why does my bluetooth mouse keep disconnecting

Question

why does my bluetooth mouse keep disconnecting

Sheldon Wolfe 20

My Logitech M650 has been working fine since I bought it a few years ago. In the last few days, it keeps disconnecting. I push the connect button on the mouse, a message appears on the screen saying the mouse has been discovered, followed by another message saying it can't be connected. I tried the system settings to add a device, and pretty much the same thing happens. Sometimes, if I restart, the mouse can be connected again, but not always. I deleted and reinstalled the Logitech software, checked for Windows updates (it says everything is current).

A possibly related problem is that I keep getting a message asking if a numeric code is displayed on my iPhone. The phone connects automatically with no problems, so I'm not sure why the computer is trying to connect to my iPhone.

Both problems started appearing at the same time, within the last week.

I managed to get the mouse working. Then I started getting "Add a device" message, saying "Tap to set up your iPhone"

At the same time, the mouse stopped working.

Settings showed the mouse as connected, then switched to not connected.

I followed the instructions, but the problem persists. The computer is a Lenovo ThinkPad E14 Gen 6.

Additional information: I originally used the mouse with the older computer (Lenovo X1 Carbon) for about six months, then started using it with the ThinkPad, which I got in April. The mouse worked flawlessly with both computers until a week or so ago. I just paired the M650 to the old computer without problem.

I dug out an old Logitech M560 USB mouse, inserted the dongle, and it works fine. The M650, the one I'm having trouble with, is unusual in that it can connect by either Bluetooth or USB. While trying to make it work earlier today, I inserted the M650's dongle, hoping it would at least work that way. When I inserted it, the computer made a sound that indicated the dongle had been inserted, but the mouse wouldn't work; in other words, the M650 won't work either via Bluetooth or USB.

Your mouse might not work with the USB dongle because you need to change the Bluetooth connection to USB.

From what I've researched, you need to download the Logi Option+ (Plus) app, add your mouse, connect the USB dongle, and click the USB icon to change the connection type.

Logi Options didn't do much. I was able to switch from Bluetooth to USB, and the mouse worked fine. I switched back to Bluetooth, and have the same problems. I've been chatting with Logitech, and they offer much the same suggestions. It occurs to me that pairing the phone with the computer using Bluetooth for the PhoneLink app may contribute to the problem. I'm experimenting with that.
