Explanation:
We can minimize power usage on the tablet PCs by configuring them to use Hibernation mode. A computer in hibernation mode uses no power at all.
Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won't use your laptop for an extended period and won't have an opportunity to charge the battery during that time.
Incorrect Answers:
A: Sleep is a power-saving state that allows a computer to quickly resume full-power operation. A sleeping computer draws a small amount of power whereas a hibernating computer uses no power.
C: A passive cooling policy slows down the processor before speeding up the processor's cooling fan to conserve power. However, this will still use more power than a hibernating tablet.
D: C-States are different modes of CPU clock speed used to conserve power when processors are idle.
Disabling C-State control disables the ability to reduce the power consumption of the computer.
