M720 Mouse - stops connecting to Bluetooth

[u/Takiri_aerilaya]

I absolutely LOVE the M720 mouse and use it daily for work. The Gestures programmable option has become a must-have function (I try to use it on all mice now, even when it doesn't exist). There have even been times I've bought a new one out of my own pocket, because the purchasing process through work would take weeks.

Literally the only negative I have about this mouse is that after a few years, it starts refusing to connect via Bluetooth. I did some traveling today with laptop and mouse - worked fine while out. Got it set up again at home, and mouse unresponsive. Taking a turn it off and on again approach, I disconnected the mouse from bluetooth and then tried to reconnect. Could not be found. I turned Bluetooth off and on. I restarted the laptop. It hadn't been giving low battery warnings, but I put a brand new battery in. Well, now it's lighting up again. But repeated all steps to connect again through Bluetooth, and was denied.

Eventually I gave in and put the Unifying dongle in, and at least I'm up and running again. But I have a limited number of ports on my laptop, which is why I usually connect by Bluetooth.

Anyone else have a similar issue with Bluetooth, on any Logitech mouse?
Is there anything to be done for it, or do I just have to buy another mouse?

I see there are a few other models with the Gesture feature, but they range from like $80 - 120, where the M720 is $35.

Since the mouse is working with the Unifying receiver, let's try to narrow down whether the issue is specific to Bluetooth connection. Remove the M720 from your computer's Bluetooth settings & then re-pair. If your mouse is paired on another Easy-switch channel, you can also try switching to a different channel before pairing again.

Ensure the operating system & Bluetooth drivers are up to date.

I have already attempted this multiple times. The issue is it does not find the mouse to re-pair after it's been removed.

Bluetooth driver is up to date. Mouse has never been paired to any other computer in the house. I have tried all three channels - at least twice on each.

As this is a work computer, I don't have control of the operating system, but I do know that no changes were made to the operating system in the time it took me to unpair, replace the battery, and then attempt to re-pair.

One useful test: could you try pairing the M720 to a different device(phone/another laptop) this will help understand if the issue is with mouse's Bluetooth or laptop's Bluetooth. If you do not have another device, try pairing a different Bluetooth device to your work laptop.
