Hello Knurpht:

I had my laptop charging overnight and bluetooth did not fail, but as an
experiment I removed the charging cable and the bluetooth went out shorty
afterwards, so perhaps you and Arjen are on to something? I've rebooted
since, while plugged in I see.

Please also try this:
Use lsusb to find the manufacturor and device ID
Now edit /etc/default/tlp ( needs root permissions ) and search for
'USB_BLACKLIST='. , and add the manufacturor and device ID between quotes,
like below.
USB_BLACKLIST="04e8:3292" for example.

This should prevent the USB device to be switched off by power saving

Before pulling the power cable I saw:

$ sudo rfkill list
[sudo] password for root:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
5: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
