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 ?
