The keyboard is a computer’s mouthpiece, and the entire device becomes useless if it stops working. Because of its importance, you should know what to look for in the best keyboards and how to troubleshoot if things go awry. So, if your keyboard stops working randomly, we’ll explore some of the causes and what you can do to get it back to normal below.


  • When a keyboard stops working randomly, it’s usually a connection or software issue.
  • Check all physical connections for any dirt or broken parts. Also, test the wireless connection to ensure it’s not cutting out.

Why Does My Keyboard Randomly Stop Working?

Keyboards might stop working for many reasons. However, some are more common than others. The most likely culprit of a spotty keyboard is a connection, settings, or software issue. Of course, hardware issues are never out of the question.

Check Connections

The first thing to look for is connection issues for those using an external keyboard. An external keyboard relies on a solid connection, whether a USB cable or wireless model. If there is a weak wireless signal or loose keyboard input, you’ll experience random outages. For wireless keyboards, you can also try replacing the batteries and ensuring the dongle is securely in its port.

Update/Reinstall Keyboard Driver

The keyboard driver communicates commands from hardware to software. It needs to be updated to maintain the best software features and keep your computer free of bugs. For PCs running on Windows OS, the process is simple:

  1. Press the key combo “Windows + R.”
  2. In the search bar, type “devmgmt.msc” and press OK.
  3. Find the keyboard icon and open the dropdown menu. Then click on the keyboard option that you use.
  4. At the top of the screen that pops up, there will be a tab that says “Drivers.” Click on that.
  5. You can check for and install any updates or uninstall and reinstall it to its default settings.

Clean Keyboard Switches

A common but fixable hardware issue is dirty keyboard switches. To fix this, take a can of compressed air and spray down your keyboard from multiple angles.


Be gentle when removing keycaps. The underlying keyboard switch has some delicate parts that can be damaged by rough handling.

If you had a liquid spill, remove the keycaps and wipe down the switches with rubbing alcohol. Then let everything dry before replacing the keys.

STAT: Wireless keyboards batteries last for 3-6 months, on average. (source)
