HP Elitebook 820 G3
Microsoft Windows 10 (64-bit)

Hello awesome people.

I have an HP elitebook 820 G3 and I recently bought the Whole upper part (lid plus touch screen Along with antenna wires and display cable) and I fixed it on my laptop which originally does not have a touch screen. 
Now, the touch screen is not working 

Do I need to manually flash the bios? Since a bios update did not help

Many thanks
