Keyboards are essential tools for interacting with our computers, whether you’re typing up important documents, browsing the internet, or gaming. So, it can be incredibly frustrating when your keyboard suddenly stops working. If you’re asking yourself, “Why isn’t my keyboard working?”, you’re not alone. Many users experience this issue, and thankfully, there are several common reasons and straightforward solutions to get you back on track.
This guide will walk you through the most frequent causes of a non-functioning keyboard and provide step-by-step troubleshooting methods to resolve each problem. Whether you have a wired USB keyboard or a wireless Bluetooth model, we’ll help you diagnose and fix the issue, ensuring you can type away without further interruption.
Corrupted or Outdated Keyboard Drivers
One of the most common culprits behind a keyboard malfunction is outdated, corrupted, or missing driver software. Drivers are essential software that allows your operating system to communicate effectively with your keyboard hardware. When these drivers become outdated or corrupted, communication breaks down, and your keyboard may stop responding. This is especially relevant when you’ve recently switched keyboards, as old drivers can sometimes conflict with new hardware.
Keeping your drivers updated is a crucial aspect of maintaining a healthy and smoothly running computer. Up-to-date drivers ensure that all your connected devices, including your keyboard, function optimally. Consider using a driver updater tool to automate this process and ensure you always have the latest versions.
Avast Driver Updater can help simplify driver management by automatically scanning, downloading, and updating drivers to keep your system running smoothly and prevent hardware conflicts.

Motherboard Issues
While less frequent, a faulty motherboard can be a more serious reason for keyboard unresponsiveness. The motherboard is the central hub of your computer, managing communication between all components, including the keyboard. If there’s a problem with the motherboard itself, it can lead to intermittent or complete keyboard failure.
If you suspect a motherboard issue, it’s best to seek professional help. An IT technician can perform diagnostic tests to examine your computer’s internal components and pinpoint the source of the problem. They can then advise on the best course of action, whether it’s a repair or a component replacement.
Physical Damage and Debris
Are only some keys on your keyboard acting up? If so, accidental damage, often due to food crumbs, dust, or liquid spills, is a likely cause. These substances can get lodged under the keys, preventing them from making proper contact and registering keystrokes. Regular computer cleaning, including your keyboard, is vital for preventing debris build-up and ensuring longevity.
Fortunately, there’s often a simple fix for this. For laptops or external keyboards, unplug or turn off your device, carefully turn it upside down, and gently shake it. This can dislodge crumbs and dust trapped beneath the keys.
For spills, use a slightly damp, lint-free cloth or cotton swab with warm water or rubbing alcohol to carefully clean around and between the keys. Avoid pouring liquid directly onto the keyboard.
Wireless Keyboard Battery or Connection Problems
If you’re using a wireless keyboard and it’s stopped working, the most obvious first check is the battery. Wireless keyboards rely on batteries or rechargeable power. Low battery power is a common reason for disconnection or unresponsiveness. This is particularly probable if your wireless mouse is still working correctly while your keyboard is not. To quickly test this, try plugging in a wired keyboard; if it works, then battery issues are likely the culprit.
For rechargeable wireless keyboards, connect it to your computer or power adapter to recharge fully. For battery-operated keyboards, replace the batteries with a fresh set. After ensuring sufficient power, try toggling Bluetooth off and then back on in your computer’s settings. You might need to re-pair your keyboard and computer if they don’t automatically reconnect.
Incorrect USB Port Connection
For USB keyboards, a surprisingly frequent cause of them not working is simply being plugged into the wrong USB port or a malfunctioning port. Sometimes, a particular USB port may not be providing power or data transfer properly.
To troubleshoot, unplug your keyboard and try connecting it to different USB ports on your computer, one at a time, until it works. If you still face issues, try connecting your keyboard to a different computer to confirm if the keyboard cable itself is functioning correctly. This will help isolate whether the problem lies with the keyboard or your computer’s USB ports.
System Updates and Conflicts
Operating system updates are essential for security and performance, but occasionally, they can lead to temporary compatibility issues with peripheral hardware like keyboards and mice. A recent update might have altered settings or introduced a software bug that’s causing your keyboard to become unresponsive. This is less likely to be the cause for built-in laptop keyboards, but more relevant for external keyboards.
While keeping your software updated is generally crucial, you can try to determine if a recent update is the problem by attempting to roll back to a previous system restore point or uninstalling the latest update temporarily. This can help you isolate whether the update is the root cause.
Power Saving Settings Interfering with Keyboard
If you’re using an external keyboard with a laptop and it’s intermittently disconnecting or not working, power-saving features could be the cause. Laptops employ power-saving modes to extend battery life by reducing power consumption to peripherals when they are inactive for a certain period.
These settings can sometimes aggressively disconnect USB devices, including keyboards. Check your power settings and adjust them to prevent peripheral devices from being turned off to save power.
How to Fix a Keyboard That Isn’t Typing
When your keyboard stops typing, it can feel like you’re locked out of your computer. Fortunately, you can often use an on-screen or virtual keyboard as a temporary workaround. Once you’ve enabled the on-screen keyboard, you can restart your device and follow these troubleshooting steps to get your physical keyboard working again.
Here are the steps to troubleshoot and fix a keyboard that’s not working properly:
1. Enable the On-Screen Keyboard
To navigate your computer without a physical keyboard, you can activate the on-screen keyboard using your mouse.
- Open the Windows Start Menu: Use your mouse to click on the Start button.
- Go to Settings: Click on the Settings icon (gear icon).
- Select Ease of Access: In the Settings menu, find and click on Ease of Access.
- Navigate to Keyboard: In the left sidebar, select Keyboard.
- Turn on On-Screen Keyboard: Toggle the switch under “Use the On-Screen Keyboard” to the On position.
Once the on-screen keyboard is active, you can use your mouse to type and navigate your computer to perform the following troubleshooting steps.
2. Restart Your Device
A simple restart can often resolve temporary software glitches that might be causing your keyboard to malfunction. Whether it’s wireless or wired, restarting your keyboard and computer can refresh the connection and system processes.
