Current Windows operating systems (OS) have provided a power slider function on
notebook (NB) systems so that a user can change their power setting immediately, without
clicking into the power options for further power plan setting. However, as a user, I found I
cannot detect that any change is happening when I change the bar on the power slider
In current OS design there are four levels in DC mode from which a user may select: 1.
Best Performance, 2. Better Performance, 3. Better Battery, and 4. Best Battery. But in fact,
options 1, 2, and 3 look similar and only with option 4 the backlight appears a little darker.
Therefore, a user may only feel that power settings may have changed when selecting
option 4 (Best Battery).
