Are you frustrated with a non-functional keyboard on your laptop? Don’t worry; you’re not alone. A malfunctioning keyboard can be a significant hindrance to productivity, especially if you rely on your laptop for work or school. In this article, we’ll delve into the possible reasons why your keyboard may not be working and provide you with step-by-step solutions to get it up and running again.
Hardware-Related Issues
Before we dive into software-related problems, let’s explore some common hardware-related issues that might be causing your keyboard to malfunction.
Loose or Faulty Connection
If your laptop’s keyboard is not working, it’s possible that the connection between the keyboard and the motherboard is loose or faulty. This can be due to physical damage, wear and tear, or manufacturing defects.
To troubleshoot this issue, try the following:
- Shut down your laptop and unplug the power cord.
- Locate the keyboard connector, usually found under the keyboard or on the motherboard.
- Gently remove any debris or dust from the connector using compressed air or a soft brush.
- Reconnect the keyboard connector securely, making sure it’s properly seated.
- Reboot your laptop and test the keyboard.
Keyboard Damage or Wear and Tear
Physical damage or wear and tear can also cause your keyboard to malfunction. If you’ve spilled liquids on your keyboard or dropped your laptop, it’s possible that the keyboard is damaged.
To diagnose this issue, inspect your keyboard for any visible signs of damage, such as:
- Cracks or breaks in the keyboard keys or frame.
- Corrosion or rust on the keyboard circuitry.
- Sticky or jammed keys.
If you find any damage, you may need to replace your keyboard or have it repaired by a professional.
BIOS Settings
In some cases, the BIOS settings may be causing your keyboard to malfunction. The BIOS (Basic Input/Output System) is responsible for configuring your laptop’s hardware components, including the keyboard.
To check your BIOS settings, follow these steps:
- Restart your laptop and press the BIOS key (usually F2, F12, or Del) to enter the BIOS setup.
- Navigate to the “Advanced” or “Peripheral” tab.
- Look for the “Keyboard” or “Input Device” settings.
- Ensure that the keyboard is enabled and set to the correct port (e.g., PS/2 or USB).
- Save the changes and exit the BIOS setup.
Software-Related Issues
Now that we’ve explored hardware-related issues, let’s move on to software-related problems that might be causing your keyboard to malfunction.
Driver Issues
Outdated, corrupted, or missing keyboard drivers can cause your keyboard to stop working. To resolve this issue, try the following:
Update your keyboard drivers:

To uninstall software, follow these steps:
- Go to the Control Panel (Windows) or Applications folder (Mac).
- Find the software you want to uninstall.
- Click on the “Uninstall” or “Remove” button.

Run an SFC scan:
- Press the Windows key + X and select Command Prompt (Admin).
- Type the command “sfc /scannow” and press Enter.
- Wait for the scan to complete and follow any prompts to repair corrupted files.
Other Solutions
If none of the above solutions work, try the following:

Why is my laptop keyboard not working after a Windows update?
There are several reasons why your laptop keyboard may not be working after a Windows update. One possible reason is that the update may have caused a conflict with your keyboard drivers. This can happen if the update installed new drivers that are not compatible with your keyboard. Another reason could be that the update may have changed some settings that affect your keyboard’s functionality.
To resolve this issue, you can try rolling back the update or reinstalling the keyboard drivers. You can do this by going to the Device Manager, finding the keyboard device, and selecting the option to roll back the driver or uninstall it. You can also try restarting your laptop in safe mode to see if the keyboard works in that mode. If none of these solutions work, you may need to perform a system restore to a previous point when your keyboard was working properly.
How do I troubleshoot my laptop keyboard if it’s not working?
Troubleshooting a non-working laptop keyboard involves a series of steps to identify and resolve the issue. First, try restarting your laptop to see if the keyboard works after a reboot. If it doesn’t, try checking the keyboard connection to ensure it’s properly connected to the laptop. If your laptop has a removable keyboard, try disconnecting and reconnecting it. You can also try using an external keyboard to see if the issue is specific to the laptop keyboard.
If the issue persists, try checking for dust or debris under the keys and cleaning the keyboard. You can also try updating your keyboard drivers or reinstalling them if they’re outdated or corrupted. Additionally, check your laptop’s settings to ensure that the keyboard is enabled and not disabled. If none of these steps resolve the issue, you may need to contact a professional for further assistance or consider replacing the keyboard.
Can a dead battery cause my laptop keyboard to stop working?
A dead battery can cause your laptop keyboard to stop working, but it’s not the most common reason. If your laptop’s battery is completely drained, it may not have enough power to support the keyboard’s functionality. However, most modern laptops are designed to prioritize essential functions like the keyboard and touchpad, even when the battery is low.
If you suspect that a dead battery is causing your keyboard issues, try plugging in your laptop and charging the battery. If the keyboard starts working again after charging, it’s likely that the battery was the culprit. However, if the issue persists, it’s likely caused by a different factor, and you should try other troubleshooting steps to resolve the issue.
How do I fix my laptop keyboard if it’s not working due to liquid damage?
If your laptop keyboard is not working due to liquid damage, the first step is to turn off your laptop immediately and unplug it from the power source. This will prevent any short circuits that could cause further damage. Next, remove any accessories, including the battery, and turn your laptop upside down to drain out any liquid.
Once you’ve drained out the liquid, use a soft cloth or paper towel to gently pat the area dry. Avoid applying heat or using a hair dryer to speed up the drying process, as this can cause further damage. If the liquid damage is severe, you may need to take your laptop to a professional repair service to have the keyboard replaced or repaired. In some cases, you may need to replace the entire laptop if the damage is extensive.
Can a virus or malware cause my laptop keyboard to stop working?
Yes, a virus or malware can cause your laptop keyboard to stop working. Some types of malware can interfere with your keyboard’s functionality or disable it altogether. If you suspect that a virus or malware is causing your keyboard issues, run a full scan of your laptop using an anti-virus software.
If the scan detects any malware, follow the software’s instructions to remove it. You may also need to update your operating system and software to ensure you have the latest security patches. Additionally, consider resetting your laptop to its default settings or performing a system restore to a previous point when your keyboard was working properly. If the issue persists, you may need to seek professional help to resolve the issue.
