1. Preliminary Checks: The First Line of Defense

Before diving into more complex solutions, let’s cover the basics. Often, the simplest solutions are the most effective.

1. 1 Check the Obvious: Physical Connections

Is your keyboard properly connected? This seems basic, but it’s often the culprit.

Wired Keyboards: Ensure the USB cable is securely plugged into both the keyboard and the computer. Try a different USB port. Some ports might be faulty or have power issues.
Wireless Keyboards: Verify the keyboard is powered on. Check the battery level. Replace batteries if needed or fully charge the keyboard.

1. 2 Rule Out the Blindingly Obvious: Is it Really the Keyboard?

Confirm the problem is with the keyboard, not the computer.

Restart Your Computer: A simple restart can resolve temporary software glitches that might be interfering with keyboard function.
Test on Another Computer: Connect your keyboard to another computer to see if it works there. If it doesn’t, the keyboard itself is likely the issue.
Try a Different Keyboard: Connect a different keyboard to your computer. If the new keyboard works, the original keyboard is faulty.

1. 3 Check for Physical Obstructions: The Crumb Conspiracy

Debris under the keys can prevent them from functioning correctly.

Turn the Keyboard Upside Down: Gently shake the keyboard to dislodge any loose debris.
Use Compressed Air: Use a can of compressed air to blow out any dust or crumbs trapped beneath the keys. Hold the can at an angle to avoid spraying liquid propellant.
Clean Sticky Keys: Use a cotton swab dampened with isopropyl alcohol to gently clean around sticky keys.

2. Diving Deeper: Software and Driver Issues

If the physical checks don’t solve the problem, the issue may be related to software or drivers.

2. 1 The Driver Dilemma: Corrupted or Outdated Drivers

Drivers are essential software that allows your computer to communicate with the keyboard. Corrupted, outdated, or missing drivers can cause keyboard malfunctions.

Access Device Manager:
- Windows: Press Windows Key + X and select “Device Manager.”
- Mac: Access via “System Information” (search in Spotlight), then navigate to “Hardware” and “USB” or “Bluetooth” depending on the keyboard type.
Locate Keyboards: Expand the “Keyboards” category.
Check for Errors: Look for a yellow exclamation mark next to your keyboard device, indicating a problem.
Update Drivers:
- Automatic Update: Right-click on the keyboard device and select “Update driver.” Choose “Search automatically for drivers.”
- Manual Update: If the automatic update doesn’t work, visit the keyboard manufacturer’s website and download the latest driver for your operating system. Install the driver manually.
Roll Back Drivers: If the keyboard stopped working after a recent driver update, try rolling back to the previous driver version. In Device Manager, right-click on the keyboard device, select “Properties,” go to the “Driver” tab, and click “Roll Back Driver.”

2. 2 Filter Keys and Sticky Keys: Accessibility Features Gone Wrong

These accessibility features can sometimes interfere with normal keyboard function.

Access Ease of Access Settings:
- Windows: Search for “Ease of Access keyboard settings” in the Windows search bar.
Disable Filter Keys: Ensure “Turn on Filter Keys” is unchecked.
Disable Sticky Keys: Ensure “Turn on Sticky Keys” is unchecked.

2. 3 On-Screen Keyboard: A Temporary Solution and Diagnostic Tool

The on-screen keyboard can serve as a temporary workaround and help diagnose the problem.

Enable On-Screen Keyboard:
- Windows: Search for “On-Screen Keyboard” in the Windows search bar and launch the application.
Test Functionality: If the on-screen keyboard works, the issue is likely with the physical keyboard or its drivers.
If the on-screen keyboard doesn’t work, the issue is more likely to be with your operating system.

2. 4 Keyboard Layout: Accidental Language Changes

Sometimes, the keyboard layout can be accidentally changed, causing keys to produce unexpected characters.

