Running an Elitebook 2740p with Win 8.1, 4 GB, standard all else hardware. All seems fine EXCEPT for virtually nonexistent touch functions, fingerprint scanner not showing software and HPSA which will NOT run no matter how many times I install and uninstall it, how many different versions of the file I download (all of them, trust me), whether or not I choose to run it as an administrator and whether or not I try and run it in some compatibility mode. "This Application has encountered a serious problem and must close. Click OK..."
Nor is there mention of a single 8.1 file update of ANY type for the 2740p on HP's website, which sees this as a Win 7 machine, and I have registered this serial number. 2740p is listed elsewhere as Win 8 compatible, but to that I must add "sort of, maybe". May have to go back to Win 7, but I'd sure like some word from HP before making the trek back. Pen works fine, touch is a disaster and yes I have tried synchronizing and changing settings. I am always open to suggestions...
