Graphics Switching in Windows 7 - Macbook Pro 2011

Hi, I have a the same problem in activating Intel HD 3000 on my Macbook pro,can you write some solution (step by step) how you done this. I need to use just only intel HD (Quick sync technology ) If I'm right , you installed win7 on Efi mod. thanks a lot.

Anybody managed to do something with this? Or are there any update from Apple? I need again to install Win8 but do not want to lose time if Apple still wants to overheat the laptop.😟

The overheating issue is not an Apple issue, it is a Windows OS issue. CSM-BIOS exposes the correct GPU due to lack of GPU switching in Windows (unavailable up to W8.1). W10 may address it.

For overheating issues, go to Power plan-> Advanced power setting -> Processor power management -> Minimum processor state and set it for around 5%, as default should be 100%. If it shows 5%, still put in 5% and click Apply and test.

Ok. I wasn't correct in my message. Of course the main disappointing thing is that the battery life is 3-4H only as Windows uses NVidia graphics only.

And I think it should be Apple who will fix the issue with an updated boot camp drivers!

The Battery issue is related to individual usage patterns as well. Please see OS X Yosemite: Manage your portable computer’s battery for a general discussion.

My battery is ok in OSX but it lives several hours when I'm working in Win (again due to the GPU in use). That was mentioned many times in this topic.

In OSX, with GPU switching, when an external display or certain processes are not involved, it will switch to the Integrated GPUs. With Windows, there are several issues that Windows cannot handle (W10 may support and handle these).

1. On Macs prior to Late 2013, CSM-BIOS exposes only the discrete GPU, which takes up more battery. UEFI Macs can be forced to use the internal GPU by uninstalling the discrete GPU drivers.

2. Windows 7 and 8 lack support for GPU switching.

3. Wireless networking consumes higher battery on Windows.

4. BT (without BT-LE support) consumes more battery.

Unless Windows is your primary OS, when on Battery, I suggest using OS X.

Has anybody tried to install Win 10? Did it help to solve the issue with GPUs switch?

Nope. It's not something Microsoft can fix as far as I can tell, they already support many laptops with switchable GPU's no problem. It's been that way since Win 7 as on my previous laptop.

It's appears that Apple has disabled the Intel Graphics somehow, so that it's not detected by Windows. This is very unfortunate as the AMD GPU kills my battery in 3-4 hours.

I don't see how this a Windows OS issue, switchable graphics has been available since at least Windows 7.

Only on Late 2013 or later models. The drivers for GPUs are provided by Apple. Switchable GPUs require EFI Windows on a GPT. CSM-BIOS exposes only the discrete GPU.

Is anybody managed this issue ???

I have the same probem... Macbook Pro Mid 2014 ... Win7 installed via Boot Camp works fine but only on Intel graphic card... how the **** can I switch on my GF 750M ????????

Cheeeers

Since your Mac is UEFI, you can install W7 using EFI Boot. Be aware that W7 EFI is not very stable and has sleep/hibernate and power management issues. EFI should expose both GPUs and then you can use whichever one you prefer.

Well... I saw how "stable" is EFI Boot... Actually it makes Your computer almost imposible to work on :///

Since 2010-2011still isn't really there any solution for this ????

Regards

The only hope that Apple support will see this topic and cooperate with Microsoft on this...
