I flash the Prema Mod, and reinstall my windows in UEFI Mod, with that i put the dGPU to always ENABLE (the default is AUTO). Now all work again. tks to all.

Sorry for the bad english... I have a AVELL (The Clevo Reseller in Brazil), the Nvidia update the driver a one week ago and cause a BSoD (Windows 8.1) when I was playing wow using the Battery. After that the Nvidia Driver dont show more in the Devices Manager, I unistall the driver, install again but windows dont recognize the gpu. I restart a lot of times and when a change the power manager to PERFOMACE the GPU back... well, i update again my nvidia driver, and again play, and again BSod when the Energy Cord was turned off... this time, the Nividia dont show up again, i change the bios to Prema Mod, change the switch Graphics to BACO, and change the dGPU to ENABLED... sometimes the GPU show up again in the devices manager with the Microsoft Default Driver I install the Nvidai Driver, and when I reset the Driver again gone... Someone can help me? Clevo P150 with Geforce GTX 770M
