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?

There are some touch screen settings in the EC_Bios (on some models) ,if you have removed a password by editing the EC_Bios NvramActiveRegion the touchscreen setting is gone. I`m not sure if it can be edited back in afterwards. If not then use a bios + EC_Bios (or EC_Bios only) dump from a touchscreen model
