my Ativ became enemies with all my PC's and laptops quite a few months ago, i tried all the cures i could find for it here and elsewhere to no avail. the cure, if it was?? was to buy an android phone and put the non talking Ativ away to use as a stand alone spare if necessay. a month or two later when the phone battery was totally dead, along with any other internal electrical residues i connect it up to my laptop to charge it and magically it is talking again? woohoo! just wish i knew why for sure???
