Lenovo dual-graphics card exclusive display solution under Win8

Shortly after Win8 came out, the comrades who liked to play early adopters installed Win8. After all, after how many years later Win8 will eventually be replaced, like Windows 7's XP elimination, although there are still many people in XP. Of course, I must have installed Win8 (32-bit Enterprise Edition). The new system has many compatibility problems. framework 3.5 is not suitable. I have already made a detailed introduction in my blog some time ago. Here I will only introduce the solution for disabling independent graphics cards in Win8.
After installing the system, I believe that everyone will check whether the driver of their computer is installed and whether it works properly after the installation. Otherwise, the computer cannot work with the best effect, and I am no exception, after I installed Win8, I found that Win8 had a lot of built-in drivers. Even the NIC and wireless Nic drivers were installed, but my computer was always very stuck. Check the configuration of my computer and it should be perfectly supported, so the Windows + X-> Device Manager found the problem. My amd graphics card driver had an exclamation point on it, so I re-installed it. The exclamation point was gone, but I restarted the exclamation point and came out again, the computer is also super-card, and later I learned that Win8 will automatically apply for a visa to the driver, the graphics card Driver Visa failed, so the exclamation point is coming, the computer only works with integrated graphics cards, of course, very stuck, after painstaking efforts, the problem was finally solved. The specific solution process is as follows.
Lenovo computer users will find a great advantage, that is, the after-sales service is very considerate. If the driver is abnormal, they can go to Lenovo's official website to check their own machines. Then Lenovo's official website will provide the best driver download link, we recommend that users with dual-graphics cards download the drivers from the official website and install them. During the installation process, there will be multiple black screen flashes, so don't worry about this. Of course, the above practice cannot solve the problem. You have to cancel Microsoft's automatic VISA Function and restart it later. The specific steps for canceling a visa are as follows:
1. Move the mouse to the lower-right corner, find the settings, Click Show, and then click Change computer settings.

2. Find the general options, find the last advanced boot item, and click restart now. The screen will be black and you don't have to worry about it. There will be a lot of options, so you won't be able to do that. Tell you which option to choose.

3. Select "difficult options"> restart> 7. The problem is fixed. You can install the driver on Baidu. If the driver is not installed, you are advised to install the driver under the guidance of experts.
