We’ve investigated this particular issue thoroughly and we realized that there are several different underlying causes that might be responsible for the particular error. Here’s a shortlist of potential culprits that might be responsible for this particular error code: Now that you are aware of every potential reason why you might be suddenly noticing that the function keys stop working, let’s get to the actual fixes. Follow the instructions below for a few repair strategies that other affected users have successfully used to fix the functionality of the function keys on Windows 11.
Enabling the Function keys
When you’re troubleshooting this particular issue, the first thing you should do is check if the function keys are not actually hard disabled by a shortcut key. Keep in mind that most laptops have a dedicated function key shortcut that will allow you to disable the function keys at will – for some laptops is FN + F1, for others, it’s FN + F11 and for Dell models, it’s usually FN + ESC. Chances are you accidentally pressed this function key and ended up disabling this functionality without even realizing it. You can investigate if this is the case by pressing the function keys shortcut once again and see if you get the functionality back. Note: You can do an online search with ‘enable function keys + ‘laptop model’ and you should be able to find the shortcut you’re looking for. In case you already made sure that the function keys are enabled via the shortcut or your particular laptop doesn’t have an FN shortcut for deactivating the function keys, move down to the next potential fix below.
Enable Function keys from BIOS or UEFI Settings
Another reason why you might expect to deal with this particular issue immediately is a case where the function keys are actually disabled from your BIOS or UEFI settings. This type of change can most likely be enforced manually, but there are some cases (the most recent one is with ASUS) where a BIOS update ended up disabling the function keys. Fortunately, if you’re dealing with this particular issue, the fix is very simple – you’ll need to access your BIOS or UEFI settings and enable the function keys manually. Follow the instructions below for approximate instructions on how to do this: Note: While the process of accessing your BIOS settings is the same, your BIOS / UEFI screen will be different depending on your manufacturer. We can’t give you specific instructions once you reach the BIOS or UEFI menu (only general guides). If the problem is still not fixed, move down to the next potential fix below.
Install Windows 11 Build 22000.120 or over
Keep in mind that this behavior can also result from a Windows 11 glitch that got introduced along with build 22000.100. This bad update caused certain hardware keys and buttons not to work on some devices, particularly function keys. Although Microsoft has not given an official list of affected devices, they do seem like they managed to fix the issue starting with Windows 11 build 22000.120. So if you’re still on Windows 11 Build 22000.100 or 22000.110 and you didn’t upgrade yet to 22000.120 (or older), fixing this weird function key behavior should be as easy as installing every pending Windows update via WU. Follow the instructions below to bring your Windows 11 build to the latest and fix the Windows 11 function key glitch: If the same kind of problem is still occurring or you already had the latest updates installed, move down to the next potential fix below.
Reinstall the Lenovo Pointing Device (Lenovo Laptops Only)
Another potential reason why you might see this issue occurring is a situation where the function keys are unreachable due to a corrupted Lenovo Pointing Device driver. This is a well-known bug that was affecting Lenovo laptops on Windows 10 and it seems to have transitioned to the new Windows 11 too. Several affected users that we’re also dealing with this issue have confirmed that they managed to fix this issue by using Device Manager to uninstall the potentially corrupted driver. By doing this, you’ll end up forcing the Windows Update component to reinstall the driver at the next system startup (once your operating system realizes that it’s missing this driver) Follow the instructions below for a step-by-step guide on reinstalling the Lenovo Pointing Device Driver: If the same kind of issue is still occurring even after you follow the instructions above or this method was not applicable to your particular scenario, move down to the next potential fix below.
Clean install Official Windows 11 Release
If none of the instructions above have allowed you to fix the issue in your case and you’re on a development build, you should really think about making the transition to a stable release. Truth be told, insider builds will always be vulnerable to these kinds of issues, so if you don’t have any use for an insider build, you should really consider making the transition to a stable release. If you’re looking for specific instructions on performing a clean install procedure, follow this guide that will walk you through the whole thing.
