A keyboard that stops working can be frustrating. Whether it’s a laptop or computer keyboard, the issue can disrupt your work or entertainment. This article explains why your keyboard isn’t working and provides step-by-step solutions to fix it.
Part 1. Why is My Keyboard Not Working?
Keyboards can stop working for various reasons. Identifying the cause is the first step to fixing the problem. Below are the most common reasons:
Loose or Disconnected Cable: For external keyboards, the USB or PS/2 cable might be loose or unplugged.#
Driver Issues: Outdated or corrupted drivers can prevent the keyboard from functioning.
Software Glitches: System updates or software conflicts can cause keyboard malfunctions.
Dirt or Debris: Dust, crumbs, or liquid spills can block the keys or damage the internal components.
Hardware Damage: Physical damage to the keyboard or laptop can render it unusable.
Battery Issues (Wireless Keyboards): Dead or low batteries can cause wireless keyboards to stop working.
Keyboard Lock: Accidentally enabling keyboard lock or filter keys can disable typing.
Part 2. How Do I Fix My Keyboard Not Typing?
Once you've identified the possible cause for the keyboard not working on your PC or laptop, follow these steps to fix your keyboard:
Way 1. Check The Hardware Connection Problems
1. Whether the keyboard is plugged in
If you are using a wired keyboard, first check whether the USB port is plugged in tightly. If the interface is loose, the keyboard may malfunction intermittently. You can try plugging the keyboard into another USB port to rule out interface damage.
For wireless keyboards, make sure the USB receiver is properly plugged into the computer and check that the distance between the keyboard and the receiver is not too far. A weak wireless signal may cause the keyboard to be unresponsive.
2. Dead Battery
Wireless keyboards rely on battery power. If the keyboard is unresponsive or does not work at all, the battery is probably low. Test the keyboard again by replacing the battery with a new one or charging the internal battery.
3. Physical Damage or Aging
The keyboard may have been damaged by prolonged use. Check the keys of the keyboard for stuck keys or moisture. If the keyboard has been accidentally exposed to water, it may need to be dried thoroughly before attempting to use it again.
Way 2. Driver Problems
The keyboard driver is the key to its proper functioning. If the driver is wrong, the keyboard may not work properly. Using Driver Sentry to automatically detect and update drivers can save time and prevent downloading the wrong drivers.
Download and install the latest version of Driver Sentry. Open the software and click "Scan".
After scanning, locate the keyboard driver in the results and click "Upgrade".
After updating, restart your computer to ensure the new driver takes effect.
Way 3. System Setup Issues
1. Whether the key filter function is enabled or not
The "Key Filter" function in Windows system may cause the keyboard to malfunction. You can turn it off by following the steps below:
Open "Control Panel".
Click on "Ease of Access Center" > "Make the keyboard easier to use".
Make sure "Enable key filtering" is not checked.
2. Incompatibility due to system updates
Some system updates may cause the keyboard to not work properly. If you are having problems with your keyboard after a system update, you can try to roll back to the system version before the update. Go to "Settings" > "Update & Security" > "Restore" and follow the instructions to restore your system.
Way 4. Software Conflict or Virus Problem
1. Check background programs
Some applications may lock the keyboard input and prevent you from using the keyboard. Press Ctrl + Shift + Esc to open Task Manager, end the suspicious process, and then test whether the keyboard is back to normal.
2. Effect of virus or malware
Virus infection may cause the keyboard to malfunction. Run antivirus software to perform a full scan of the system to remove malicious programs that may affect the function of the keyboard.
Way 5. Hardware Incompatibility or Motherboard Problems
1. Keyboard and computer compatibility
Some older models of keyboards may not be compatible with newer devices. If you are using an old PS/2 interface keyboard and your computer does not have a corresponding interface, you may need a converter to use it.
2. Insufficient power supply from motherboard or USB port
If the keyboard suddenly loses power, it may be due to insufficient power supply from the motherboard. Try connecting other devices to confirm that the USB port is properly powered. If the problem occurs frequently, you may need to check the motherboard or replace the power supply.
Way 6. Try Replacing The Keyboard
If you try the above methods still can not solve the problem, you can try to connect the keyboard to another computer. If the keyboard still does not work on the other computer, you may need to replace the keyboard. If it works fine on the other computer, then the problem may be on your computer.
