After some quick diagnostics resulting from a battery that would no longer charge (flashing red power LED) when charging adapter connected, I figured the battery was shot and would no longer charge as the voltage was likely below the system threshold. After installing a new battery ordered from ifixit, all of the LED lights come on. When I plug in the power adapter, the battery does not appear to be charging and ll light remain illuminated until I remove the battery.
Try resetting the speaker with the mute button and see if it fixes the issue: Connect the speaker to powerPress and hold the Mute button for 10 seconds. The LEDs will flash briefly.Press the Power button to turn the speaker back on If you are still getting the same LEDs illuminated, and can’t get the system to power on properly after this reset, it could be a miscommunication between the LEDs and the battery.
I bought some faulty soundlink mini 1s and established all lights on with a charged battery indicates a faulty main PCB.
i have the same problem replaced battery and the blinking red light is still on
Press the sound mute button for 10 seconds while the sound mini link is NOT plugged in. Worked for me.