Check Language Settings:
- Windows: Search for “Language settings” in the Windows search bar.
- Mac: Go to “System Preferences” > “Keyboard” > “Input Sources.”
Verify Correct Layout: Ensure the correct keyboard layout is selected.
Add or Remove Layouts: Add or remove keyboard layouts as needed.

2. 5 BIOS Settings: A Rare but Possible Culprit

In rare cases, BIOS settings can affect keyboard functionality, especially during startup.

Access BIOS Settings: Restart your computer and press the key indicated on the screen to enter BIOS setup (usually Del, F2, F12, or Esc).
Check Keyboard Settings: Look for keyboard-related settings. Ensure the keyboard is enabled.
Restore Default Settings: If you’re unsure, try restoring the BIOS to its default settings. Be cautious when making changes to BIOS settings.

3. Wireless Keyboard Woes: Bluetooth and Connectivity

Wireless keyboards add another layer of complexity.

3. 1 Bluetooth Pairing: Re-establish the Connection

Bluetooth keyboards need to be properly paired with the computer.

Ensure Bluetooth is Enabled:
- Windows: Search for “Bluetooth settings” in the Windows search bar.
- Mac: Go to “System Preferences” > “Bluetooth.”
Put Keyboard in Pairing Mode: Refer to your keyboard’s manual for instructions on how to put it in pairing mode (usually a button press or combination).
Pair the Keyboard: In the Bluetooth settings, select your keyboard from the list of available devices and follow the on-screen instructions to pair it.
Remove and Re-pair: If the keyboard is already paired but not working, try removing it from the list of devices and re-pairing it.

3. 2 Interference: A Wireless Juggernaut

Wireless signals can be affected by interference from other devices.

Minimize Interference: Keep the keyboard close to the computer. Remove any potential sources of interference, such as other Bluetooth devices, microwaves, or cordless phones.
Try a Different Location: Sometimes, simply moving the keyboard or the computer to a different location can improve the signal.

3. 3 Power Management: The Energy Saver

Power management settings can sometimes disable Bluetooth devices to save battery.

Disable Power Saving for Bluetooth:
- Windows: In Device Manager, locate your Bluetooth adapter, right-click, select “Properties,” go to the “Power Management” tab, and uncheck “Allow the computer to turn off this device to save power.”

4. Specific Key Issues: Troubleshooting Individual Keys

Sometimes, the problem is limited to a few specific keys.

4. 1 Stuck Keys: The Physical Battle

Physical obstructions are often the cause of stuck keys.

Gentle Manipulation: Gently try to wiggle the key to see if you can free it.
Remove Keycap (Carefully): Use a keycap puller or a small, flat screwdriver to carefully remove the keycap. Clean the area underneath with compressed air or a cotton swab.

4. 2 Ghosting: The Multiple Key Conundrum

Ghosting occurs when pressing multiple keys simultaneously results in some keys not registering. This is often a limitation of the keyboard’s design.

Check Keyboard Specifications: Some keyboards have limitations on the number of keys that can be pressed simultaneously. Check the keyboard’s specifications to see if it supports the key combinations you’re trying to use.
Try Different Key Combinations: If possible, try using different key combinations that don’t involve the keys that are ghosting.
Consider a Gaming Keyboard: Gaming keyboards often have anti-ghosting technology that allows for more simultaneous key presses.

5. Advanced Troubleshooting: When All Else Fails

If you’ve tried all the basic troubleshooting steps and your keyboard is still not working, it’s time to move on to more advanced solutions.

5. 1 System Restore: Turning Back Time

System Restore can revert your computer to a previous state, potentially undoing any software changes that caused the keyboard problem.

Access System Restore:
- Windows: Search for “Create a restore point” in the Windows search bar and click “System Restore.”
Choose a Restore Point: Select a restore point from before the keyboard problem started.
Follow On-Screen Instructions: Follow the on-screen instructions to complete the system restore process. Note that this will revert system files and installed programs to the state they were in at the time of the restore point.

5. 2 Check for Malware: The Unseen Enemy
