@Puja001,

Thank you for posting your query on HP Community,

Have you recently made any software or hardware changes on the PC before the issue started?

Have you tried to use an alternate USB keyboard to check if that works?

Are other USB devices working on the computer? Did you try to connect the USB keyboard on another USB port.

Are you using a Wired connection or Wireless connection.

Could you please respond to this post with the details so that I can provide you with accurate solution which should help you resolve this issue. 

Eagerly waiting for your response!

Thank you 🙂

@Puja001,

Thank you for replying,

Have you tried checking with different USB devices?

Let's start off by updating the BIOS on your PC and check if it helps.
 

Please try the steps recommended below.
 
1. Open Device Manager.
2. Expand category “Universal Serial Bus controllers”.
3. Double-click the “USB Root Hub” device, and click the Power Management tab. (if there’s more than one USB Root Hub device, repeat these steps for each one.)
4. Turn off the Allow the computer to turn off this device to save power option, and click  OK button.

Disconnect all USB devices connected to the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
In Windows, search for and open Device Manager.
The Device Manager window opens.
Double-click Universal Serial Bus Controllers to expand the list.
Right-click the first USB Root Hub in the list, then select Uninstall.
Click OK to confirm.
Continue uninstalling all USB Root Hubs listed.
Close Device Manager and restart the computer.
If the USB device that is having problems came with software and it was not previously installed, install the software now, following the manufacturer instructions.
Reconnect the USB device that was having problems and test it to see if it works.

 
Open Device Manager (Right Click on Windows Logo and Click Device Manager).
Now find and expand Universal Serial Bus controllers. Now right click on USB drivers and click Uninstall. Do for all USB drivers one by one.
Now Restart your PC. The USB drivers are automatically re-install and solve the corrupted USB devices.
Right-click on the battery icon and click Power Options.
Click Change plan settings.
Now click Change advanced power settings.
Find and expand USB settings.
Expand USB selective suspend settings and Disable both On battery and Plugged in settings.
