,I have a Sony Vaio VPCSB1HE which meets all the criteria for Widi. When I first got the laptop Widi worked fine on Windows 7. I upgraded to Windows 8 and it worked fine. I upgraded to Windows 8.1 and all was well. However the OS crashed and I had to rebuild Windows 8.1 from scratch from the MS download site. This was straightforward. I installed all the 8.1 drivers on the Sony site and have run the Intel update tool which confirms everything is up to date. However, I cannot get Widi to work.I have tried uninstalling and reinstalling the drivers and the sequence in which I load them. If I run the Intel Widi update tool it reports that my system is not compatible with Widi. My system is second generation i7 with Intel HD3000/AMD 6600 graphics and Intel Centrino N1000 wireless. I have tried disabling the AMD graphics but it has not helped. Any advice would be much appreciated.
