This problem has been bothering me for a long time, it will be time to shut down or hibernate. Access to relevant information is said to occur after Win10 updated 1803 version.
Multiple versions of the solutions appear online:
1. Modify the registry settings, and power supply
Using this method did not resolve it
2. reinstall the system or restore Windows (new Lenovo has a small reduction function, the left hand side there is a small hole with a needle card or other elongated tool poke)
Because after reloading a lot of things we need to be reinstalled to give up the method
3. Upgrade BIOS (I pro-test to solve)
