Notebook keyboard no longer works – this could be the reason

If the notebook keyboard no longer works, there may be various reasons for this: from an activated keyboard lock to software or hardware defects.

Notebook keyboard no longer works: keyboard lock and physical reasons

If your laptop keyboard suddenly stops working, there may be a number of reasons behind it. Often, it is an accidentally locked keyboard or physical problems that can be easily fixed.

• Accidentally locked keyboard: Many laptops have a keyboard lock feature, which is often activated by a specific key combination. Look for an icon on the F1 to F12 keys that looks like a crossed-out keyboard or a lock. Then press the “Fn key” together with this key to unlock the keyboard.

• Keyboard contamination: Dust, crumbs or other foreign objects can collect under the keys and affect their function. Thoroughly cleaning the keyboard can often solve the problem. To do this, carefully use a flat-head screwdriver to loosen individual keys and clean the area under them with a keyboard cleaner.

• Liquid damage: If liquid has been spilled on the keyboard, this can cause individual keys or the entire keyboard to malfunction. In this case, professional cleaning or even replacement of the keyboard is necessary.

• Defective USB ports: With external keyboards, a defective USB port on the notebook can be the cause. Try connecting the keyboard to a different USB port or testing it on a different computer to rule out a defect in the port.

Hard- and software problems can disable your keyboard

In addition to physical problems, hardware and software problems can also cause your notebook keyboard to stop working. These problems are often less obvious, but in many cases can be solved by taking a few simple steps.

• Windows Settings: In some cases, an enabled keystroke delay in Windows can cause the keyboard to appear to be unresponsive. Go to Settings ☻ Ease of Access ☻ Keyboard and disable the “Keystroke delay”.
• BIOS issues: In rare cases, problems in the BIOS can cause the keyboard to not work. Restart the computer and press the appropriate key (often F2 or Del) during the startup process to access the BIOS. Check the settings for the keyboard there.
• System updates: After a Windows update, the keyboard may no longer work properly. Make sure you are running the latest version of Windows 10 or 11 and that all system-relevant drivers are up to date.
• Malware or viruses: Malware or viruses can also affect the function of the keyboard. Run a full virus scan with your anti-virus software to remove any possible malware.
• Hardware defect: If all other troubleshooting attempts fail, the keyboard may be defective. In this case, it is advisable to consult a specialist or consider purchasing a new keyboard.
