Keyboard not working correctly

[century1]

every time the number 1 is typed the number 2 comes up as well 12. the same apply to letters q,a,z, each time they are keyed  I get qw,as,zx. It works the oposite as well. All other keys are fine. I have tried uninstalling the driver and that has not solved the problem.

I have an external USB keyboard which works fine.

I have seen this exact problem posted before but can not find the solution.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?
• What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824

While you respond to that, let's try these steps: 

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.
