Meaning of Hibernate in Laptop

What is the meaning of Hibernate in Laptop when charge is reduced?

Well when you switch your laptop to hibernate, you are turning your computer off but saving everything you had up last while the computer was on. So when you turn it back on, the laptop will load up all the last work or whatever windows you had open before you enabled hibernate. If you have eco mode on your laptop then you will use less power than normal. In eco mode your monitor will dim and it will use less power than normal. Or you can click on "start", "the control panel", then double click on "power options" to make certain changes to the screen saver and other options to reduce the use of your battery or just to save on power. Like how bright your monitor can be changed to reduce the power used by your battery. I hope this was helpful.
