Experiencing your computer suddenly typing in all caps can be both confusing and frustrating. This issue can occur in both Windows and Mac systems, across desktops and laptops. Fortunately, resolving this is usually straightforward. In this blog, we will explore various solutions to address the issue of your computer typing in all caps for both Windows and Mac users.

For Windows Users

1. Check the Caps Lock Key

  • Initial Step: The most obvious solution is to check if the Caps Lock key on your keyboard is on. Simply press the Caps Lock key and see if that resolves the issue.

2. Sticky Keys Feature

  • Understanding Sticky Keys: Sticky Keys is an accessibility feature in Windows that allows modifier keys to remain active even after they've been released.
  • Disable Sticky Keys: Press the Shift key five times quickly to toggle Sticky Keys on or off. Alternatively, go to Settings > Ease of Access > Keyboard and turn off Sticky Keys.

3. Keyboard Driver Issues

  • Update Drivers: Outdated or corrupted keyboard drivers can cause various typing issues. Go to Device Manager, find your keyboard, right-click and select "Update driver."
  • Reinstall Drivers: If updating doesn't work, you might need to reinstall the driver. Right-click on the keyboard in Device Manager and choose "Uninstall device." Then restart your computer.

4. Check for Malware

  • Run a Malware Scan: Sometimes, malware can interfere with keyboard functionality. Use your antivirus program to run a comprehensive system scan.

5. External Keyboard Check (for laptops)

  • Testing with an External Keyboard: If you're using a laptop, try connecting an external keyboard. If the problem doesn't occur with the external keyboard, the issue might be with your laptop's built-in keyboard.

For Mac Users

1. Caps Lock Key

  • Basic Check: As with Windows, first check if the Caps Lock key is engaged.

2. Keyboard Preferences

  • Modifier Keys Configuration: Go to Apple Menu > System Preferences > Keyboard. Click on "Modifier Keys" and ensure Caps Lock isn't set to perform another action.

3. PRAM and SMC Reset

  • Reset PRAM (Parameter RAM): Restart your Mac and immediately press Option, Command, P, and R.
  • Reset SMC (System Management Controller): The process varies depending on the Mac model, but generally involves shutting down your Mac and using a key combination during startup.

4. Check for macOS Updates

  • Update macOS: Ensure that your Mac is running the latest version of macOS. Go to Apple Menu > System Preferences > Software Update.

5. Create a New User Account

  • Test with a New Account: Sometimes, the issue could be related to your user account settings. Try creating a new account and check if the issue persists there.

General Troubleshooting Tips

  • Restart Your Computer: Regardless of the OS, a simple restart can sometimes resolve unexpected issues.
  • Clean Your Keyboard: Dust or debris under the keys can sometimes cause typing problems. Clean your keyboard carefully.
  • Seek Professional Help: If none of these solutions work, it's best to consult with a professional technician.


In most cases, a computer typing in all caps can be resolved through the solutions mentioned above. Whether you're using Windows or Mac, checking the Caps Lock key and keyboard settings is a good starting point. For persistent problems, updating drivers or the OS, or even resetting specific settings can be effective. If you've tried these solutions without success, it may indicate a hardware issue, especially in laptops, and professional assistance is recommended. Remember, regular maintenance and updates can prevent many such issues.
