To fix Bluetooth pairing on a Logitech M720, select your intended channel, hold the side connect button for three seconds until its light flashes rapidly, then select M720 Triathlon Mouse in your device’s Bluetooth settings. A brief press only switches channels; it does not start pairing. If connecting still fails, check the battery and restart Bluetooth before replacing the saved pairing. The Windows steps below use Windows 11 menus.
The short version
- Pairing mode: Hold the side connect button for three seconds until the selected channel flashes rapidly.
- Power and distance: Check the AA battery and bring the mouse close to your computer, away from a nearby Wi-Fi router.
- Saved connections: Forgetting the mouse removes its saved pairing so you can pair it again.
- Alternative connection: Use the paired Unifying receiver to bypass Bluetooth.

Check the channel and mouse power
Turn on the M720 and briefly press the side toggle/connect button below the numbered indicators to select channel 1, 2, or 3. Hold that same button for three seconds until the selected channel flashes rapidly. Keep that channel selected while you complete pairing on your computer or tablet.
For a new mouse, remove the battery pull tab. Switch the mouse off and back on, then try pairing again. If power is weak or absent, replace the single AA battery in the underside compartment, following the polarity markings.
Bring the mouse close to the computer while pairing. Move both away from a nearby Wi-Fi router and retry, since Logitech identifies strong nearby Wi-Fi interference as a possible cause of pairing failure. Once the channel flashes rapidly, complete the connection using the steps for your operating system.
Reconnect the mouse in Windows
On Windows 11, open Start > Settings > Bluetooth & devices. Turn Bluetooth off, wait 10 seconds, and turn it back on. If your laptop has a physical wireless or Bluetooth switch, enable it too.
Press Windows + A to open Quick Settings and turn off Airplane mode. With the M720 in pairing mode, enable Bluetooth and select its Manage Bluetooth devices chevron. Under New devices, select M720 Triathlon Mouse, then select Done when pairing finishes.
Removing the mouse deletes its saved pairing from Windows. If an existing mouse entry will not connect, on Windows 11 open Start > Settings > Bluetooth & devices, find the mouse, and select More options > Remove device, then Yes. Put the intended mouse channel back in pairing mode, select Add device > Bluetooth, and select the mouse.
On Windows 11 builds with expanded discovery, open Start > Settings > Bluetooth & devices > Devices. Under Device settings, change Bluetooth devices discovery to Advanced and search again. If that control is missing, continue with the updates and adapter checks below.
Fix persistent Windows Bluetooth problems
On Windows 11, select Start > Power > Restart, then try pairing again. On a supported Windows 11 installation, open Start > Settings > Windows Update > Check for updates. Install available updates and restart when requested.
Next, open Device Manager > Bluetooth, right-click the computer’s Bluetooth adapter, and select Update driver > Search automatically for drivers. Restart afterward. If Windows finds no newer driver, use the PC manufacturer’s official support page for your exact computer model.
When Bluetooth controls have disappeared or are grayed out, hold Shift while selecting Start > Power > Shut down. Wait one minute after the computer turns off, then turn it on again.
The M720 requires Bluetooth Low Energy. For a Windows adapter that exposes firmware information, open Device Manager > Bluetooth, right-click the adapter, and select Properties > Advanced. Under Firmware, an LMP value of at least 6 indicates Bluetooth Low Energy support. An older Bluetooth Classic-only adapter cannot pair with the M720 over Bluetooth; use the Unifying connection described below instead.
Refresh the connection on Mac
On a Mac using System Settings, open the Apple menu > System Settings > Bluetooth and enable Bluetooth. Put the M720 in pairing mode, hover over the mouse, and select Connect. For an existing pairing, you can also open Control Center > Bluetooth and select the mouse.
On macOS 13 or later, switch Bluetooth off in that settings pane, wait approximately three seconds, and switch it back on. A Mac desktop won’t let you turn Bluetooth off when its only mouse, keyboard, or trackpad connects over Bluetooth, so skip this step in that case. Try connecting again before removing the saved pairing.
Forgetting the mouse removes its saved pairing from the Mac. If reconnecting fails on macOS 13 or later, open the Apple menu > System Settings > Bluetooth, hold Control while clicking the mouse, and select Forget. Put its intended channel in pairing mode again, then select Connect.
If the problem persists on a Mac with Handoff, open System Settings > General > AirDrop & Continuity, temporarily turn off Allow Handoff between this Mac and your iCloud devices, and retry the mouse. Older versions of System Settings name this pane AirDrop & Handoff. You can also open the Apple menu > System Settings > General > Software Update and install the compatible update offered.
Pair again on a Chromebook
On a Bluetooth-capable Chromebook, put the M720 in pairing mode, select the time, open Bluetooth, and enable it. Select + Pair new device, choose the mouse, and complete pairing. Confirm that it appears under Currently connected.
