Why has my keyboard stopped working?
The reasons your computer or laptop keyboard might suddenly stop working can range from software issues, such as buggy updates or corrupted drivers, to physical problems, like a damaged motherboard or keyboard. For wireless keyboards, the issue could be as simple as a drained battery.
Depleted battery
Like any other wireless device, wireless keyboards will eventually run out of battery. To check if it’s a battery issue, try connecting the keyboard to your computer with a cable to charge it. If it works, then it’s likely a battery problem. For keyboards with replaceable batteries, simply insert fresh ones.
Bluetooth issues
In some cases, your wireless keyboard may not automatically reconnect with your Mac or PC due to Bluetooth issues. Try turning Bluetooth off and on again, and check for reconnection.
Faulty USB port or cable
USB keyboards may not work if the USB port is incompatible or faulty. To check, unplug the keyboard and try connecting it to other USB ports on your device. If the keyboard works in a different port, the issue was likely with the original USB port.
It’s also possible the keyboard cable is damaged. To test this, try connecting the keyboard to another device. If it doesn’t work there, the problem may be with the cable.
Physical damage
Over time, your keyboard may experience natural wear and tear. Which keys are affected often depends on usage patterns, but common issues often involve the space bar, shift key, or any other keys you use more than others. In addition to not producing a response, “dead keys” can become stuck, loose, uneven, or even produce the wrong character.
Sometimes, keyboards can be damaged by crumbs or liquid that fall between the keys. This can often be resolved by holding the keyboard upside down and gently shaking it to dislodge debris. For more stubborn debris, use a can of compressed air. If a liquid spill occurs, gently clean between the keys with a cotton swab or a thin cloth.
Physically cleaning your computer every so often is recommended so that issues such as damaged keyboards don’t appear in the first place.
Power saving features
If an external keyboard suddenly stops working, it might be due to your device’s power-saving settings. These features help save your battery life by performing actions like dimming the screen. They may also disconnect peripheral devices, such as wireless keyboards, if they remain inactive for too long.
Missing or corrupted drivers
A driver is a set of software files that allow hardware to communicate with a computer’s operating system, letting the hardware function. They are needed for wireless keyboards, although some specialist USB keyboards also require them. For your computer to function effectively, all its drivers — graphics drivers, sound drivers, or any other kind — must work.
Drivers can become outdated or even be missing altogether. This is a common problem when switching keyboards, as the driver for your old keyboard may still be in place, potentially disabling your new keyboard.
The easiest way to check if drivers are up to date is with automatic software, such as AVG Driver Updater. Not only will this help keep your keyboard running optimally, but it will also streamline driver updates for other devices, like graphics cards and headphones. Get dedicated driver updater software to automatically scan for the latest drivers so all your devices remain optimized.
Incompatible updates
System updates are important for maintaining your computer’s performance and security, but they can occasionally cause issues. Sometimes, these updates disrupt existing settings or introduce bugs that can make your keyboard unresponsive. If your keyboard stopped working right after an update, this is likely the cause.
Faulty motherboard
Over time, a computer's motherboard may become faulty. A motherboard is a computer's main circuit board; it functions like its brain, connecting the rest of its internal hardware. Since the motherboard handles numerous functions, including the keyboard, a malfunctioning motherboard can cause partial or complete keyboard failure.
A damaged motherboard may also cause issues in other areas of your computer. If your PC is experiencing symptoms such as random freezing or shutdowns, overheating, or a failure to boot up, the motherboard may be responsible. Because of the complexity of motherboard issues, it’s best to consult an IT professional if you suspect this might be the problem. They can examine your computer in detail, diagnose the issue, and hopefully repair it.
How do I fix my keyboard not working?
You can fix a keyboard that won’t type by restarting your device, updating drivers, and cleaning your keyboard, among other solutions.
Turn on the on-screen keyboard
Before you begin, set up an on-screen keyboard so you’ll still have access to typing while troubleshooting issues with your physical keyboard.
Both Windows and Mac have an on-screen keyboard function to help you troubleshoot these exact issues.

Restart your keyboard and computer
Now that you have your on-screen keyboard set up, the next step to troubleshoot your keyboard issue is to restart your computer.
If this doesn’t resolve the problem, try resetting your keyboard. For wired keyboards, unplug the keyboard from your computer; for wireless ones, turn it off. After a few seconds, press and hold the Esc key as you reconnect the keyboard or switch it back on. Keep holding the Esc key for five seconds, then release it.
If the reset is successful, the keyboard light should start flashing. At this point, check if your keyboard is functioning again.
You can also reset your keyboard directly from your computer.
How to reset your keyboard on a Windows device

Clean your keyboard
Cleaning dirt, dust, and spills from your keyboard can help keep it functioning properly. Follow the methods below to effectively clean your keyboard.
Before you begin, ensure that your computer is unplugged and powered off. If you have an external USB keyboard, disconnect it from the computer.
-
Turn the keyboard upside down and give it a gentle shake to remove loose debris.
-
Use a soft brush to dislodge any additional particles.
-
For dust removal, use a can of compressed air. Hold the can at least six inches away from the keyboard to avoid accidental damage.
-
If needed, use a mini vacuum cleaner to remove any remaining debris.
-
Finish by polishing the keyboard with a lint-free cloth.
