Thanks for suggestion. I have uncheck all the "Allow the computer to turn off this device to save power" checkboxes of all items under "Universal Serial Bus Controllers" but did not work for me. My Computer is Lenovo Yoga 2 Pro (Intel Dual Band Wireless
AC 7260). After updating to version 2004 my bluetooth device "Power Management" tab disappeared but this option has solved mouse issue on version 1909.
Edit:
When mouse freezing at the same time the bluetooth icon on the system tray disappear and then back again for a moment. I checked Event Viewer just after the mouse issue occured and I saw there is some log related to bluetooth as below:
(Event Viewer -> Windows logs -> System)
Warning / Event ID: 2 / Source: HidBth
Bluetooth HID device either went out of range or became unresponsive.
Warning / Event ID: 34 / Source: BTHUSB
The local adapter does not support an important Low Energy controller state to support peripheral mode. The minimum required supported state mask is 0x2491f7fffff, got 0x1fffffff. Low Energy peripheral role functionality will not be available.
Maybe someone has a idea about these event logs.
