This is a Known Logitech Issue with the MX mouse. [URL] Its not a dell support issue.
2 new Dell G5 5000s are having this issue. Bluetooth suddenly stops working (Logi MX mouse stops moving, iPhone XR connected to Dell can't be accessed). go to Control Panel, it shows devices still paired, but when I click the Bluetooth on/off switch, IT DISAPPEARS. In Device Manager, Bluetooth is missing. If I download and re-install the Bluetooh driver, everything works again... for about a week. (Yes, mouse has 90% battery, and on the other machine, using the mouse dongle.. the mouse keeps working but bluetooth still dies.) Any help is appreciated!Thanks in advance.
