An unresponsive keyboard means you’ll find it challenging to complete your tasks, input your passwords, and navigate some parts of your computer.

In this guide, we’ll discuss the potential reasons why your Lenovo laptop keyboards aren’t working and how to reset a Lenovo laptop keyboard. Read on as we share valuable insights from our computer experts on how to resolve this problem.

How To Fix Lenovo Laptop Keyboard Not Working

There are many different methods to resolve the keyboard on Lenovo not working problem. We’ll work our way down the list of solutions from basic troubleshooting steps to more technical aspects.

– Restart Your Computer

There have been cases where continuous hibernation of a laptop has caused some minor inconveniences, such as slow responses, low speed, and even unresponsive keyboards. If you’ve been hibernating your computer a lot instead of doing a complete shutdown, your Lenovo number keys not working may come up as a result.

A simple restart or a complete shutdown can help resolve the issue.

– Unplug All Connected Devices

If you notice your keys not working on your Lenovo laptop after connecting some external devices to your laptop, then that device or its driver might be the problem. The driver of that device may share some similar properties with your keyboard driver, thereby causing a conflict.

To fix this problem, unplug all connected devices, such as external HDD, keyboard, mouse, CD-ROM, etc., restart your computer, and check if the problem has been resolved.

– Disconnect Your Laptop From the Internet

If your Lenovo computer is low on RAM, it’ll become very slow and may not be very responsive. Opening browsers, downloading files, conducting updates, and other tasks that have to do with the internet are tasks that eat up your computer’s speed.

And if you’re a serial hibernator, the problem becomes even worse as the speed will become quite slow, and your keyboard response may be so slow it’ll look like it’s malfunctioning or not working.

Disconnecting your laptop from the internet and restarting your PC might help you resolve the problem.

– Open the Troubleshooting Wizard

The Windows operating system is designed to resolve some minor issues by itself, and one of the best ways it does that is through the troubleshooting wizard. Launching this wizard can help you determine the exact problem and how to fix it immediately.

Keyboard Troubleshooting

The troubleshooting wizard will run a system scan to detect any software or hardware-related problem that may cause your Lenovo laptop keyboard not working.

Follow the steps below to reset a Lenovo laptop keyboard with the troubleshooting wizard:

  • Click on the search icon or search bar beside your start menu
  • Search for “Troubleshoot” and select “Troubleshoot settings”
  • Select “Other Troubleshooters” scroll down and search for “Keyboard”
  • Click on Keyboard and choose “Run Troubleshooter”
  • Select “Next” and the troubleshooter will automatically start checking for issues with your keyboard

If there are any technical reasons why your Lenovo laptop keyboard is not working, the troubleshooter will find it and notify you. It can also apply solutions by itself, but you’ll need to be connected to the internet. If the problem is still unresolved after running the troubleshooter, the next solution may be your stop.

– Check for Multiple Keyboards

It’s no news that everyone has a type of keyboard they prefer. If your Lenovo laptop doesn’t come with a keyboard you like, it’s only ideal that you use an external keyboard that serves you properly, especially if you do heavy typing jobs.

However, installing multiple keyboards on a computer can lead to conflicts and crashes between your keyboards because they all have varying drivers that do similar jobs. An improper installation of one or more external keyboards may be why you’re experiencing the keyboard on Lenovo not working problem.

You may need to uninstall these keyboard drivers so your laptop keyboard can work correctly.

All you have to do is:

  • Right-click on your start menu and select “Device Manager” from the context menu
  • Expand the “Keyboards” section to reveal all keyboard drivers on your computer
  • Make sure you’ve disconnected all external keyboards
  • Right-click on the driver that’s connected to your external keyboard and choose “Uninstall”Uninstall keyboard
  • Restart your computer after the uninstallation process is complete

Now, check if your normal keyboard is working properly. If it works, you may need to find a different external keyboard to connect to your laptop.

