Modern laptop models are sold with video cards. Some are weaker, others are stronger. But a situation may arise when it is necessary to turn off the video card. This can be done in different ways, and each case requires a different approach. The easiest way to do this is through the BIOS. To do this, you need to do certain step-by-step operations.

Personal computer, Tools & Options program
Instructions
Step 1
Press the "Del" or "F2" key while the laptop restarts. BIOS will open. Find a section such as "Integrated Peripherals" in the menu and select "Integrated Video" or "Integrated Peripherals". Set the parameters to "Disable" or "Off". You can also disable it in BIOS in the following way. Go to the "Advenced Chipset Features" section. Find the item "Boot Graphics Priori". Replace "PCI" with "PCIIGD".
Step 2
You can try other methods as well. In Windows, uninstall the driver for the video card. Reboot your computer. The video card should then shut down completely. Go to your laptop BIOS. Find the "Integrated …" section. Open the "Init Display First" options. Set it to “PEx” instead of “Onboard VGA”. Save these settings and reboot the laptop again. Go to BIOS. Find the "Advanced" tab. Next, look for the "chipset" parameter. Click on the Primary Video Controller tab. Disable “GFXO-GPP-IGFX-PCI” or “IGFX-GFXO-GPP-PC”. Then press “F10” to save the settings.
Step 3
Start Registry Editor. Go to "Win + R" and select the "regedit" command. Click "Ok". Open “HKEY_LOCAL_MACHINESOFTWAREATITechnologiesCDS000Memory”. Change the value of "hypermemory" to "0". If for some reason there is no such branch, create it manually. Download and install the “Tools & Options” utility. On the Internet, this utility is distributed completely free of charge. There will be no problems with the installation. Run it. Go to the "General Options" parameter, and select the "Advanced" value. Uncheck the box next to Enable ATT Shared Memory.
Step 4
If your operating system is Windows7, go to the "Control Panel". Select "Device Manager". Next, go to the "Video adapter" tab and do all the necessary disconnections there.
