What should I do if my keyboard keys are not responding at all?
If your keyboard is completely unresponsive, begin by checking the connection. If you are using a wired keyboard, ensure that the USB or PS/2 connector is securely plugged into the computer. For wireless keyboards, check if the device is powered on and ensure the USB receiver is properly connected. If the keyboard is connected but still unresponsive, consider trying it on another computer to determine if the issue lies with the keyboard itself.
In case the keyboard works on another device, the problem may be with your computer settings or drivers. Try updating or reinstalling the keyboard drivers through Device Manager. If the keyboard is not functional on any device, it might be time to consider a replacement or professional repair.
How can I check if the keyboard keys are physically stuck?
To check if any keys are physically stuck, visually inspect your keyboard. Press each key to see if they move freely. Sometimes debris, dust, or even spilled liquid can cause keys to stick. If you notice any foreign objects, gently remove them using compressed air or by tilting the keyboard upside down and shaking it lightly.
If cleaning doesn’t resolve the issue, you can disassemble the keycaps (if possible) and thoroughly clean the area underneath. Make sure to follow the keyboard manufacturer’s instructions for disassembly to avoid damage. If the keys still do not respond after cleaning, consider seeking professional help.

Yes, software issues can often impact keyboard functionality. Sometimes, recent software updates or installations can cause conflicts with drivers or settings. To troubleshoot, start by rebooting your computer, as this can resolve many transient software issues. If the problem persists, check the keyboard settings in your operating system’s control panel to ensure everything is configured correctly.
Another effective method is to run a keyboard troubleshooter, if available, in your operating system to identify and fix common problems. If you suspect a specific application might be causing the issue, try closing or reinstalling that application to see if it resolves the keyboard malfunction.
How do I clean my keyboard properly?
Cleaning your keyboard is essential for maintaining its functionality. Start by turning off your computer and unplugging the keyboard. Use compressed air to blow out any dirt or debris trapped between the keys. If there are sticky substances or grime, lightly dampen a microfiber cloth with isopropyl alcohol and gently wipe down the surfaces and edges of the keys.
For deeper cleaning, you might consider removing individual keycaps if your keyboard allows for it. Make sure to note the layout so you can easily reattach them later. Clean the exposed areas carefully, and ensure everything is dry before reassembling. Regular cleaning can prolong the lifespan of your keyboard and prevent issues arising from buildup.
Why are certain keys on my keyboard not working while others are fine?
If specific keys are not working, it could be due to physical damage or wear and tear in those areas. Sometimes, moisture or debris can affect only certain individual keys, causing them to malfunction. Inspect the affected keys closely for any visible signs of damage or obstruction. It may be necessary to clean once again or check for sticking.
Another possibility is that the keypress mappings have been altered through software settings. Some applications allow for remapping of keys, which can lead to confusion if changes have been made unintentionally. Check your keyboard settings or use a key-testing tool to help diagnose which specific keys are not registering, and look for any custom configurations that might be affecting them.
What if my laptop’s built-in keyboard is not working but an external keyboard is fine?

Begin by going to Device Manager on your computer and locating the keyboard section. Right-click on your keyboard entry and select the option to update the driver. Follow the prompts to search for updates automatically.
If the automatic update doesn’t solve your keyboard problems, you may also choose to uninstall the driver and restart your computer. The system will automatically reinstall the driver, which can address any corrupted file issues. Always ensure you are downloading drivers from official sources to avoid potential malware risks.
What should I do if the keys work in BIOS but not in the OS?
If your keyboard functions correctly in BIOS but fails to work within the operating system, the issue is likely software-related rather than hardware-related. A common first step is to boot your computer in safe mode. If the keyboard works in safe mode, it indicates that a driver or software conflict in the regular operating mode is causing the issue.
In such cases, check for any recently installed software or updates that could have interfered with your keyboard functionality. Rolling back drivers or uninstalling the last installed applications may help in troubleshooting. If all else fails, consider restoring the system to an earlier point when everything was functioning correctly.
