Hi I upgraded my home routers to AC 5ghz so i decided to upgrade my laptop's built in 300mbs wifi to modern standards.
the wifi works great at full speeds consistently the bluetooth only works after a full power cycle.
if you goto sleep mode or hibernate and power back on bluetooth no longer exists.
I have spoken to online chat here and i have spent hours and days trying clean instal of windows 10 pro and upgrade/downgrade of the drivers etc
I have even purchased another adapter and it gives me the exact same problem.
I have read 100's of forums and one thing that strikes me is a whitelist for bios
is this item on the whitelist or not - is there something i can do before i get really cross with this laptop.

Thank you for using the Lenovo forums.
I would recommend that you attempt to disable the "Allow Windows to turn off this device to save power" option in your settings.
You should be able to do this by finding your "Device Manager", just search for it in your start search bar, once you got that open, find your Bluetooth device, right click and properties, and find the "Power management" tab, there should be a box that you can tick/untick for "Allow Windows to turn off this device to save power".
If these steps do not work or you would like more info on this issue you can call your local Lenovo support line. Below is the link to the phone list where you can find these numbers
Hope this help you and let us know how you get on
