Sorry we don’t have any IFIXIT guides for the Mini Boom. Here is a good YouTube Vid that shows a person opening one up: How to open logitech mobile boombox for fixing & UE Miniboom reassembly Once you get it open you should be able to check the USB port to make sure its working using a Volt meter often the port breakdown so the battery won’t charge. If the battery its self is bad you’ll need to search the web for a replacement using the info from the battery. Good Luck!
