1. First check whether the notebook is in sleep or hibernation state. When the notebook is in sleep or hibernation state, and then the notebook is in a suspended black screen state, it will be mistaken for a black screen. So I want to check whether it is in these two states. The solution is: right-click on a blank space on the desktop, bring up the drop-down menu, and select "Personalize". In the lower right corner, select Screen Saver. The screensaver settings tab pops up and enter the power settings in Power Management. In the left menu bar of Power Settings, click "Change computer sleep time." After entering the settings, change all subsequent times to "Never", and then click "Save Changes".

2. After turning on the computer and the brand of the computer disappears, press F8, then press Enter twice. In order, enter safe mode and click the "Advanced Startup" option. Configure it correctly for the last time, and then follow the previous steps. Method Press Enter.

3. Enable "360 Security Guard", find "Trojan Killer" - "360 System First Aid Kit", and repair the system. Then fix everything.

When the laptop turns on and the screen goes black, first check whether the laptop is in sleep or hibernation state to see if it can be solved. If it cannot be solved, you can use 360 ??Security Guard and set the "Advanced Startup" option to repair and check the repair results.
