How to disable integrated graphics card on p150em ?

System is as follows:

windows 7 64 bit
I7 2670 qm i think??
Samsung SSD 500gb
nvidia 675m
8 GB RAM

Did not see an option to in the BIOS so I am asking here [unless I somehow missed it but don't thinkso?]. Thank you

 

As far as remember, the EM series have the panel controlled by the iGPU, so even if the dGPU is used, it still has to go through the iGPU. There is no direct link from the dGPU to the panel, so you can't disable the iGPU, you have to use switchable graphics, Optimus in your case.
The EM series was made for the Intel Ivy 3xxxm CPUs, but may have come with the older Sandy 2xxxm CPUs for a short time. Your system info and BIOS will tell you what you have.

 

That's right. Best you can do is use Nvidia control panel to set it to use the dGPU by default for everything. And yes the first EMs came with Sandy Bridge

 

See I don't have Optimus and anything to download that on the nvidia page is really old. It's the first i've even heard of having to use it for this model.

Basically though I made this thread http://forum.notebookreview.com/thr...ce-cannot-be-ejected-or-removed-error.799997/

It seemed by people in that thread that it was caused by Temperature problems. I've since ruled out that it's NOT temperature related and no one is responding and this is one of few things left I have to try

 

A quick google finds all reviews saying it has optimus... Optimus is simply how the OS handles using either the intel or nvidia to process an application. The intel always handles the output to the internal screen as it is directly connected to it.

 

You can't possibly have used the dGPU without Optimus, it just won't work.

 

I type "Optimus" when I press windows and nothing comes up. Or is it not a program where you can examine things?

 

Optimus is just they name they give it, there is no 'Optimus' program. You just install the standard Intel and Nvidia GPU drivers and then go into the Nvidia control panel, and under 'Manage 3D settings' set it to the card you want the system to use either as everything use that card or go in and set it on a program by program basis

 

and to external displays. All video out is routed to the Intel GPU.

@Aplaudible - You mentioned you thought that your graphics card might be faulty. It kind of sounds like it... Have you/the tech you brought the laptop to flash (update) your video BIOS? And what system BIOS are you running?

 

Are you sure this is true for all laptops? I was sure there were some that had certain video outputs that were only connected to the discrete GPU. Unless those were only the laptops that have the manual switching of the GPU's?

Also I was certain I had laptops where when I ran off an external screen, no matter what I did it was always using the dGPU even though I was just surfing. I fought trying to force everything to run off the iGPU manually but couldn't. I wish I could remember what laptop(s) that was but I remember trying to reduce heat when idling and no matter what the dGPU was in use. When I unplugged the external screen, the problem went away. My conclusion was that the port was directly connected to the dGPU.

 

Not all laptops, no. The EM series, at least those with Optimus: Yes.

 

Sorry for the delay,

@Prostar Computer no we didn't try that I don't think. My BIOS according to dxdiag is "Bios date: 09/06/12 ver 04.06.05"

 

As @Prostar Computer touched on, not true for all laptops. For Clevo models, there's been a handful of different configurations in the past including chassis which routed the dGPU through the iGPU (as mentioned, the "original" Optimus setup) and then generally socket CPU/discrete GPUs which bypass the iGPU.

Though some other manufacturers had MUX switches in the past, G-Sync was the driving factor in Clevo integrating this technology - simply because G-Sync requires a direct connection between the dGPU and the internal LCD panel. This is where you may have seen MSHYBRID be mentioned as an option (in place of Optimus) - you can still run the equivalent of Optimus with HSHYBRID, either the iGPU provides the graphics or when on load the dGPU will route through the iGPU for more power. This maintains the power efficiency and gives longer battery life, but to use G-Sync you have to switch to dGPU mode - which bypasses the iGPU but requires a reboot.

On most of the higher end Clevo chassis the external ports are pernamently connected to the dGPU no matter if you run in MSHYBRID or dGPU/DISCRETE mode. This has lots of advantages, including that VR HMDs require a direct connection to the dGPU. If you see a VR Ready sticker on some Clevo chassis it is specifying this dGPU - HDMI/DP connection, opposed to the official Nvidia VRReady sticker which means that the chassis meets the Nvidia minimum performance recommended specification for VR, as well as dGPU - HDMI/DP ports.

 

No worries. I don't think that's your system BIOS, though.

Quickest/easiest way to check is to load the BIOS setup: Reboot the PC and hold F2. The first screen that shows up should show you your BIOS & KBC/EC firmware versions about halfway down the page.

 

Some of the older ones (think to HD4570 days) could switch on the fly (if you shut down programs, a bit like SLI), the only BIG down side of that was the special drivers needed that in the end never got updated for long.

 

Blimey, that's going back a bit ;-) I think they went EOL in 2009 roundabouts but that's AMD rather than Nvidia. The latter wanted a seemless user experience with Optimus i.e. auto switching without having to "worry" about what the laptop was doind, I think that's the main reason for resistance to MUX switches in Nvidia GPU laptops in the past.
