I Don't Understand This Thing

Question

When you click on the S.H.E. button, three clickable symbols emerge: zZ, a feather, and an N in a circle. What exactly does each of these things do? Also, when you click on the lower button, a drop-down item emerges with a clickable wrench. What exactly does it do?

Answer 1

The application is used to manage the power consumption in your computer. The symbols you have mentioned are assigned to different power plans (sleep, light, normal). The wrench button is used to customize various aspects of the application.
