Keyboards and mice are essential computer peripherals, whether you’re working, gaming, or just browsing the web. But what happens when your keyboard stops responding or your mouse starts lagging? Instead of rushing to buy a new one, there are several ways to fix a broken keyboard or mouse without replacing it.
In this guide, we’ll explore common keyboard and mouse problems, troubleshooting steps, and maintenance tips to extend their lifespan.
Common Keyboard Problems and Fixes
1. Unresponsive Keys
If your keyboard is not typing, some keys are not working, or the entire keyboard is unresponsive, try these solutions:
- Check the connection – For wired keyboards, ensure the USB or PS/2 cable is properly plugged in. Try using a different USB port. For wireless keyboards, replace the batteries or check the Bluetooth connection.
- Restart your computer – Sometimes, a simple reboot can fix unresponsive keys.
- Check for debris – Dust and dirt can accumulate under the keys, blocking their movement. Use compressed air or a soft brush to clean between the keys.
- Try an external keyboard – If an external keyboard works fine, the issue may be with your built-in keyboard or software settings.
2. Sticky or Jammed Keys
Sticky or jammed keys can make typing difficult. To fix this:
- Turn off the keyboard and clean it – Remove keycaps (for mechanical keyboards) and clean underneath with a damp cloth or isopropyl alcohol.
- Use compressed air – Blow out dust and debris trapped under the keys.
- Check for spills – If liquid was spilled, turn off the keyboard immediately, remove any power source, and clean it thoroughly.
3. Keyboard Not Connecting
If your keyboard is not detected by your computer:
- For wired keyboards, try a different USB port or cable.
- For wireless keyboards, ensure Bluetooth is enabled, replace the batteries, or re-pair the device.
- Check device drivers – Update or reinstall the keyboard drivers through the Device Manager.
4. Keys Typing the Wrong Characters
If pressing one key results in the wrong character appearing on the screen:
- Check keyboard language settings – Go to your computer’s language settings and ensure the correct keyboard layout is selected.
- Disable Sticky Keys or Filter Keys – These accessibility features can interfere with typing.
Common Mouse Problems and Fixes
1. Cursor Not Moving or Lagging
If your mouse cursor is not moving or is slow to respond:
- Clean the sensor – Dust or debris can block the optical sensor. Use a cotton swab and rubbing alcohol to clean it.
- Use a proper surface – Optical and laser mice work best on smooth, non-reflective surfaces. Try a mouse pad for better accuracy.
- Check USB or wireless connection – Unplug and reinsert the USB receiver, or replace the batteries if using a wireless mouse.
2. Mouse Buttons Not Clicking Properly
If the left or right-click buttons are not responding:
- Check for dirt buildup – Dirt and grime can get stuck under the buttons. Use compressed air or a small brush to clean around them.
- Replace worn-out switches – If the click mechanism is faulty, consider replacing the internal switches (this requires technical skill).
3. Wireless Mouse Not Working
If your wireless mouse isn’t responding:
- Replace the batteries – Weak or dead batteries can cause connectivity issues.
- Reconnect the mouse – Unpair and re-pair the mouse via Bluetooth or the wireless USB dongle.
- Check for interference – Other wireless devices may cause interference. Try moving the mouse closer to the receiver.
4. Scroll Wheel Issues
If the scroll wheel isn’t working smoothly:
- Clean the wheel – Dust and lint can build up inside. Use compressed air to clean around the wheel.
- Check software settings – Adjust scroll speed settings in your operating system’s mouse settings.
Software and Driver Fixes
Sometimes, the issue isn’t hardware-related but instead caused by outdated or corrupted drivers. Here’s how to fix software-related problems:
- Update drivers – Go to Device Manager, find your keyboard or mouse, and update the drivers.
- Uninstall and reinstall the device – Removing the device from Device Manager and restarting your computer can reset the connection.
- Check for software conflicts – Some third-party programs can interfere with mouse or keyboard functions. Try running your computer in Safe Mode to see if the issue persists.
Preventive Maintenance Tips
To avoid future problems and extend the life of your keyboard and mouse, follow these maintenance tips:
- Regular cleaning – Dust and debris can accumulate over time. Clean your peripherals weekly using compressed air or a microfiber cloth.
- Use protective covers – Keyboard covers and mouse pads help protect against spills and dirt.
- Avoid eating and drinking near your keyboard – Food crumbs and liquid spills are common causes of sticky keys.
- Store devices properly – When not in use, keep your keyboard and mouse in a clean, dry place.
Conclusion
Fixing a broken keyboard or mouse doesn’t always mean buying a new one. With the right troubleshooting steps, you can resolve common hardware and software issues and extend the life of your peripherals. From cleaning sticky keys to updating drivers, these simple fixes can save you time and money.
