Settings Issues

Certain system or power settings can cause the keyboard on your computer to disconnect at inopportune times. For the sake of conserving power, certain energy-saving modes, for instance, could cut off USB ports when they detect a period of inactivity. It could be helpful to check these settings and make any necessary adjustments to keep the keyboard connection steady.

Connection Conflicts with Other Devices

If you have numerous input devices connected to your computer, they may clash with your keyboard, causing it to disconnect erratically. It can happen if there are many devices connected to your computer. Disconnecting input devices that aren’t essential can be an effective step in fixing this problem.

Electromagnetic Interference 

The functionality of your keyboard could be disrupted by electromagnetic interference (EMI), especially if it’s wireless. Other electronic or electrical equipment, devices, power lines, or weather phenomena can generate electromagnetic interference (EMI) that causes sporadic keyboard disconnections.

Incorrect Keyboard Settings

If the settings on the keyboard itself are incorrect, such as having a high polling rate or the wrong key rollover settings, the keyboard may disconnect from the computer. It’s possible that resetting your smartphone to its factory settings or altering its settings to match the device’s requirements would fix the issue.

Dust or Moisture

Dust accumulation or prolonged moisture exposure can also result in sporadic disconnections from the keyboard. You can avoid this problem to some extent by maintaining a dry environment for your keyboard and performing routine cleanings on it.

How To Fix a Keyboard That is Randomly Disconnecting?

You can fix it by checking the operating system’s compatibility, testing keyboards on other ports, checking for newly installed hardware, scanning the PC, updating drivers, changing power settings, unplugging conflicting devices, avoiding EMF, checking keyboard settings, and cleaning your keyboard.

Check Operating System’s Compatibility

To avoid compatibility issues between your keyboard and the operating system, ensure that your current version supports your keyboard.

Check the manufacturer’s website or the product documentation to see if any particular drivers or upgrades could be necessary. You can use a different keyboard compatible with your operating system if no particular drivers are available.

Test USB Keyboard on Other Ports

Connecting your keyboard directly to a USB port on your computer rather than going via an intermediary device such as a USB hub is the best way to resolve any disconnecting difficulties caused by a USB hub or port.

It will assist in removing any potential difficulties that incorrect connections or hubs of a low grade might have created. If you are still having problems, you may test your USB device on various ports on your computer to see whether the issue follows you.

Check For Newly Installed Hardware

If you recently installed new hardware that might create conflicts, consider temporarily unplugging the newly added device to see if the keyboard disconnections stop. It is especially important if you just recently installed the hardware.

If they do, the new piece of hardware you installed might not be compatible with the keyboard you already had. If so, you should probably update the device’s drivers or consider swapping out the incompatible component for a compliant one.

Scan Your PC Thoroughly

Use a reliable antivirus tool to comprehensively scan your computer’s system for any malware or viruses that could obstruct its performance.

You should carry out the procedures indicated to remove any potential dangers and ensure the safety of your system. After you remove the virus, you should check if the keyboard issues have been resolved.

Try Unplugging Conflicting Devices

Whether you have several input devices connected to your computer or not, you should try unplugging the input devices that are not required to see whether this resolves the issue with the keyboard. It will assist in determining whether conflicts between different devices cause the issue. Alternatively, you might eliminate conflicts by connecting each input device to a distinct USB port.

Avoid Electromagnetic Fields

Suppose you have reason to believe that electromagnetic interference is to blame for the disconnections. In that case, you should consider shifting the wireless receiver of your keyboard to a new position that is further away from any other electrical equipment or sources of electricity. It is best to avoid positioning the receiver near power lines or other electrical equipment that might produce EMI.

Check Keyboard Settings

Check your keyboard’s polling rate and key rollover settings to ensure they are adequate for your computer and the programs you use. If required, reset the keyboard settings to their original default values or alter them so that they are compatible with the specifications of your machine.
