Elitebook 840 g6 Touch screen not working.

[Udemzy]

Hello, I want to know if there's a way one can make touch screen work after building bios file.

I notice the touch function stop working both in bios setup and on windows after reprogramming the bios file, this is not the first time of experiencing.
The model of the laptop is Elitebook 840 g6,is there a way to resolve this?
