Looking at your previous posts, are you referring to the IdeaPad Z710 model? If yes and the Z710 came with an Intel+Nvidia GPU then this uses the Nvidia Optimus technology to switch between the Integrated and discrete graphics.
I don't have a Z710 here with me for testing but ideally, there's an option in the BIOS to switch between UMA (Integrated Graphics) and Optimus (switchable graphics). In event that the Nvidia GPU is showing signs of failure, you can boot into the BIOS and temporarily disable the Nvidia GPU by changing the Graphic Device to UMA and still be able to use the laptop using the Integrated graphics.
Alternatively, you can also disable the Nvidia GPU under the Device Manager.
