Recently I tried to pair a bluetooth mouse with my T450s and... failed.
Perplexingly the bluetooth device doesn't appear in device manager at all.
I've reinstalled the intel bluetooth and wifi drivers multiple times.
I've checked all drivers and bios are upto date.
I've gone into the bios and enabled/disabled bluetooth to try and 'kick' it into life, all made no difference.
I've even replaced the wifi card with an AC-8265 and experimented with swapping the antenna.
Even after all that (with the current state being the antenna's the right way around and bluetooth enabled):
There is no bluetooth device in window device manager.
There is no 'unknown' or other device in device manager.
The windows BT troubleshooter says: "device does not have bluetooth"
I've even tried booting up an ubuntu live cd and that can't find any bluetooth either.
What am I missing? Is there some other switch that would disable bluetooth?