You can also try re-installing the external keyboard you have after some time. But if you get the same problem again, then it’s safe to say that the keyboard isn’t compatible with your Lenovo laptop.

– Update Your Keyboard Driver

An outdated keyboard driver may be the reason why you’re experiencing keys not working on Lenovo laptop. You need to make sure your drivers are constantly updated so that they’ll be able to communicate easily with the rest of your computer’s hardware.

Follow the steps below to safely update your keyboard driver:

  • Right-click on your start menu and choose “Device Manager” from the list of options
  • Select “Keyboards” to expand the list of keyboards available on your laptop

  • If there’s an update available, it’ll be automatically downloaded to your computer
  • Follow the prompts to install the update
  • Restart your computer after the installation is complete

Alternatively, you can download the driver from Lenovo’s website and install it manually. Once you’ve downloaded the keyboard driver update for your Lenovo laptop, follow the steps outlined above but this time, choose to install the update manually from your local directory.

You’ll be prompted to choose the file from where it’s saved on your computer. Once you’ve done that, follow the installation wizard to completely install the update.

– Reset the Keyboard Filter Settings

You may need to reset a Lenovo laptop keyboard filter settings to make your keyboard work again. A third-party app may have made wrong configurations on your device, leading to a change in filter key settings. Another user can trigger this problem, leaving you with a malfunctioning keyboard.

You can reset the filter key settings by following the steps outlined below:

Once you’ve toggled on or off the filter keys button, your keyboard will be back to its default state, and the keys not working on your Lenovo laptop should begin to function properly.

– Turn Off Cortana

Many users have found their keyboards to be unresponsive after or while using Cortana. You may need to end Cortana via the task manager to get your keyboard to work again.

CTF Loader, otherwise known as the Collaborative Translation Framework Loader, is a framework in Windows that helps alternative input devices to function properly.

If the CTF Loader is active and you don’t use other input devices, such as on-screen keyboards, voice function, or touch pen, then it may become conflicted with your normal keyboard processes, thereby causing you to experience the “keys not working” problem on Lenovo laptop.

You can close the CTF Loader by utilizing the steps below:

  • Follow the prompts from the installation wizard to completely uninstall the driver
  • Go to Lenovo’s support website and download the keyboard driver for the laptop model
  • Install the driver and check whether or not your keyboard now works properly

– Perform a System Update

Windows provides periodic updates to its operating systems. An outdated Windows OS can cause your keyboard keys to malfunction. Although Windows tends to update itself most times, there are situations where it can’t, and your OS becomes outdated.

You may have deferred OS updates, set your network to a metered connection, lack disk space, or have an unstable internet connection. Updating your computer manually may help resolve why the keyboard on your Lenovo laptop won’t work.

  • Once the download is completed, you’ll be asked to restart your laptop to install the update
  • Your computer may restart multiple times during installation, so there’s no need for you to be alarmed
  • Once the installation is complete and your laptop boots back up, check to see if your keyboard is working

– Use the Unlock Button or Button Combinations

Some Lenovo laptops have a keypad lock button that locks the keyboard as well as a num lock button that locks the number pad. These buttons are often denoted with a padlock sign on them. However, some do not feature this sign, and you may accidentally lock your keyboard.

If your Lenovo number keys are not working, simply pressing the num lock button should resolve the issue. And if your computer comes with a key that has a lock sign on it, pressing the key might be the solution to your locked keyboard.

However, for those who don’t have a key with a lock sign, you can try the combination of keys below to see if it’ll work for your computer:

  • Shut down your computer and unplug the power adapter
  • Press and hold down the S, V, and Fn keys for about ten seconds while the laptop is off
  • Now, press and hold your power button for about 60 seconds
  • Doing all of these will reset your keyboard to its default setting
  • Power on your laptop and check to see if your keyboard works correctly

Note that some Lenovo laptops will require you to press the S, V, and AltGr keys for about 15 seconds while the laptop is off.
