I’ve been grappling with this issue for ages. We moved house, and with the Roam off the charger, I didn’t set up the Sonos for a little while and when I did so the charge had drained, and then the dreaded orange light. I tried all of the suggestions here, tried various chargers, including high powered ones, but to no avail. But as some suggested, I contact support, and after going through the steps to ensure it was dead, they agreed to send a replacement. Can’t really argue with that, fingers crossed I have better luck with the replacement!

Mine is working perfectly since the replacement. They sent a Roam 2.
