What’s the difference between sleep, hibernate, and hybrid sleep?
Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player–the computer immediately stops what it’s doing and is ready to start again when you want to resume working.
Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and set¬tings in memory and draws a small amount of power, hibernation puts your open documents and pro¬grams on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hi¬bernation 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.
Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hi- bernate–it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.

Disable Wake Timers
If you find your Windows computer waking from sleep for no apparent reason, your computer is either be¬ing woken up by a hardware device such as your mouse — or scheduled task set to wake your com- puter.

Starting with Windows 8, a fast startup mode is available to start a computer in less time than is typically required for a traditional, cold startup. A fast startup is a hybrid combination of a cold startup and a wake- from-hibernation startup.

Another similarly missing power option (apparently) is Hibernate, which, although not readily visible, is still a part of the operating system, and you just have to enable it.
