I have a Lenovo Y500. After updating windows to 8.1 I can no longer see my second graphics card. On Lenovo's support site they have "NVIDIA GeForce GT650M Second VGA BIOS Update for Windows 8.1 (64-bit) - IdeaPad Y400, Y500". But I can't get it to work.
these are the instructions included in the download:
1 Keep machine in AC mode with at least 35% Battery
2 Right click ProtectOff.bat and run as administrator;
3 Need to choose "1" for 2nd VGA option;
4 2nd VGA Protect function is off;
5 Double click the tool 2ndVGA_Winflash_Yx00.exe, and system will open CMD.exe;
6 Press Y to start upgrade 2nd VGA firmware;
7 When finish over, please reboot system.
When I get to step 2 and run as administrator the command prompt opens and immediately closes. At no point do I get a chance to do step 3.
Any help would be appreciated.
Thank you for your time.
