I am also waiting for the answer you will receive.
I bought it three weeks ago and tried everything I could.
Change power settings, reinstall drivers, delete and reset adapters, edit the registry, reinstall Windows(3 times), replace devices, and more.
The conclusion I found, this is a matter of the device itself. (This is not a problem caused by an update crash or other reason)
Yesterday, I proceeded with 'Restore via USB', and in the first boot.
all updates were blocked through airplane mode.
I just connected a Bluetooth mouse (MS product) and checked it.
conclusion is 'same'.
Bluetooth setting page is continuously reset, and the function repeats On / off by itself.
pairing is canceled every 10 seconds, so it is never considered to work.
Is this the 'Gacha' priced at $ 3,000? Or is all laptop3 defective?
If my Surface Laptop 3 was a $ 1000 machine, I guess I had already broken it in half and dumped it in the trash.
feel so annoying....
that I can't sleep for weeks or even work because of a software conflict or my mistake.
