Hi Prema, you're an absolute legend. Got my P650SG today (first clevo and n00b) and straight away flashed it with your BIOS and vBIOS. While the BIOS flash went okay, I think something may have gone wrong when flashing the vBIOS (I did make a GPUZ backup of the original BIOS though). I opened the 'update' file and it detected my 980m and I did as instructed - I uninstalled the NVidia drivers and opened, proceeded with 'y' twice and it beeped and the command window quickly closed. I restarted the computer, installed the drivers and the games appear to be working as they were, as too the GPU switching - but when opened the vBIOS 'update' file again it stated that it could not find an NVidia adapter - and when I forced a program to use the dGPU, the update command window gave me ' unconfigured display adapter found device not accessible ' and the window wouldn't close. Do you think I have a bad flash? Gaming works fine but how do you suppose I should proceed? thanks!
