For the past years UPS have been used in computer centers and critical business applications.
But the cost of UPS has come down over the years so that UPS can also be used for personal computers too. UPS is a battery backup; it saves power and gives it back when there is a power failure. During power failure you can’t continue working on your computer. If you use UPS, it will give enough time to save the work that you’ve already started.
If you have unsaved data during power failure, you can change your ‘Power Option’ settings to ensure that your computer will go into ‘Hibernate mode’ before the battery backup power is gone. Once a computer enters Hibernate mode, it takes all of the data that is in memory and stores it on your hard drive. Just Follow the below steps to change your system settings.