Forgetting the mouse removes its saved pairing from the Chromebook. To replace a failed connection, select the time, open Settings > Bluetooth, select the mouse under Previously connected when necessary, and choose Forget. Re-enter pairing mode on the mouse and use + Pair new device again.
If the connection still fails, select the time, open Bluetooth, turn it off and back on, then restart the Chromebook. On a Chromebook still receiving updates, connect to Wi-Fi, select the time, and open Settings > About ChromeOS > Check for updates. After the download, select Restart in the update notification.
Reconnect on iPad or Android
On iPad, put the M720 in pairing mode, open Settings > Bluetooth, and enable Bluetooth. Select the mouse under Other Devices. If an existing connection has gone idle or out of range, bring the mouse nearby, switch it on, and click it.
Forgetting the mouse removes its saved pairing from the iPad. To start again, open Settings > Bluetooth, tap the information/actions button beside the mouse, tap Forget This Device, then tap Forget Device. Put the M720 in pairing mode and select it again. Use Settings to toggle Bluetooth, since the Control Center Bluetooth button primarily disconnects accessories.
On a Bluetooth Low Energy-capable Android device, put the M720 in pairing mode, swipe down, and touch and hold Bluetooth. Enable it, tap Pair new device, and select the mouse. For an existing pairing, select the mouse under Saved devices; manufacturer menu labels can differ.
Forgetting the mouse removes its saved Android pairing. On Pixel-style Android settings, open Settings > Connected devices, find the mouse among your saved Bluetooth devices, tap the settings icon beside it, and tap Forget. Re-enter pairing mode and tap Pair new device to add it again.
Reconnect in Linux GNOME
On Linux with the GNOME desktop and a working Bluetooth Low Energy adapter, open Activities, search for Bluetooth, and open Bluetooth. Enable its switch, put the M720 in pairing mode, and select it under Devices. Wait for the status to read Connected.
Removing the device discards its saved pairing. To replace a failed pairing in GNOME, open Activities > Bluetooth, select the mouse, and select Remove Device. Put the mouse back in pairing mode and select it from the Bluetooth device list again.
Use the Unifying receiver as a fallback
Insert the mouse’s paired Unifying receiver into the computer and select the corresponding M720 channel. This lets you connect a Logitech wireless mouse through its receiver while bypassing Bluetooth. It does not repair the computer’s Bluetooth radio.
If you have a replacement receiver or its pairing was overwritten, get Logi Options+ from the official Logi Options+ download page if needed, choosing the download for your supported operating system. Open Logi Options+, choose to add a device, select the Unifying receiver option, and complete the on-screen pairing instructions. Logitech directs you to Options+ for this workflow because its standalone Unifying Software is unsupported and unmaintained.
For a receiver that still will not connect, remove and reinsert it, then try a different direct USB port instead of a hub or KVM. Move the mouse closer, keep other wireless equipment away, and restart the computer.
If the receiver connection still fails, remove and re-add the mouse in Options+. Try the Unifying connection on another computer to help isolate the failure.
Frequently Asked Questions
Do you need Logi Options+ to pair the M720 over Bluetooth?
Basic Bluetooth pairing uses your operating system’s settings and does not require Options+. If you already have Options+, its add-device Bluetooth option opens those settings so you can complete pairing there.
Can every M720 channel use Bluetooth?
Each of the three M720 channels supports either Bluetooth or Unifying. You can choose any numbered channel for a Bluetooth connection.
Can you recharge the Logitech M720 with a USB cable?
The M720 is not USB-rechargeable. It uses a replaceable AA battery.
What can you change if the mouse disconnects after Windows wakes from sleep?
On Windows 11 adapters that expose power controls, you can prevent Windows from turning off the adapter to save energy. Open Device Manager > Bluetooth, right-click the adapter, and select Properties > Power Management. If that tab is available, uncheck Allow the computer to turn off this device to save power, select OK, and restart. If it is absent, select the taskbar Battery icon and turn off the enabled Energy Saver Mode, then check the connection again.
Why does the mouse pair with a Mac but remain missing from Options+?
Options+ Bluetooth permission affects app detection separately from the operating system’s initial pairing. On current macOS, open System Settings > Privacy & Security > Bluetooth, enable Logi Options+, and select Quit & Reopen. This can address detection problems, particularly when the mouse is not actively connected to that Mac.
What if the mouse connects to a Mac but its buttons or gestures do not work?
For Options+ scrolling, button, gesture, or customization problems after pairing, open System Settings > Privacy & Security > Input Monitoring, enable Logi Options+, and select Quit & Reopen. Also enable Logi Options+ under Device Control and Data Access on macOS 27, or under Accessibility on earlier supported macOS versions.
