win8.1 system Notebook Set charging threshold method for battery. Now notebook computer has become an indispensable part of life and office, go out will bring notebook office, so the power problem has always been the concern of everyone, every time the notebook win8.1 system forget to recharge, resulting in the notebook automatic shutdown. To avoid this happening notebook Win8.1 system can set charging threshold for the battery, for example, the charging threshold is set to 20%~100%, then the battery will start charging when the electricity is less than 20%, charge to 100% when it will automatically stop charging, so you will not forget to recharge. So how does the laptop win8.1 system set a charging threshold for the battery? Let's take a look at the specific setup method.
The method is as follows:
First, the driver software preparation
Download the latest power management drivers and Lenovo Setting, which can be updated via system update or downloaded separately from the website;
Power Management Drive: The official website to download;
Lenovo Settings: App Store downloads;
Second, change the registry (hint: Modify the registry is risky, please back up the data in advance and careful operation under the guidance of professionals.) )
1, press the WIN+R key combination to open the running window, enter regedit,
Enter the registry and expand to the following location (64-bit system)
Hkey_local_machinesoftwarewow6432nodelenovopwrmgrvdata
(32-bit system can find the following locations)
Hkey_local_machinesoftwarelenovopwrmgrvdata
2, find the following key values to make changes (a total of four key values need to be modified).
Charge start control changes to 1 open charge threshold controls;
Charge Start percentage change to the charge threshold value you want to set (note to decimal)
Charge stop control changes to 1 open stop charge threshold controls;
Charge stop percentage, change to the stop charge threshold value you want to set (note to decimal)
The example below shows a 90% start charge, and 100% stops charging.
3, restart the computer to make the settings effective. Note that because this setting is implemented by changing the registry, it is effective to enter the system, noting that the Shutdown state plug adapter will fail (the phenomenon is the same as the previous Power Manager, and the plug adapter will be reset in the shutdown state).
The tutorial content is the notebook win8.1 system to set the battery charging threshold method, is not very simple, after setting, we will not forget to recharge the laptop.
