Logitech MX Master 3 Not Working, How to Fix?

Fix 1: Ensure your Mouse is Turned On and Connected

The most probable explanation as to why your mouse might have suddenly stopped working could be because it isn’t turned on. Check the power switch on your mouse and ensure it’s set to the on position. Additionally, since the MX Master 3 has 3 different profiles to connect to different devices, make sure you have selected the correct channel for the device you’re trying to use the mouse on.

Fix 2: Reconnect your Mouse

A weak Bluetooth connection between your mouse and your device could also be causing you trouble while using the mouse. Simple disconnect your mouse on your computer or laptop and pair it again.

Fix 3: Use a different Cable

One of the reasons why you might not have been able to use your mouse could be because of a faulty charging cable. Try using another cable to see any positive results. If the problem still persists, try charging your mouse using a different device or adapter.

Fix 4: Install the Logitech G Hub Software

While most Logitech products benefit from the customization power that comes with the G Hub software, it also sometimes acts as a downside since you need the program for some of the most basic things like updating your device’s firmware. If you don’t already have the Logitech G Hub software installed on your computer, head to their official website and grab the download file. Install the program, reboot your computer, and see if that fixes your issue.

Fix 5: Update your Mouse’s Firmware

The mid and high-tier products from Logitech’s catalog receive frequent firmware updates that bring quality of life improvements and additional features. The updates also fix several bugs that have been reported in the past. Launch the Logitech G Hub software, click on your MX Master 3 mouse, and check to see if your device has any firmware updates available. If there is one, we recommend you install it since the update might fix any bugs that could have been preventing you from properly using your mouse.

Fix 6: Repair/Reinstall Logitech G Hub

Another huge reason that might cause the infamous MX Master 3 not working issue is a faulty app install of the G Hub software. This is quite a common occurrence and happens when you shut your computer down right when the app was updating. Luckily, the Logitech G Hub software comes with a nifty little repair tool that scans all the installation files, finds the faulty ones, and redownloads them to fix the malfunctioning app. Additionally, you can simply uninstall and reinstall the G Hub software for an even cleaner installation.

Fix 7: Contact Logitech Support

If you’ve followed all the fixes provided above and still haven’t had luck with your mouse, then this could very well be a hardware issue that cannot be fixed by you. You can try contacting Logitech support and send in your mouse for a repair or replacement if you still have the bill.
