HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Click the DOWNLOAD button.
The version of the UEFI diagnostics is shown at the left of that DOWNLOAD button.
When you press F2 to run diagnostics please ensure the version is the new one.

If no failure then windows drivers or file corruption could be the problem.

1 - Bring up the device manager and delete the touch screen driver then reboot.

2 - SFC and DISM are both tools that scan and repair corrupted system files. However, SFC uses a cached version of the files, while DISM uses the internet to download and fix the files.

Try the SFC first and if it gives a message that it cannot fix the problem then try the DISM tool.

It would be useful to know the exact model or product ID of you laptops.

Let me know what you find out.
