My system:
Toshiba L850-1C9
8 GB DDR3 RAM
i7-3610QM (HD 4000 ?)
AMD 7670M 2GB

As the title says, my iGPU is maybe not workin. It is not listed in my Device Manager and GPU-Z. And my graphics card is getting really hot, about 50 - 60 Degrees, even if I`m just writing.

I tried to install the newest Toshiba Intel HD 4000 Drivers, but the setup said, that my system does not meet the minimum requriments to install it.

I also tried to go into the BIOS, but it had not the option to turn on Dynamic Graphic switch or something like that.

did you deinstall your radeon drivers first? Its not possible to use iGPU and dGPU at the same time.

1. Use ATI Catalyst to adjust
2. Set Windows Power management to anything BUT NOT *High Performance* and NOT *Gaming* , adjust power settings for battery usage or power outlet usage as you see fit.
3.

I’d like to know the ‘Catalyst Control Center’ version installed on your computer. Please follow the steps mentioned below to find out the version.
Open ‘Catalyst Control Center’ by clicking the Start button . In the search box, type ‘Catalyst Control Center’, and then, in the list of results, click ‘Catalyst Control Center’.
Click on ‘Information’ tab in the left.
Click on ‘software’ under ‘Information’ tab.
Let me know the catalyst version on your computer.

Also, I’d like to know if you see ‘Switchable Graphics’ under ‘Power’ section in the ‘Catalyst Control Center’.

If the HD 4000 is not showing up at all, you need to do this:

I’d suggest you uninstall the ‘catalyst control center’ & ‘Intel HD 4000’ from Programs and features under the control panel.

Then reinstall the ‘Intel HD 4000’ first and then reinstall ‘AMD RADEON HD 7670M’ drivers & ‘catalyst control center’ in sequence.

Wait, so its possible to simply choose between igpu and dgpu with Catalyst? I always thought the iGPU is only activated when no graphicscard is installed.

Yes it is possible to choose which GPU is being used in the power management section of Catalyst which affects all programs, you can also choose which GPU is used in the per program options in Catalyst, you can also choose which GPU is used (globally again) in the Windows Power management options,

There was no Switchable Graphics option in CCC , and I had version 13.3.

I did uninstall, the AMD Software with Control Center, Devices Manager and Driver Sweeper and restarted my laptop. Now I was running with Microsoft Basic Graphic Driver.

Next i downloaded the Intel hd Display Driver for my Toshiba Laptop: display-en-20121026072519

The result was, that I was able the extract it, but it not started the installer, as mentioned in the setup.
As I opened the file directory, and started "tinstall" it said: "Your system does not meet the minimal requirements."

Suddenly my screen got dark for a couple of seconds, and at some reason my 7670 was activated again.


I wonder if I have a iGPU ??
The i7-3610 should have a hd 4000, or not?

Yes you'll have the HD 4000 built onto that i7 chip.

With mobile chipsets they normally allow load-based switching or even application based switching. It may be part of Windows power management or ATI, I remember my laptop had both i7 + ATI GPU (6660 maybe?) and I had a switch to turn it on and off, on that laptop (physical switch), maybe theres some application from toshiba to do the same?


Also with drivers, try direct from Intel

Another thing to try:
Download GPU-Z
GPU-Z Video card GPU Information Utility

Then run it and it will tell you what graphics is enabled. It may just be that your GPU is in a hot part of the package of your laptop, and without it being powered and fanned, it'll keep warm.
Otherwise, the OEM (Toshiba) may not have implemented a switch, for cost saving reasons or something else? Not totally sure about that, maybe a google search will discover the answer

When I installed the driver from Intel, the setup failed again, with the message mentioned before.

GPU-Z recognizes only my 7670.

I can`t find anything helpful with Google search

Ok, I found the reason for this.
Toshiba has disabled for some reason the hd 4000 on all L850 Laptops, so I cant use it.
So I have to deal with a shorter battery life time.
