Windows 8 is the newest offering from the software giant Microsoft. Having aimed a total improvement on all aspects in the Windows series of operating systems, Microsoft also ensured that the power saving features too, get an effective makeover that makes Windows 8 an attractive option as far as power consumption reduction is concerned.
Windows 7 and XP had introduced the users to the highly useful and popular modes of Sleep and Hibernate. These features ensured power saving on the user’s part. Sleep, for instance, saves your program settings and data in the current memory, i.e RAM, and puts your computer in a low power consumption state. Hibernate saves your documents, freezes your programs at their current state and switches off the computer. The next time you switch it on, you will find your program as you had left them. Though, the memory used in this case is the hard drive.
Win 8 introduces another mode in this series as the ‘Hybrid Sleep’. As the name suggests, this feature brings the best of both for the user.It saves your documents, freezes your programs in their current status and then uses both the hard drive and the RAM to save them. It then switches the computer in a low power consumption state. The saved data on the hard drive ensures that even if a power cut takes place, your data will not be lost as the computer retrieves the data from the hard drive. There are two ways to get ‘Hybrid Sleep’ turned on:-
(i) Once you are on the start screen, go to the top right hand corner of the screen and open the charms bar.
(ii) Once inside the charms bar, enter Power in the search option and hit enter. The results are displayed.
