You have a business customer who must attend numerous meetings each day and who uses her laptop to take notes during each meeting. She carries her laptop from meeting to meeting and needs to have the computer start up immediately upon arrival at each meeting. What power setting should she use?

A. Standby

B. Hibernate

C. Log off

D. Leave the laptop up and running

Solution

not c) because If you regularly use a laptop, shutting down is extremely inconvenient. Before you shut down, you need to save your work. The next time you go to boot your computer, you’ll have to sit through the boot-up process, manually relaunch all the programs you were using, and reopen all the documents you were editing.

not d) because leaving the laptop up running makes the laptop consume more power

Standby or sleep mode and hibernate, on the other hand, preserve your session. When you’re done using your computer, you can just close your laptop’s lid (or, on a desktop, choose the Sleep or Hibernate option). You don’t have to worry about closing your programs and saving your documents.

Sleep puts your computer into a very low-power mode, and saves its current state in its RAM. Your computer continues drawing a small amount of power to keep that RAM powered on. When you turn on your computer, it can immediately resume from where it left off in just a second or two.

Hibernate, on the other hand, saves your computer’s state to the hard drive, and shuts down completely. Your computer won’t draw any additional power, like it does with sleep. When you turn your computer back on, it will load the data from the disk into RAM and resume from where it left off. You’ll go right back to where you were with all your programs and documents open. It’ll take a bit longer to resume, but it won’t take as long as booting up if you had shut down your computer. How long it takes depends on the speed of your hard drive–if you have a speedy solid-state drive, it should be pretty quick.

here among standdby and hibernate modes ,standby mode is more convienent than hibernate when time is considered to be prominent issue in this case.
