The backspace key on your laptop or external keyboard can stop working due to both software and hardware issues. If only the Backspace key is not working, it points to a hardware fault. But it is also possible that some software component is preventing just this key alone from functioning properly.
Attach Another Keyboard
Before you begin with the solutions below, you should attempt to narrow down the possible cause. You can start by attaching another keyboard to your computer and check if its Backspace button works.
If yes, the key on your original keyboard is likely damaged or has some issues that prevent the computer from detecting the keystrokes. If it’s a laptop keyboard, it may also be because of bugs in drivers or some update issue.
But if the key on the other keyboard doesn’t work as well, conflicts due to other applications (mainly apps that canremap key functionsor add shortcuts) or update issues are more probable.
Replace Batteries in Wireless keyboard
If you are using a Wireless or Bluetooth keyboard and your Backspace along with some other keys are not working, it is possible that the batteries are almost fully drained. So, you should replace the batteries with new ones and check if the keyboard starts working.
Run Keyboard Troubleshooter
You can also try running the Keyboard Troubleshooter if the key is not working. It will automatically detect inconsistencies with the system components required to operate the keyboard.
Reinstall Keyboard Drivers
Another possible reason for this issue includes corrupt keyboard drivers. In such cases, some other keys, like Space and Enter, will also show similar issues. Here, you need toreinstall the driversto resolve any bugs in their software.
Check Keyboard Accessibility Settings
In some previous Windows versions, enabling some Accessibility settings like Sticky keys andFilter keyswas responsible for particular keys not working. So you can try disabling this setting.
Perform Clean Boot
Some applications can specify alternate shortcut combinations in the Windows shell, not just while running the app. And if you use such apps and they set Backspace as some shortcut key, you won’t be able to use its default function.
If you know which application it is, you can change its settings accordingly. If not, you need to clean boot your Windows so you can find out the app.
Restart your computer and check if the Backspace key works now. If not, some other causes should be responsible. So, revert these configurations to how they were and move on.
Otherwise, you should start looking for the conflicting application. To do so,
After narrowing down the culprit, you may change its settings or disable it depending on your situation to resolve your issue.
Update or Rollback Windows
If you started encountering this issue after updating your system, chances are that the update itself carried some errors. Microsoft will soon patch such issues, so you only need to wait for further updates. After they are available, you canmanually install themthrough the Update Settings.
If further updates are not available yet, you can uninstall the bad update and roll back your system for the time being.
Check Key Hardware
Hardware faults can also be responsible for some keys not working. It may be blockage due to dust build-up or damage to the key’s internal components. Or the Backspace key may be shorted with other keys on the keyboard.
You can also try running a hardware diagnostic test that the motherboard or keyboard manufacturer provides to get more information on hardware faults. If it shows no errors, the problem is likely with the key only, not the keyboard.
You can trycleaning the keyboardusing compressed air and a soft-bristle brush in such cases. If the key still shows some errors, we recommend taking the laptop or the keyboard to the service center for repairs or replacement.
