause this speaker to fail to shut down.
Now we assume here that all the hardware and software in the 5 is working correctly. So we cover below the possibilities in the last item; Service Mode and Lock Mode. Thus, we describe below how to get out of these modes, and turn your speaker OFF once again.
Now you can restore normal operation by deactivating this mode. But note that when active, you must connect external power to switch it OFF. Why? Because when in Service mode, the speaker won’t power up without outside power. But you can’t change modes without switching on the unit first. Thus, you need the AC adapter to make this fix.
Again, you can restore correct operation by cancelling this mode. But note that when Lock mode is active, you can switch it back OFF without the charger. But you can do that only if the battery is not dead.
Now you may not know battery status. So to be sure that you can power up the 5 after exiting Lock, just connect external power.
