You deploy several tablet PCs that run Windows 10 Enterprise. You need to minimize power usage
when the user presses the sleep button. What should you do?

A.
In Power Options, configure the sleep button setting to Sleep.

B.
In Power Options, configure the sleep button setting to Hibernate.

C.
Configure the active power plan to set the system cooling policy to passive.

D.
Disable the C-State control in the computer’s BIOS.

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.
