hello all, after upgrading to vista on my Acer C112Ti tablet pc, the bluetooth module (T60M665 , by Ambit) can not be detected in vista. using hardware scoping software like everest, there is no device attached to Intel 82801DB ..USB controller 24C7. function buttons like email, orientation-change also can not be recognized. and modem can be detected but no correct driver can be found. on acer website, it does not contain vista upgrade support for C112Ti. BUT they have vista upgrade for C200 series. i tried to install new C200 vista upgrade - LManager. and the functions keys work now (but keyboard stop to respond). i think i can do something later to fix the keyboard thing. for now, i am eager to know how to enable bluetooth on C112. i guess C112 has the same bluetooth module as C200 series(model should be TMC204TMi ) if so, we(I) can fix bluetooth problem also and C112 can have a vista OS finally. thanks.
