Fix: Battlefield 2042 Keyboard / Mouse Not Working or Lagging

It basically ruins the gameplay experience for the PC players due to in-game mouse or keyboard lag apart from not working issues. Now, without wasting any more time, let’s jump into it.

1. Reconnect Mouse and Keyboard

First of all, you should try disconnecting and reconnecting the mouse as well as the keyboard on the PC to ensure there is no connectivity issue at all. Sometimes a poor or loose USB connectivity to the port may cause such issues.

2. Update Mouse and Keyboard Driver

Make sure to update the mouse and keyboard driver on the PC because an outdated or missing driver may trigger several issues with the peripheral connectivity as well as operations whatsoever. To do that:

• Right-click on the Start Menu to open up the Quick Access Menu.
• Click on Device Manager from the list to open the interface.
• Now, you’ll need to double-click on Keyboards to expand it.
• Then right-click on the active keyboard device that you’re using.
• Next, click on Update driver > Choose Search automatically for drivers.
• The system will automatically check for the available update.

You’ll have to follow the same steps again but for the Mice and other pointing devices adapter this time. While the rest of the steps will be the same.

3. Check for the Mouse and Keyboard Software Update

These days most keyboard and mouse manufacturers do offer dedicated software where the connected mouse or keyboard device can be configured. Some popular brands like Logitech, Dell, SteelSeries, Cooler Master, etc manufacturers do offer peripheral software on the PC. To do so, just head over to the respective website of the device and download the latest software on the PC depending on your specific model number.
