Using the Easy Battery Manager power options
To use the Easy Battery Manager power options after reinstalling Windows, you
have to install the Easy Battery Manager manually using the system software media.
Since power options in the Easy Battery Manager aim at maximizing the battery
usage time, programs requiring high performance may slow down when using the
battery.
In this case, it is recommended connecting the AC adapter or selecting Power Saver.
