Spere Posted December 3, 2014 Share Posted December 3, 2014 Laptop: M17x R4dGPU: stock 7970mCCC: 14Bios: stock A12Currently the fn-F7 does not bring up the reboot screen. To the best of my knowledge is does nothing at all.Other osd functions appear to work fine. Latest osd version is installed.Is there a command line equivalent? What exactly does the Fn-F7 routine do? Does it reset a BIOS switch otherwise hidden, set a driver flag, test user anger management, or something else entirely? Thanks. Quote Link to comment Share on other sites More sharing options...
Spere Posted December 3, 2014 Author Share Posted December 3, 2014 A bit more digging and I came up with the following:%ProgramFiles(x86)%\Alienware On-Screen Display\SwitchGPU.exe--- running this provides the same functionality as the Fn-F7 keypressSo, now that only the 7970m shows up in Win 8.0 Device Manager and GPUz, I have a followup question for those that might know. Are there any critical differences between disabling the iGPU this way and through an unlocked BIOS? Quote Link to comment Share on other sites More sharing options...
