I use Yoga 370 Model 20JH002KMZ with Thunderbolt 3 Docking Station. Connected with USB-C Cable (Original).
I use external Wireless Bluetooth Keyboard (Lenovo KT-1255) and Logitech MX Master Mouser Bluetooth.
All Items are brandnew.
If I disconnect USB-C Dock-Cable, alle Bluetooth Devices (Keyboard and Mouse) are disconnecting and don't work.
Windows 10 shows both Devices as "Connected" and the Devices themselves are "blinking" (searching Notebook).
I tried this:
- Windows Bluetooth Device-Manager, disabled "windows can set device to energy save"
- Drivers are all up-to-date
- Drivers re-install
- Thunderbolt Firmware Update (up-to-date)
This all brings no solution. All Devices disconnecting if I disconnect the USB-C Docking.
Only solution I found is:
- FN-F10 multiple turning Bluetooth off and on in Windows.
- It needs often 3-4 turning off-on's until it works again.
What can I do?

Update Version BIOS:
UEFI/BIOS: ROHT 35W (1.15)
After Installing the new BIOS, I de-installed all Bluetooth Drivers and -Devices.
Restart, and New Installation of them.
It's a little bit better - if I undock Thunderbolt3-Docking, the Bluetooth Mouse/Keyboard stayed connected in most of the cases.
If I do a undock and walk away without taking my BT Mouse/Keyboard with me and come back after one hour, I'm unable to reconnect them. Then I turn 3, 4, 5, 6 - times BT off and on with some time between switching off and on.
If I'm lucky BT devices come back - If I'm unlucky they don't and I have to restart complete Windows.
All devices are shown als "connected" but the aren't really. Keyboard and Mouse are blinking, who says "searching Notebook". (Switch "BT-Devices can see Notebook" is on).
Anyone have this same effects?

Deactivation of "Windows can suspend this device for power saving" don't help me.
If I go away with my Yoga 370 and come back 1 hour later, BT-Mouse and -Keyboard don't work.
In Bluetooth-Settings the two Devices are "Paired" but not "Connected".
If I switch off and on Bluetooth on Yoga it works for some seconds, then again don't work.
I have to switch it 5 to 10 or more times off and on to get it work.
Safest way to get it work is to shutdown fully my Yoga and restart.
I have newest Drivers and new Keyboard and Mouse.
Does anyone have same Problems? Or is this a hardware issue?

I have exactly the same Problem! Turning Bluetooth on/off helps for some seconds. Newstart holds a little bit longer but does not sove the problem.
Is there no solution for this; like this I can not work with mouse or keyboard....
