After rebooting the Lenovo U410 Touch laptop, the GeForce 710M is nonexistent. It doesn't exist in the device manager, and Nvidia GeForce experience (which i just downloaded) says I don't have an Nvidia card installed. Please help!
Hate to see that happen. It is most likely a goner
The last option you have is to enter your bios settings and disable the onboard graphics to force the use of the gpu. If this fails you need to get a new laptop (due to not being worth the trouble replacing a laptop gpu).
If you didn't own the laptop for very long, I would call the company to check if its under warranty for free replacement
