I've done a fair amount of searching and seem to be the only one to mention this, but as I'm working with the latest firmware update for the SP3 (UEFI Firmware v3.11.760.0), I've noted that the bluetooth setting has an issue. If you boot into BIOS (Volume up, power) you can navigate to the Advanced Device Settings feature. In there, the Bluetooth enable/disable is available as a standalone setting. (If you disable WiFi, that's another matter.) Change it to disabled, a reboot shows the Bluetooth adapter is indeed disabled. Enable works fine too. However, attempt these same settings change from Powershell, and you will get the error that the 'ProposedValue' setting cannot be found on this object. Consequently, the change of setting fails. Anyone else run into this, or am I the only bit twiddler on here?
