Laptop Keyboard Not Working – Complete Troubleshooting Guide (2026)



Introduction

A laptop keyboard is one of the most essential components, but what happens when it suddenly stops working? 😫

This problem can happen for many reasons: hardware damage, driver issues, software conflicts, or even simple settings. Many guides online give vague advice, but in this post, you will get a complete step-by-step solution to fix your laptop keyboard and prevent future problems.

Whether you are using Windows or Mac, this guide has every possible solution covered.

Why Laptop Keyboards Stop Working

Keyboards can stop working for various reasons:

  • Hardware failure – damaged keys, water damage, loose connection

  • Driver issues – outdated or corrupted drivers

  • Software conflicts – third-party apps or updates

  • Settings changes – disabled keyboard or filter keys enabled

  • BIOS or firmware issues – keyboard not recognized at startup

Understanding the cause will help you fix it effectively.

Step 1 – Restart Your Laptop

Many keyboard issues are temporary and can be fixed with a simple restart.

How to Restart

  • Save all your work and close applications

  • Press Restart from the Start menu (Windows) or Apple menu (Mac)

  • After reboot, test the keyboard

Step 2 – Check for External Devices

Sometimes connected peripherals like USB drives or external keyboards interfere with the laptop keyboard.

Steps

  1. Disconnect all external devices (mouse, USB, external keyboard)

  2. Restart the laptop

  3. Test the keyboard

Step 3 – Check Keyboard Settings

Incorrect settings can disable the keyboard.

Windows Settings

  • Go to Control Panel → Ease of Access → Keyboard

  • Ensure Filter Keys is OFF

  • Check Keyboard language/layout is correct

Mac Settings

  • Go to System Preferences → Keyboard → Input Sources

  • Verify correct layout is selected

Step 4 – Update or Reinstall Keyboard Drivers

Drivers control how your keyboard communicates with the operating system. Corrupted or outdated drivers can cause failure.

Windows Steps

  1. Press Windows + X → Device Manager

  2. Expand Keyboards

  3. Right-click your keyboard → Update driver

  4. If problem persists, select Uninstall device → Restart laptop (Windows will reinstall driver automatically)

Mac Steps

  • macOS updates usually handle drivers automatically

  • Go to System Preferences → Software Update and ensure system is up-to-date

Step 5 – Boot Into Safe Mode

Booting in Safe Mode helps identify software conflicts causing keyboard failure.

Windows Safe Mode

  1. Press Shift + Restart → Troubleshoot → Advanced options → Startup Settings → Restart

  2. Select Safe Mode

  3. Test the keyboard

Mac Safe Mode

  1. Shut down your Mac

  2. Power on while holding Shift key

  3. Release when login window appears

  4. Test keyboard

If keyboard works in Safe Mode → problem is software-related.

Step 6 – Check for Hardware Issues

If software fixes don’t work, the problem may be hardware-related.

Steps

  • Inspect for visible damage, debris, or water spills

  • Clean with compressed air or soft brush

  • For laptops with removable keyboards, reseat the connection cable

  • If internal keyboard is damaged, consider replacement

Step 7 – Use External Keyboard (Temporary Fix)

If internal keyboard is not working, an external USB or Bluetooth keyboard can be used while troubleshooting.

  • USB keyboards work immediately

  • Bluetooth keyboards require pairing

  • Useful to test whether issue is hardware or software

Step 8 – Reset BIOS or Firmware

Sometimes the keyboard is disabled at BIOS level.

Steps

  1. Restart laptop → Enter BIOS (usually F2, F10, or Delete key)

  2. Check keyboard settings → ensure enabled

  3. Reset BIOS to default settings

  4. Save and exit → test keyboard

Step 9 – Check for Malware or Software Conflicts

Certain malware or apps can block keyboard input.

  • Run full antivirus scan

  • Use Malwarebytes or other trusted software

  • Disable unnecessary startup apps

Step 10 – Reinstall Operating System (Last Resort)

If all else fails, a clean OS reinstall can resolve software-related issues.

  • Backup all important data

  • Use official Windows/macOS reinstall tools

  • After reinstall, test keyboard before restoring all files

Bonus Tips to Prevent Keyboard Issues

  • Avoid eating/drinking near laptop

  • Keep keyboard clean and dust-free

  • Update system and drivers regularly

  • Use keyboard protector if needed

FAQs (Frequently Asked Questions)

Q1: My keyboard works in BIOS but not in Windows. Why?

It usually indicates a driver or software conflict. Try Safe Mode or reinstall drivers.

Q2: Can water damage be repaired at home?

Minor spills can sometimes be cleaned, but serious water damage requires professional repair or replacement.

Q3: Why do some keys work but others don’t?

Possible hardware fault or physical debris under keys. Cleaning or replacement may be needed.
