None responsive Keyboard and on screen keyboard

[Problemsolva]

I am unable to get any response from my Keyboard from this machine once it loads into windows. 

I have tried the built in Keyboard, the On screen keyboard and even used an external Keyboard but nothing 

The mouse and touch works. 

I can use the keys to get into bios and diagnostics. 

I ran the onboard diagnostics which showed a problem with the LEFT ALT key. 

can the keyboard be replaced?

Please Help.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, let's quickly run keyboard test in order to get the failure code.

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

NOTE: Bluetooth devices are not currently supported.

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.

Hope this helps! Keep me posted for further assistance.
