Are you experiencing Bluetooth keyboard or mouse disconnection problems on your Dell laptop or desktop running Windows 11? Does your wireless keyboard stop responding, randomly disconnect, experience input lag, or fail to reconnect after sleep mode?

These problems can occur due to outdated Bluetooth drivers, Windows power management settings, wireless interference, weak batteries, or device pairing issues.

5 Troubleshooting Steps to Fix Bluetooth Connection Problems

1. Check Bluetooth Power Management

Open Device Manager → Bluetooth → Right-click your Bluetooth adapter → Properties → Power Management.

If available, uncheck Allow the computer to turn off this device to save power and restart your PC.

2. Update Bluetooth Drivers

5. Reduce Wireless Interference

• Check or replace your keyboard and mouse batteries.

• Keep your Bluetooth devices closer to your computer.

• Move wireless receivers away from USB 3.0 devices.

• Check for nearby wireless interference.

• Restart your computer after applying changes.
