Bluetooth Surface Laptop 3 disconnects and reconnects for no reason

If you're still having trouble try this Phil, its worked for me.

1 - Carry out the advice regarding going to Device Manager - Human Interface Devices - Bluetooth Low Energy GATT... - Power Management  - and uncheck Allow the computer to turn off this device to save power...

2 - Then also go back to Device Manager - Bluetooth - Power Management - Qualcomm Atheros QCA61x4 Bluetooth - click that and uncheck the Allow the computer to turn off this device to save poweroption.

Hope it works for you.  Regards.

Hi PhillipNaples,

Thank you for reaching out to Microsoft Community. We are sorry to hear about what you are experiencing on your Surface Laptop.

Please try these steps then observe if the Microsoft mouse and keyboard still disconnects and reconnects randomly:

                 While the mouse and keyboard is connected/paired, open Device Manager

                 Expand Human Interface Devices

                 Double-click on Bluetooth Low Energy GATT compliant HID device, select Power Management tab above. Uncheck the box for "Allow the computer to turn off this device to save power" then click OK. If you have multiple Bluetooth Low Energy GATT driver, please do this on all of them.

Restart Surface

Hello, I'm having the exact same issue with my bluetooth disconnecting/dropping out intermittently, multiple times each hour.

I've tried the above fix and the issue is still persisting.  Are there any other fixes or setting updates you can suggest?

I don't have a listing for Bluetooth Low Energy GATT compliant HID device on Device Manager under HID.

Same problem here.  My first unit was replaced for the exact same reason and the new one I got has the same issue.  There is clearly something wrong with SL3. I am using a Sony noise cancelling headset and a Microsoft mouse and both Bluetooth devise are disconnecting and reconnecting many times per hour.
