I am using HP 250 G7 Notebook model and the operating system is Windows 11.

I have been facing a problem since 14th July 2024. 

The problem is that I am unable to use my "delete" button though its hardware is alright, I have tried a few steps to fix it but it did not help me so please resolve my problem.

Have you run diagnostics?
Tap the ESC key after powering on. . Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics.

If there is not keyboard test then download the latest UEFI diagnostics

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',
Expand the'+'symbol and 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 the delete key fails to work in the diagnostic test then it or the keyboard needs to be replaced.

Let me know what you find out and if you are still in the warranty period

After one second of flash in the keyboard I pressed ESC button but there is nothing but only normal power on.

There was no interface as you told.
