Hi all,
Some laptops come with dedicated gpus while some laptops come with integrated gpu.
I bought a Sony Vaio laptop with Intel core i5-2450 and Nvidia graphics card....
Does my laptop graphics( like windows aero) work even If I disable the Nvidia driver....
What do I have to in order to make it work like that.....
Does it work if I install Intel graphics drivers.....?
Thanks in advance...

Brief practical answer for (and thanks to and for the background): the desktop and Windows Aero will continue to work with the Intel integrated GPU alone as long as a proper Intel graphics driver is installed and the laptop’s display is actually routed through the Intel hardware. Many VAIOs of that era pair the CPU’s Intel graphics with an NVIDIA discrete card (Optimus-style): Intel drives the panel and NVIDIA is used when an app requests it. In that setup disabling NVIDIA simply leaves the Intel driver to handle the desktop and Aero.

How to proceed safely:

  • Check Device Manager → Display adapters to confirm both an Intel entry and an NVIDIA entry (or whether Windows is using the “Microsoft Basic Display Adapter”).
  • If Intel isn’t installed or shows the basic driver, install the Intel graphics driver that matches the OS (preferably the model-specific driver from Sony for VPCEH3AEN). Reboot.
  • To force integrated-only rendering, use the NVIDIA Control Panel to prefer the integrated GPU for global or per‑application settings, or disable the NVIDIA adapter in Device Manager (only after confirming Intel works). If uninstalling NVIDIA drivers, keep a working Intel driver and have Safe Mode recovery instructions ready.

Clarifications and cautions:

  • Integrated graphics use shared system memory dynamically; they don’t permanently “steal” large amounts of RAM in normal use. Discrete NVIDIA cards have their own VRAM and will still outperform Intel for games and CUDA tasks.
  • Aero needs a vendor WDDM driver — if Windows falls back to the generic driver Aero will be degraded or disabled.
  • Some laptops wire external ports or special features to the discrete GPU or lock switching in BIOS; if problems appear, restore the NVIDIA driver from Safe Mode and use the OEM drivers from Sony for the cleanest behavior.

yes it should ,but it would not be that good .it would just use windows default video drive ,most laptops come with a decitaded video device,soldered to the motherboard ,some /all good gaming laptops have devices that can be removed /changed there would be no intel video driver[having nvideo is considered to be better than having the Intel device ] because its not using intergrated intel device, its using nvida device .what is the exact model of the sone,usually found on the bottom of the laptop
why would you want to disable the nvida device ,just curisuos

Does my laptop graphics( like windows aero) work even If I disable the Nvidia driver.

Quite a number of laptops are coming with Intel integrated video, as well as nVidia video adaptors, and switch between them (if you run Windows 7) seamlessly, depending upon what your video requirements may be. Myself, I disable the Intel video, since it takes up needed RAM resources (the nVidia hardware has its own vRAM). In any case, the nVidia is better than the Intel video hardware, but if you want to use more than 2 displays, then you will need to keep the Intel hardware enabled. As for Aero, I can't say since I disable it as soon as I can - it just gets in my way...
