Hey, do you know there are ways to save the battery power for long duration. You need not have to shutdown down the computer every time, when you wish to go off from it for a mean time. There are options of sleep and hibernate which fulfill this criteria.
Sleep is a power saving mode that allows a computer to quickly resume all the applications which were earlier running in your system. It s just like pausing a DVD player and playing again when you wish to do so.
Hibernate is also a power saving mode, designed especially for laptops or portable computers. While sleep draws small amount of power by keeping open documents and applications into the memory, hibernate do so by keeping them in hard disk and turns off your computer. It takes less amount of power in comparison with all other power saving modes available in the computer system.
