Keyboard not working after windows update

[715647]

After a windows 11 update, my keyboard has not worked. I noted that the Keyboard is not visible in Device Manager list, despite my removing USB connection from PC, closing it down, reconnecting the USB back into PC and restarting it.

Hi @715647,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand how disruptive this is, especially right after a **Windows 11 update, when your keyboard suddenly stops working. Since the keyboard is not even showing in Device Manager, we’ll focus on connection, driver refresh, and system-level
 

Step 1: Basic hardware check

• Try plugging the keyboard into a different USB port (preferably on the back of the desktop) 
• Avoid USB hubs; connect it directly to the PC 
• If possible, test the keyboard on another computer 

👉 This helps confirm if the issue is with the keyboard or the system.

Step 2: Force Windows to detect hardware

Since it’s not listed in Device Manager:

1. Right-click Start → open Device Manager 
2. Click Action (top menu) 
3. Select Scan for hardware changes 

Check if the keyboard appears under:

• Keyboards 
• or Human Interface Devices 

Step 3: Enable USB ports in BIOS

Since your keyboard is not detected at all, we need to confirm that USB is active at the system level:

1. Restart the PC 
2. Tap Esc or F10 to enter BIOS 
3. Look for: 
   • USB Configuration 
   • Ensure USB ports are enabled 

👉 If the keyboard does not work in BIOS either, this points more toward:

• USB port issue, or 
• Keyboard failure 

Step 4: Run Hardware Diagnostics

1. Turn OFF the PC 
2. Turn it ON and tap Esc repeatedly 
3. Press F2 for Hardware Diagnostics 

Run:

Component Tests → Input Devices (Keyboard)

I hope this helps.

Take care and have an amazing day!
