Keyboard & Mouse Not Connecting? Quick Fixes (2025 Guide)

Keyboard & Mouse Quick Fixes

Few things are more frustrating than sitting down to work and finding your keyboard and mouse not connecting. Whether you use a wireless combo like the Logitech MK270 or standalone devices like the M185 or M240 Silent Bluetooth, connectivity issues can usually be solved with a few simple steps. This guide walks you through quick troubleshooting fixes for 2025.

Step 1 – Check the Power and Batteries

Ensure the devices are powered on (look for a switch on the bottom of the mouse or keyboard).
Replace old batteries with fresh ones—many issues come down to weak battery power.
On rechargeable models, confirm the device is charged via USB-C or micro-USB cable.

Step 2 – Check the USB Receiver or Bluetooth Pairing

For 2.4GHz USB receivers (e.g., M185, MK270): Reinsert the dongle into another USB port. Avoid hubs—plug directly into the computer.
For Bluetooth devices (e.g., M240): Ensure Bluetooth is turned on, remove the device from your system, and re-pair it from scratch.
Try moving closer to the computer to rule out signal interference.

Step 3 – Update Drivers and Software

Check Windows Update or macOS Software Update for input driver updates.
Install or update Logitech Options/Logi+ software if supported by your model.
On Chromebooks, ensure your ChromeOS version is current.

Step 4 – Reset the Devices

Turn both devices off and back on.
On combos like the MK270, power-cycle both the keyboard and mouse.
Hold pairing buttons (on Bluetooth models) for a few seconds to reset connection.

Step 5 – Advanced Troubleshooting

Check for radio interference from other 2.4GHz devices (Wi-Fi routers, cordless phones).
Try a different computer to confirm the issue is with the device, not the system.
If nothing works, contact Logitech support for device replacement under warranty.

Device-Specific Tips

Logitech MK270 Combo – If neither device connects, the dongle may be faulty. Try pairing with another Logitech receiver if you own one.
Logitech M185 – If unresponsive, swap batteries and replug the receiver directly into the PC.
Logitech M240 Silent Bluetooth – Delete the pairing in your OS Bluetooth settings and re-add the device.

When to Replace Your Keyboard or Mouse

If you’ve tried all the steps and your devices still fail, it may be time for a replacement. Logitech budget models like the M185 often last years, but eventually wear out. Investing in a fresh set like the MK270 combo or the quieter M240 Bluetooth mouse can save hours of frustration.
