HP DV6 7002TX Why can t you switch to a 650 graphics card all the time?

1. According to the information you provided, the graphics card specification of your machine is an NVIDIA GeForce GT 650M graphics card.

2. As for the operation mechanism of third-party software, we do not have relevant information and cannot guarantee its accuracy. If you have a question, it is recommended that you go to the Device Manager to view: it is recommended to right-click the computer icon - Management - Device Manager, and under the display adaptation, please see if the display is normal.

If it is not normal, it should be caused by the graphics card driver is not installed properly or the system is faulty.

4. Before installing the graphics card driver, please uninstall the previous graphics card driver in Device Manager, and then install the latest graphics card driver on the HP official website. Right-click on the blank space of your desktop and select "--Exchangeable Graphics" --- Power Supply in ATI Catalyst Control Center. The high-performance mode is to use a discrete graphics card; The power-saving mode is the use of integrated graphics.

5. If you still can't switch between dual graphics cards, it may be caused by your system problems, you can try to reinstall the system with the pure version of the system installation CD, and then install the corresponding graphics card driver test. The pure version of the system is different from the ghost version and the optimized system version, it is not optimized, and you install it step by step according to the system installation prompts when you install it, and you need to install the driver system yourself after installation.

If you are using a pre-installed system, you can back up your personal data and resume system testing.

You can now force the switch manually.

1. Different notebook models, graphics card switching methods are also different, if you want to change this notebook to graphics card switching mode, you need to refresh the version BIOS. In addition, this notebook can be installed with Win7 32-bit system or 64-bit system.

If you have important data in your computer, it is recommended that you back up your data first, please consider carefully before doing so! Below I will tell you about the precautions for flashing the BIOS:

1) Connect the external power adapter and the battery, so that the computer is in a stable state of power supply.

2) During the refresh process, do not run other programs in the background, such as anti-virus software.

3) During the refresh process, do not interrupt abnormally.

2. The type of graphics card you use to run the software program is related to the settings in your graphics card switching interface (the high-performance mode is to use a discrete graphics card, and the power-saving mode is to use an integrated graphics card), and it is also related to the application itself. The machine has not been tested on this 360 software before leaving the factory, and the accuracy and stability of the test results cannot be guaranteed.

If you're using DirectX 9, it will run as an integrated graphics card, even if you're setting up a discrete graphics card. If you are worried that the discrete graphics card is not being used when the program is running, it is recommended that you open the GPU-Z software while running the program and see if the usage of the discrete graphics card is higher than that of the integrated graphics card.

I hope the above reply can be helpful to you.

1. This situation is likely to be caused by a problem with the graphics card driver, is there any error message on the screen when you can't install the driver?
