Some keys of Hp notebook keyboard stopped working

[VP31]

Hi. Some keys of my keyboard such as B, N, Del, Capslock stopped working. I have tried all possible ways HP engineer has suggested such as uninstalling drivers, removing battery, updating bios to default but could not get it worked. Can you please help?

Thank you for posting on the HP Support Community.
 

Use HP PC Hardware Diagnostics to complete functional test of the keyboard and identify any problems with the hardware.

1. Download the latest version of HP PC Hardware Diagnostics.

2. In Windows, search for and right-click HP PC Hardware Diagnostics for Windows, and then select Run as administrator.

   

3. Click Component Tests, click Input Devices, and then select the Keyboard Test.

   

4. Click Run once to begin the test.

   The test ends when you complete the tasks or after 3 minutes.

For more information about using the HP PC Hardware Diagnostics for Windows, go to HP PCs - Testing for Hardware Failures.
