HP Recommended
Product: 840 G4
Operating System: Microsoft Windows 10 (64-bit)

Hi,

I have 2 - 840 G4's that had various damage. So I took parts from both and made 1 working notebook with no damage. However the now working notebook didn't originally have a touch screen panel. It had the 1366X768 screen. I put the FHD touch panel in and it plugged in and it works, but the touch device option is missing in the bios. It should be under Advanced, Built in Device Options, Touch Device; right under the Fingerprint Device check box but it's not there.

 

I flashed the latest bios and also reverted to a previous version but it doesn't show up. I'm pretty sure I know the answer to this but thought I would ask if it's possible to get this option to show up.

 

The connector for the touch panel is on the motherboard and it plugged in just fine. I wonder if a chip on the motherboard might be missing.

 

Any insight on this woudl be helpful. The tocuh panel worked on the notebook it came from.

 

Thanks,

John
