Notebook Software and How To Questions

Keyboard and touchpad not responding at all. 

No lights on the CAPS lock. Noting gets typed, Windows button not responding either. Only the Power button seams to work when the computer is on. 

Wireless keyboard (with integrated touchepad) works fine when plugged via USB. The touchpad part of it works too, and I see and control the cursor via the wireless touchpad, but no response from the integrated trackpad.

Searched solutions :

A - Tried uninstalling all keyboard drivers (including the hidden peripherals in the Device Manager), then restarted the computer, to no avail.

B - Tried a Hard Reset: Turning off the computer, unplugging everything (peripherals and power supply), holding Power button for 15 seconds, then turning on the computer.

C - Tried B immediately followed by A.

D - Tried turning on the computer and passing by the BIOS by pressing Escape while powering up. It did open via BIOS and in BIOS, the keyboard is responding. I pressed F9 for a default setting, then saved the changes and quit the BIOS. Keyboard and touchpad not responsive when booted up.

Keyboard working in BIOS means the hardware of the keyboard is not broken. 

Laptop bought on december 2020. Warranty finished december 2021.  Laptop is mainly used for school stuff. Nothing weird happened before the keyboard not responding. I used it in the morning, trned it off, brought it to school and it did not work then.

I did the HP PC Hardware Diagnosis (in Windows) for the keyboard, the Touchpad (Drag &Drop) and the Touchpad (Pointer). Nothing happened. It says I have a critical failure in my system that requires repairs, which is wrong since the keyboard is working in the BIOS.

Here are the failure IDs anyway:

Touchpad(Drag&Drop):98AE21-000B19-XD7U3G-G1XA13
