What should I do when the notebook Win8.1 system unplugs the power cord?

  

1. Right click on the desktop, select the screen resolution, and select Advanced Settings. This is the brush frequency of the computer. Set both to be 60HZ or 50HZ;

2. Adjust the refresh rate of the power supply;

3. Find the power supply in the lower right corner, right click with the mouse, and select the power option; >

3. Find the Change Advanced Power Settings, find Intel(R) Graphics settings and click Expand. If you choose 60HZ in the first step, set the Intel(R) Graphics settings to use the battery and power on to Maximum Performance. If you choose 50HZ in the first step, use the battery and connect the Intel(R) Graphics settings. The power supply is set to Minimum Performance;

After setting the above method, the Win8.1 system will not have a black screen when the power cord is unplugged.
