USB Keyboard Disconnects Randomly Every Days: Troubleshooting
You are working on your PC, and suddenly you hear the hardware disconnect sound. Your keyboard becomes completely unresponsive, and the lights on the keyboard stay on. This can be frustrating, and you might be wondering what could be causing this issue and how to fix it. This article will discuss the possible causes and provide troubleshooting steps to help you resolve the issue.
Possible Causes
There are several possible causes for a USB keyboard that disconnects randomly. Some of the most common causes include:
- Faulty USB port
- Outdated or corrupted USB drivers
- Interference from other devices
- Power management settings
- Hardware failure
Troubleshooting Steps
To troubleshoot the issue, follow the steps below in order:
Step 1: Check the USB Port
The first step is to check the USB port where the keyboard is connected. Try connecting the keyboard to a different USB port to see if the issue persists. If the keyboard works on a different USB port, then the issue is with the original USB port.
Step 2: Update USB Drivers
If the keyboard still disconnects randomly, the next step is to update the USB drivers. Here's how to do it:
- Press the Windows key + X and select Device Manager.
- Expand the Universal Serial Bus controllers section.
- Right-click on each USB controller and select Update driver.
- Select Search automatically for updated driver software and follow the prompts to install the updates.
Step 3: Disable Power Management Settings
Power management settings can cause USB devices to disconnect randomly. To disable power management settings, follow these steps:
- Press the Windows key + X and select Device Manager.
- Expand the Universal Serial Bus controllers section.
- Right-click on each USB controller and select Properties.
- Click on the Power Management tab.
- Uncheck the box next to Allow the computer to turn off this device to save power.
- Click OK to save the changes.
Step 4: Check for Interference
Other devices can interfere with the USB keyboard, causing it to disconnect randomly. Try disconnecting other devices that are connected to the USB ports to see if the issue persists.
Step 5: Test the Keyboard
If none of the above steps work, try testing the keyboard on a different computer to see if it works. If the keyboard works on a different computer, then the issue is with the original computer. If the keyboard still disconnects randomly, then the issue is with the keyboard itself, and you might need to replace it.
