JBL Xtreme 2 Power Button Not Working Fix

When the Power button on your JBL Xtreme 2 is not working, this likely means one or more things.  Either your speaker is broken beyond repair, the battery inside no longer recharges due to age or heavy use, or, you accidently put your speaker into service mode a.k.a. secret or weird mode.  So, assuming that all the hardware and software in your speaker is still okay, we’ll cover here the last possibility. Thus, we describe below how to get your JBL Xtreme 2 out of service mode, and restore proper operation.

JBL Xtreme 2 Service Mode Details

First, when in this (often called ‘weird’ or ‘secret’) mode, the JBL Xtreme 2 does not power ON unless you connect an external power source such as the included AC charger adapter. Thus, it will not run on the internal battery while in Service mode.  Furthermore, when you do apply outside power, it powers up without you pressing the Power button.  I.e. It comes on as soon as you apply power to the DC input port on the back of the speaker.

Further, you cannot turn off the Xtreme 2 while it is in Service mode, unless you disconnect the external power source. And then, it powers off without pressing the Power button.  So when this service mode is active, the Power button appears to not work.

Indeed, none of the buttons seem to work in Service mode, except for the ones needed to exit service mode.  E.g. The speaker won’t pair with any devices or other speakers when you press the Pairing button, and as mentioned, the Power button does not switch it off either.

How to Turn On Service Mode

This is what you may have done by accident at some point just prior to your speaker’s Power button not working… To turn on this Service mode, power up the speaker first, and then press the Connect+ and Volume UP buttons at the same time, until the speaker powers OFF, which usually takes ten seconds or so.

Find these buttons pointed out in the next picture. Note that you can enter this mode as long as the speaker is ON, and it doesn’t matter whether it’s connected to external power or not.  Also note that these buttons are very close to (beside) each other.  So it’s easy to press them both by mistake, especially with the Volume Up button is such a heavily used control.

How to Fix the Power Button Not Working on the JBL Xtreme 2 Speaker

Now you can restore proper operation by disabling this mode. But note that when this Service mode is in effect, then to switch it back off, you must connect external power again. Why?  Because when in Service mode, the JBL Xtreme 2  won’t come on without outside power. But you can’t change modes without powering up the unit first.  Thus, you need the power adapter to make this fix.

    1. So, connect your speaker to AC power and turn on the speaker.
    2. Then, with the speaker Power button glowing, you press and hold the Connect+ and Volume UP button combo for ten seconds or so, until the unit powers off.
    3. Then, normal speaker operation returns.

Finally, at this point, the Power button should work again, whether or not you connect the AC adapter.
