and i realized the main reason for its recurrence on trail and error basis. however after few days the problem recurred. this time i uninstalled the NVIDIA graphics driver from control panel and reinstalled it, restarting my PC two times, bot after uninstallation and reinstallation. but after a wk when i started playing a game the problem had recurred. I am about ready to start commiting violence against my computer.ġst i thought it could be windows 8.1, so i installed windows 7 professional and things started working. Tried taking battery out to be sure I was running on charger Found only the option to choose between Integrated and Integrated+Dedicated Uninstalled and Reinstalled current versions of Intel and NVIDIA Graphics Software Installed Lenovo outdated Intel and NVIDIA drivers Set power management to High Performance Set the power management to High Performance Set the global preferred GPU to High Performance NVIDIA GPU I suspect it MIGHT'VE started when my NVIDIA software ran an update as shortly after is when I noticed I wasn't running on dedicated graphics. I can't really pinpoint any single event that would cause my issue but about a week or so ago, no matter which program I run or settings I use, my Intel HD 4600 is the only GPU that is being used. My 1 month old Y410P was functioning perfectly in that games were actually running on the GT755M instead of the Intel HD 4600.
