The basic steps to pair your mouse
To connect a Logitech Bluetooth mouse, turn on the mouse, hold down the pairing button for three seconds until the light blinks, then go to your computer's Bluetooth settings and select the mouse from the list. The whole process takes about two minutes and works the same way on Windows, Mac, and Linux.
The pairing button is usually on the bottom or side of the mouse — check your specific model's manual or the Logitech website to find exactly where. Once the light starts blinking, your computer should detect it within 10 to 15 seconds. If it does not appear in your Bluetooth list, try holding the button for five seconds instead of three, or move the mouse closer to your computer.
After you select the mouse from the list, your computer will pair with it automatically. You do not need to enter a code or do anything else. The mouse will remember your computer the next time you turn it on, so you only pair it once.
Key Takeaways
- The pairing button is usually on the bottom or side of the mouse and needs to be held for three to five seconds until the light blinks.
- Your computer's Bluetooth settings will show the mouse in a list once it is in pairing mode, and you select it to complete the connection.
- Pairing happens only once — after that, the mouse connects automatically when you turn it on and your computer's Bluetooth is on.
- If the mouse does not appear in your Bluetooth list, move it closer to your computer or try holding the pairing button longer.
Where to find the pairing button on your mouse
Most Logitech Bluetooth mice have the pairing button on the underside, near the battery compartment or the power switch. Some models put it on the side instead. The button is usually small and recessed so you do not press it by accident.
If you cannot find it, look for a button labeled with a Bluetooth symbol (two triangles pointing up) or the word "Connect". On some older Logitech models, the pairing button might be labeled "Pairing" or have a small icon that looks like a wireless signal. Your mouse's manual or the Logitech support page for your specific model will show you exactly where it is.
How to turn on Bluetooth on your computer
On Windows 10 or 11, click the Start button, type "Bluetooth settings" into the search box, and open the Bluetooth & devices page. Toggle Bluetooth on if it is not already on, then click "Add device" and select "Bluetooth" from the menu that appears.
On a Mac, click the Apple menu in the top left, go to System Settings, then click Bluetooth in the sidebar. Make sure Bluetooth is turned on. Your mouse will appear in the list once it is in pairing mode.
On Linux, the steps vary by which desktop environment you use, but most have a Bluetooth icon in the system tray (usually the top right corner). Click it, select "Add a new device" or similar, and wait for your mouse to appear in the list.
What to do if your mouse does not appear in the Bluetooth list
If you do not see your mouse after holding the pairing button, try these steps in order. First, move the mouse within three feet of your computer — Bluetooth has a short range when pairing. Second, make sure your computer's Bluetooth is actually on by checking the settings again. Third, restart your computer's Bluetooth by turning it off and back on in settings.
If the mouse still does not show up, try holding the pairing button for five to ten seconds instead of three. Some Logitech models need a longer press. You can also try removing the batteries from the mouse for 10 seconds, putting them back in, and then pressing the pairing button again. This resets the mouse's Bluetooth connection.
If none of that works, check whether your computer actually has Bluetooth. Older desktops sometimes do not have it built in. You can buy a small USB Bluetooth adapter (sometimes called a Bluetooth dongle) for $10 to $20 that plugs into a USB port and adds Bluetooth to any computer.
How to know if the pairing worked
Once you select the mouse in your Bluetooth settings, it should say "Connected" or "Paired" next to the mouse's name. The light on the mouse will stop blinking and either turn solid or turn off completely, depending on your model. Move the mouse around — the cursor on your screen should move with it.
If the cursor does not move, the pairing did not complete. Go back to your Bluetooth settings and try selecting the mouse again. If it says "Connected" but the cursor still does not move, restart your computer and try again.
Reconnecting your mouse after turning it off
Once your mouse is paired, you do not need to pair it again. The next time you turn on the mouse, it will automatically connect to your computer if Bluetooth is on. This usually takes five to ten seconds.
If your mouse does not reconnect automatically, check that Bluetooth is turned on in your computer's settings. If it is on but the mouse still does not connect, try turning the mouse off and back on. If that does not work, you can manually select it from your Bluetooth settings again — it will already be in the list, so you just click it once.
Connecting the same mouse to multiple computers
A Logitech Bluetooth mouse can pair with multiple computers, but it can only connect to one at a time. To switch the mouse to a different computer, turn off Bluetooth on the first computer, then turn on Bluetooth on the second computer and select the mouse from the list. The mouse will remember both computers.
Some Logitech mice have multiple pairing buttons or a button that cycles through paired devices. Check your manual to see if yours does. If it does, you can press that button to switch between computers without going into settings each time.
Frequently Asked Questions
Why does my mouse keep disconnecting?
Bluetooth disconnections usually happen because something is blocking the signal between your mouse and computer. Move the mouse closer, remove any metal objects between them, and check whether other wireless devices nearby (like a microwave or cordless phone) are interfering. If disconnections keep happening, try replacing the batteries in your mouse — low batteries are a common cause.
Do I need to install software to use a Logitech Bluetooth mouse?
No. Bluetooth mice work without any software — your computer's built-in Bluetooth driver handles the connection. Logitech makes optional software called Logi Options+ that lets you customize buttons and adjust sensitivity, but it is not required to use the mouse.
Can I use a Logitech Bluetooth mouse with a tablet or phone?
Yes. The pairing process is the same on tablets and phones — go to Bluetooth settings, put the mouse in pairing mode, and select it from the list. Not all apps support mouse input on phones, but most tablets work fine with a Bluetooth mouse.
What if I forgot which computer I paired my mouse with?
Put the mouse in pairing mode again by holding the pairing button for three to five seconds. Your computer will detect it and show it in the Bluetooth list. Select it to pair again — this will not unpair it from other computers, it will just add a new pairing.
How far away can my mouse be from my computer?
Bluetooth typically works within 30 feet in open space, but walls and other obstacles reduce that range. For a mouse, you usually want to keep it within 10 feet of your computer for a reliable connection. If your mouse keeps disconnecting, moving it closer is the first thing to try.
