I am aware that nVidia drivers are not quite good with Vista and unfortunately me using Geforce Go 7300 and I have this Sleep (the default Vista shutdown) problem. My laptop (Dell Inspiron 6400 E1505) does not go to sleep and even hybrid sleep doesnt work and Dell has told that its nvidia vista driver problem and now I have no other choice than waiting for nvidia driver. Other than sleep, everything works fine...but I was using this Sleep feature always and was quite happy the way Vista improving their power options. And now I am not able to use it ! I have to shutdown my system all the time :(
Anyone aware of any solution ?
