SoundLink Mini II Incessant Beeping
NOTE: I am not sure why this thread https://community.bose.com/t5/Portable-Archive/Soundlink-mini-2-keeps-beeping-on-the-charger/td-p/12... was closed out, because the issue seems rather common amongst users.
I will preface my scenario below by saying that I have two (2) SoundLink Mini I's in the house as well, but they use a different type of charging head (rounded, cyndrical versus USB Micro) on both their docking cradles and the devices themselves--almost ten years going strong and no issues like this with them). While the SoundLink Mini II device is a definite upgrade to those in terms of accessibility and sound quality, the docking cradle has actually not done as well.
I am experiencing this issue noted in the thread above now, and it seems to be related to the docking cradle itself. I got rid of the flimsy standard manufacturer USB cable and instead replaced it with a high-grade, braided one awhile back with the same voltage and resistance specs as the stock one--just better build quality. I use it to connect to the Bose USB wall outlet dongle supplied as stock. The issue is not with the cable, however, but with the docking cradle, which seemingly has a PCB in it that needs an update in firmware or the device needs to channel power regulation better through it's own firmware update. I've checked to ensure that docking cradle contact points are touching the charging pads on the device correctly, and while one was slightly more depressed than the others (remedied with a nail pick to raise it back to the correct height), they're just fine. I removed the USB charging cable from the docking cradle and put it directly into the device as an initial troubleshooting step after checking the contacts. The charge cycling audio indicators no longer cycle on and off constantly--one beep, and it's obviously on charge/sustained power. I also did a hard reset via the power button to ensure it wasn't just a programmatic behavior based on the previous contact point issue with the depressed pin (a "limp mode" if you will), but no joy. Lastly, this device serves as a PC speaker since I need nothing more and is always connected via the 3.5mm cable as well to the PC for that transfer of sound (though I could do the same via Bluetooth, the sound is clearer with a hard line cable).
So, what to do about the faulty docking cradle is the question. I could do a teardown (I have the equipment to do this correctly) to see if something shorted, became disconnected, etc., but ideally if there is a replacement program through Bose for just the docking cradle, I would rather do that instead. Looking for inputs and/or any additional remedies I haven't yet tried.
