I Have Inspiron 17R n7110 with 2nd Generation Intel® Core™ i5-2450M processor (2.50 GHz with Turbo Boost 2.0 up to 3.10 GHz), 8GB Dual Channel DDR3 1333MHz, NVIDIA® GeForce® GT 525M 2GB, 500GB SATA hard drive (5400RPM) and i'm running Windows 7 Ultimate 64 bits
I Want to Deactivate Intel HD Graphics and run all softwares and games with the NVIDIA GeForce GT 525M.
I Tried to deactivate it from the device manager but screen gets black and it get reabled after the reboot, and i didn't find options iin BIOS setup.
By the way, i tried to make the Nvidia as default Graphic card for all softwares but a game settings still work with low graphics so she still runs with Integrated one.
After a two-day search, i discovered the new Nvidia's technology "Optimus" that consists at starting with the IGP and switch to Nvidia GPU just when needed.
The problem is still the same: how to deactivate the Intel HD Graphics and work always with the Nvidia GPU ??
thanks ! but i solved my problem anyway. the driver of nvidia in the dell's site is not up to date. we nned to download the latest version from nvidia website and everything will be ok .
