Latest update of Windows 10 Home causing lagging to mouse/keyboard?

You have done: reformatting, uninstalling/reinstalling, rebooting, disconnecting, updating, upgrading, etc,etc, in a desperate attempt to fix lagging and freezing of your blue-tooth mouse and Bluetooth external keyboard. But nothing worked. Worst yet: software manufacturers do not readily tell, nor there is effective hope found in YouTube.

HERE IS THE FIX (which I discovered by trial-and-error):

1. Click/open: START Button > Control Panel > Device Manager > Bluetooth > Intel Wireless Bluetooth > Power Management.
2. Uncheck: "Allow the computer to turn off this device to save power".

It is a logical thing: If the "saving power" feature of the computer's Bluetooth is checked, it means that the computer's Bluetooth signal will turn off after the mouse or external keyboard becomes inactive (even for a few seconds), in order to save power. Then, it will take a while for the Bluetooth signal and mouse/keyboard to reconnect.

I hope this solved the problem, should you have it. Please let me know. Thanks.

Can't find any power management tabs for anything under Bluetooth. Has it been removed?
How do I find the status -- if BT mouse power management is on or off?

I found out just now that many PC's have removed individual Power tabs provided by Windows and replaced them with a manufacturer designed power plan.

For example, my Samsung laptop has only 3 power settings. Conserve / Average / High Performance. All options for controlling power usage of individual devices has been removed.

If I set my laptop at Maximum Performance, the Blue Tooth mouse delay issues disappear all-together.

In a way, I like not having a myriad of choices, but I don't want the laptop running at maximum performance, just to keep the bluetooth mouse from lagging.

I found the "Power management" tab now appears in items in the Human Interface Devices category.

Unchecked the option in "Bluetooth Low Energy GATT compliant HID device and Bluetooth XINPUT compatible input device", and the Blue Tooth mouse cursor and scroll lag issue went away.
