Although it is often overlooked, taking care of the keyboard is important when maintaining a computer device. A clean and well-functioning keyboard supports user productivity and contributes to health.
A dirty keyboard can be a breeding ground for bacteria and germs, leading to health problems such as infections or allergies. Additionally, a keyboard that doesn’t work properly can disrupt workflows, create frustration, and reduce typing efficiency.
The impact of a poorly maintained keyboard is huge. When the keys on the keyboard start to stick or become unresponsive, users often have to spend time fixing or even replacing them.


Common Causes of Keyboard Not Working
A variety of things can cause a keyboard that doesn’t work properly. Here are some common causes that you need to know to identify and appropriately address the problem:
Connection Issues (USB or Bluetooth Unstable)
For wired keyboards, a loose USB connection or a faulty port can make the keyboard undetectable by the computer.
Bluetooth signal interference or a weak battery is often the main culprit on wireless keyboards.
Incorrect software settings, such as uninstalled or outdated drivers, can also cause the keyboard to become unresponsive.
Electronic Damage to the Keyboard
The keyboard has electronic components that transmit signals when the keys are pressed. If there is damage to these components, such as broken circuits or worn keys, the keyboard may not be working properly.
The age of the device also affects its performance. The older the keyboard, the more likely it is to have internal damage.
Dirt Buildup Between Buttons
Keyboards that are not cleaned regularly tend to collect dust, food crumbs, or other debris.
This buildup can interfere with the button mechanism, making it feel sticky or even not able to be pressed at all.
Additionally, moisture from liquid spills can damage the electronic components under the buttons, exacerbating the problem.
Solutions to the Keyboard Not Responding Issue
Facing a keyboard not working issue can be confusing, but many of these issues can be solved with easy steps. Here are some guidelines that can help you fix the problem:
Step 1: Check the Keyboard Connection
Check Physical Connection
Make sure the keyboard cable (for wired ones) is properly connected to the USB port. If necessary, try connecting the keyboard to a different USB port to make sure the previous port is not problematic.
Wireless Keyboard
For wireless keyboards, replace the batteries with new ones. A low battery can make the keyboard not work.
Test on Other Devices
If your keyboard still doesn’t work, try connecting it to another device (like another computer). This helps to know if the problem is with your keyboard or computer.
Step 2: Restart and Update Settings
Restart the Computer
Turn off the computer completely, wait a few seconds, and then turn it back on. Restarting can often resolve software issues that interfere with the keyboard’s functionality.
Check Device Drivers
Make sure your keyboard drivers are installed correctly and updated. To check this, go to the Device Manager menu, search for the keyboard, and update the driver if there is a new one.
Reset Bluetooth Connection
For wireless keyboards that use Bluetooth, disconnect first, then reconnect. This ensures the connection works properly.
How to Clean the Keyboard Properly
Keeping your keyboard clean is essential to ensure it stays performing well and takes care of your health. Here are simple steps to clean the keyboard thoroughly:
Step 1: Clean the Dust
Flip the Keyboard
Lift the keyboard and turn it down. Tap gently to let the dust and debris trapped between the buttons escape.
Use a Small Vacuum Cleaner
To clean deeper dirt, use a vacuum cleaner with a small nozzle. Select a low-power setting so as not to damage the buttons.
Alternatives to Cleaning Tools
If you don’t have a vacuum cleaner, you can use a small brush or a can of compressed air to remove dust in hard-to-reach places.
Step 2: Removing Stubborn Dirt
Remove the Buttons with a Small Screwdriver
Use a small flathead screwdriver to carefully remove the keyboard keys one at a time. Make sure you take a picture of the button layout before you start cleaning to make it easy to reinstall it.
Clean with Isopropyl Alcohol
Dip a cotton swab in isopropyl alcohol and use it to clean up any remaining dirt under the button. This alcohol is effective in removing oil and dirt and evaporates quickly without leaving a mark.
Reinstall Button
When you are done cleaning, carefully reinstall the button in its original position.
When to Replace the Keyboard
While many problems with the keyboard can be fixed, there are times when the damage is too severe and needs to be replaced. Here’s how to recognize when the right time is and choose a good substitute:
Signs of Damage That Can’t Be Repaired Yourself
1. Button Not Working
If some important buttons are not responding even though they have been cleaned or repaired, there may be a malfunction in the circuitry inside.
2. Serious Physical Cracks or Damage
Cracks in the keyboard, broken keys, or liquid damage that cannot be completely cleaned can be reasons to replace the device.
3. Connection or Reset Issues
If the keyboard isn’t detected even after replacing the cable, battery, or resetting, it indicates that the problem is with the device itself, not the computer.
4. Highly Visible Signs of Wear
Keyboards that are used frequently for a long time usually show signs of wear such as faded letters, loose keys, or decreased sensitivity.
