Why can’t I detect my keyboard and mouse after booting?
Why can’t I detect my keyboard and mouse after booting?
I’ve been experiencing an issue where my keyboard and mouse are completely unresponsive after my computer boots up. This problem occurs consistently and has become quite frustrating. Initially, I thought it was a temporary glitch that would resolve itself, but it’s now clear that something more persistent is wrong. I’ve checked the physical connections to ensure everything is plugged in correctly, and I’ve attempted to restart the computer multiple times, but nothing seems to work. The keyboard and mouse work fine in the BIOS setup, which makes this issue even more perplexing. I rely heavily on my computer for daily tasks, and not being able to use the keyboard and mouse after it boots up has significantly disrupted my workflow. I’m hoping to find a detailed explanation of why this is happening and if there are any known issues or conflicts that could be causing this.

The problem could be with the BIOS settings, specifically the USB legacy support. I discovered this when I enabled the option for USB legacy support in BIOS.
Follow these steps:
1. Restart your computer and enter the BIOS setup (commonly by pressing F2, Delete, or the specified key).
2. Locate the USB configuration settings.
3. Enable USB legacy support.
4. Save the changes and exit BIOS.
5. Restart your computer to see if the issue is resolved.
You might be dealing with outdated or corrupted USB drivers. I’ve had a similar issue and updating the USB drivers did the trick for me.
Steps to update USB drivers:
1. Boot into Safe Mode by pressing F8 before Windows starts.
2. Open Device Manager (you can search for it in the Start menu).
3. Expand the ‘Universal Serial Bus controllers’ section.
4. Right-click each entry and select ‘Uninstall device’.
5. Restart your computer, and Windows should reinstall the necessary drivers automatically.
Another possible cause could be conflicts with external peripherals or docking stations. I faced a similar problem which was resolved by disconnecting my docking station.
Here’s what you should try:
1. Disconnect all external devices including printers, USB hubs, and docking stations.
2. Reboot your computer.
3. Check if the issue with the keyboard and mouse is resolved.
4. If it works, reconnect the devices one by one to identify which one is causing the conflict.
In my experience, disabling Fast Startup in Windows fixed the problem. This setting can sometimes cause issues with hardware detection.
To disable Fast Startup:
1. Open Control Panel and go to Power Options.
2. Click on “Choose what the power buttons do.”
3. Click on “Change settings that are currently unavailable.”
4. Uncheck “Turn on fast startup (recommended)” and save the changes.
5. Restart your computer to see if the issue is resolved.
Resetting BIOS settings to their defaults resolved the detection issue for me. This ensures no misconfiguration is affecting the startup.
Steps to reset BIOS:
1. Restart your computer and enter the BIOS setup (using the key like F2 or Del).
2. Find the option to reset to default settings (commonly found in the Exit or Restart menu).
3. Select this option and confirm your choice.
4. Save and exit the BIOS.
5. Check if the keyboard and mouse issue is resolved after the reboot.
Sometimes, a corrupted system file might be the culprit. Running a System File Checker scan can help identify and repair these corrupt files.
Here’s how you do it:
1. Boot into Safe Mode with Networking.
2. Open Command Prompt as an administrator (search for it in the Start menu).
3. Type sfc /scannow and hit Enter.
4. Let the System File Checker run; it will scan for and attempt to repair any corrupted files.
5. Once it’s complete, reboot your computer normally to see if the issue is resolved.
Conflicting third-party software might be causing the problem. For me, disabling startup programs helped identify and resolve the issue.
Steps to follow:
1. Boot into Safe Mode.
2. Open the Task Manager and go to the Startup tab.
3. Disable all non-essential startup programs.
4. Restart your computer to see if the keyboard and mouse work.
5. If the issue is fixed, re-enable each program one by one to find the problematic software.
A deeper hardware issue might be causing this. Performing a power drain can sometimes temporarily fix the problem, indicating a motherboard issue.
Here’s the process:
1. Power off your computer and unplug it from the power source.
2. Press and hold the power button for about 30 seconds.
3. Reconnect the power and boot your computer.
4. Check if the keyboard and mouse are now functional.
