JBL XTREME - No charge, no lights, nothing

I bought my speaker a year and a half ago. Recently, it totally stopped working (I stopped it normally and the day after couldn’t start it). No contact with water, no dropping, etc. and I only used the power cable that came with the speaker.

No response of the buttons (even when combined) and when plugged in all the lights stay off (so it looks like totally dead).

It did some check with a multimeter : the power cable has a voltage of 19v (as it should be), the battery only of 6.2V (nominal voltage of 7.4V, so it’s empty?) and the voltage of the battery socket is about 8V when the speaker is plugged in.

Before buying a new battery and change it, I want to make sure the problem is with the battery. Shouldn’t my speaker go on when plugged in, even if the battery is out of use ?

Is there already a fix?

@paulloed yes it should come on with the power cord connected. This is possibly an issue with the power management circuitry etc. So, you could try and see if a new battery will turn it on and will allow you to do some trouble shooting. I am certain you checked the power board etc for missing and/or burned components etc. Post some images of the boards so we can try to assist you further. Of course, schematics are unavailable. iFixitでの質問に画像を追加する方法

Actually, I only removed one radiator to access the battery socket. I have Iimited knowledge on electronics so I didn't want do go to far the first time. I will try to dismantle the speaker and take pictures of the boards :)
