Method of setting charging threshold for WIN8 system or Win8.1 system

WIN8 system or Win8.1 system to set the charging threshold method. Lenovo Notebook is the first choice for many small partners, there are also some special features, such as in WIN8 or Win8.1 system can set the battery charge threshold, the charging threshold set to 20% to 100%, which means that the electricity will be less than 20% of their own charge, to 100% will stop charging. Here is a small set for everyone to carefully explain the WIN8 system or Win8.1 system setting the charging threshold 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 Start Percentage

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)

Charge Stop Percentage

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 above is Lenovo notebook win8/win8.1 system set up the charging threshold method step, the charging threshold is actually a battery maintenance mode, can reduce battery charge times, improve battery life.
