Hi there folks!

I am having trouble with my new Fujitsu laptop. I have an onboard GPU (Intel® HD Graphics Family) and a non-onboard NVIDIA GeForce GT 525M GPU. I have Windows 7 Home Premium (Service Pack 1) and the latest drivers for my NVIDIA video card. I also obviously have DirectX 11 installed, since I have Win7.

Now, the problem is that although Windows detects both GPUs, it uses the Intel one (this was true both before installing the latest NVIDIA driver and before that).

I know it's using the Intel one since: 1. If I go to Control Panel->Display->Change display settings->Advanced settings, the Properties window for the Intel GPU pops up; 2. If I go to Intel® Graphics and Media Control Panel, under Options and Support->Information Center, it says "Processor Graphics In Use: Intel® HD Graphics 3000"; and 3. Graphics quality/performance is way too low for the NVIDIA GPU.

I tried disabling the Intel HD thing in Device Manager, but all that happened was that the screen went blank, so I restarted my computer, booted into Safe Mode (the screen wasn't blank there), re-enabled the Intel, and then restarted Windows into normal mode (and obviously I still had the problem with Windows not using the NVIDIA GPU.

Also, if I go into NVIDIA Control Panel (click the system tray icon and click "Customize which programs use the GPU"), under "Manage 3D Settings", if I add a game to the list of "programs to customize" (in the Program Settings tab) and then click Apply, the game still behaves as if it was using the Intel on-board GPU (as in, nothing changes in terms of quality and/or performance, regardless of the graphics settings). Also, in the Program Settings tab, under "2. Select the preferred graphics processor for this program", the selected setting is "Use global setting (Auto-select: NVIDIA GPU)" and it doesn't allow me to change that (the drop-down list is greyed out).

So could you guys please help me solve this little issue? Pretty please?

Hello and welcome to Bleeping Computer.

Have you tried booting into your computer's BIOS setup utility and change the settings for your on-board and add-on card?

I do not know what motherboard you have since you did not include that information, so I can not say exactly how your BIOS is designed for menu options, but you might want to do some investigating in your BIOS to make those changes stick once your operating system takes over the boot process.

Bruce.

I tried going into the BIOS setup utility, but I was unable to find anything related to switching GPUs, or even related to GPUs at all. So maybe I'm not looking in the right place or something? Could you please tell me where in the BIOS setup I'm supposed to find a way of doing this?

I used CPU-Z to find out what my motherboard is. Here is the screenshot: Attached File  Motherboard.png   27.44KB   6 downloads.

It seems like your laptop is an LifeBook AH531/GFO

Please check the specs on the page below, is this your computer?

Notice: The image on this page below shows your LifeBook laptop in between two halves of a computer tower, so don't that image of the computer tower fool you.

Thanks in advance.

This is a direct download of your owners manual.
