Thanks for a great tear down guide. Hi just wondering if there is a tiny battery inside like in a PC that has a bios battery ? In my case my chalk audio nest is unable to connect to wifi. I have tried ALL suggestions found online to no avail. As a last effort my plan is to open up the speaker (as you have done) and disconnect the boards to see if that somehow does an embedded reset that might enables a wifi connection fix. Or perhaps you might have another suggestion when I tear down the unit?
