Not sure if you have the N56JN (very impressive laptop BTW) but I found few things that may be of interest to you. One, there are 3 BIOS versions out there for it.201, 202, and 203 here. The BIOS descriptions (fixes) are as follows_ BIOS 201 Update NV VBIOS. BIOS 202 Support Foxccon wifi combo card (T77Z371). BIOS 203 Update NV VBIOS So you may want to check what BIOS you are currently using. I also found a utility that supposedly goes with a W10 install, and it is likely already included with your W8.1 restore media. It's called "ATK" found here. Description of said is as follows_ ATKPackage (For Windows 10 Upgrade) ATKPackage includes ATKACPI driver and hotkey-related utilities. To avoid displaying OSD abnormally due to compatibility issue after upgrade to Windows 10, please update ATKPackage to v1.0.0038 or above. Now if I had this problem the first thing I would do is take note of the BIOS version, and see if I was updated to the latest one, because two of them have the "NV" fix, which I assune they are referencing the nVidia GPU solution the notebook has, and yes if the original GPU solution (via GPU BIOS) was not working properly in it's default state it could interfere with coming out of sleep mode properly. Two of the BIOS versions seem to address that.
