Nvidia optimus disabled for laptops
The new Alienware M17x R.3 is a phenomenal new notebook which has several key "firsts". Some aspects of this system can be confusing, so here's the scoop:
Is this the first 3D Vision notebook offered by Alienware?
Yes, the M17 R.3 is the first Alienware notebook to feature a 120Hz 3D Vision panel.
Does the M17x R.3 support NVIDIA Optimus Technology?
Yes, the M17x R.3 features Optimus technology when a GeForce GTX 460M is chosen without 3D Vision.
I've never seen a GeForce GTX notebook GPU using Optimus technology on a notebook before!
Technically, all of NVIDIA's current notebook GPUs support Optimus technology. However, the choice to implement Optimus technology is up tot he vendor. The Alienware M17x R.3 is the first notebook to feature a GeForce GTX GPU and have Optimus technology implemented.
Why can't I use Optimus technology with 3D Vision?
One of the key aspects of NVIDIA's Optimus technology is that the LVDS display is routed directly to the IGP. This is due to the fact that Optimus always uses the IGP's display controller. When Optimus turns the dGPU is off (100% electrically off, 0W), the IGP is 100% on and enabled. Once Optimus enables the dGPU, every part of the IGP besides the display controller is either shut down or sent to the lowest power state. In each case, the IGP display controller is always used to send to the LCD.
With 3D Vision, the 120Hz 3D LCD needs to be attached directly to the GPU and cannot be routed through the IGP's display controller.
Can I just disable the IGP and run the GPU 100% of the time?
Optimus leverages the IGP and GPU to provide the best performance along with the longest battery life possible. If for some reason you didn't want to reap the benefits of the additional battery life, you cannot disable Optimus by disabling the Intel IGP in the Windows Control Panel. Even when the GPU is being used, Optimus uses the display controller portion of the IGP to render to the system's LVDS panel and the remainder of the IGP remains off. As a result, the IGP can never be fully disabled as you'd have no output to the screen.
(the display is routed to the IGP and literally isn't connected to the GPU)
Fortunately, you have the ability to customize nearly every aspect of Optimus within the NVIDIA Control Panel. Here, you can enable the ability to right-click on an application's .exe and choose whether you want it to run on the IGP or GPU. In addition, you can modify existing Optimus application profiles and create new profiles to force them to run on the IGP or GPU. You can view a YouTube video I created here which outlines how to enable and use this feature (along with the other Optimus features listed within the NVIDIA Control Panel).
USB Universal Serial Bus (USB) is a standard to establish communication between a computer and different devices. USB allows high speed connection of peripherals to a computer. Using USB, you can connect devices like mice, keyboards, printers, external drives, digital cameras, mobile phones, and so on. USB also supports Plug-and-Play installation and hot swapping.

The TCP/IP model uses four layers that logically span the equivalent of the top six layers of the OSI reference model; this is shown in Figure. (The physical layer is not covered by the TCP/IP model because the data link layer is considered the point at which the interface occurs between the TCP/IP stack and the underlying networking hardware.) The following are the TCP/IP model layers, starting from the bottom. Network Interface Layer As its name suggests, this layer represents the place where the actual TCP/IP protocols running at higher layers interface to the local network. This layer is somewhat “controversial” in that some people don't even consider it a “legitimate” part of TCP/IP. This is usually because none of the core IP protocols run at this layer. Despite this, the network interface layer is part of the architecture. It is equivalent to the data link layer (layer two) in the OSI Reference Model and is also sometimes called the link layer.
