How to set the charging threshold under Win8/Win8.1 system?

Lenovo notebook Win8 and Win8.1 system can set the charging threshold for the battery, for example, the charging threshold is set to 20%~100%, then the battery will start charging when the battery is lower than 20%, charge to 100% The charging will stop automatically. So how should the Win8/Win8.1 system set the charging threshold? Let's take a look at the setup method.

The method is as follows:

First, the driver software preparation

Download the latest power management driver and Lenovo Setting, can be updated by system update, or downloaded to the website alone;

Power management driver: Think official website download;
