JBL Xtreme 3 Power Button Not Working – How to Fix

When the Power button on your JBL Xtreme 3 is not working, you’ll likely want to fix it. So to that end, we give here some reasons this can happen.  Then we have some solutions for each likely cause.

JBL Xtreme 3 Power Button Not Working: Reasons and Solutions

    1. Dead Battery.  The internal battery is empty needs a recharge for continued speaker operation. Use the included USB-C charger to do this.
    2. Faulty AC Adapter.  The power adapter charger is defective.  So replace it with a USB-C charger that delivers 5, 9, 12, 15, and 20 volts, each at 3 amps.
    3. Faulty Power Port.  The USB-C input port for charging the speaker may have damage.  So replace this if you can.
    4. Bad Battery. That battery no longer recharges due to extreme age, repeatedly overcharging, or heavy use. Replace the battery in this case with one that delivers 7.4 volts at 6.8 amp hours (50.32 watt-hours).
    5. Dirty Button Panel.  The button panel has sand, dirt, or other debris  inside. This grit can keep the Power button from making proper contact when you press it. So to fix this, clean the switches. Thus take the speaker apart and blow or brush them out.
    6. Button Panel Had Failed.  The switch panel is defective. So the solution here is to replace it.
    7. Faulty Speaker. Your speaker is beyond repair. If you find this, then the best bet is just to get a new one.
