Hibernation is a power-saving state that is primarily designed for portable computers.

Sleep typically saves work and settings in memory and consumes a small amount of power, while hibernation saves open documents and programs to your hard disk, and then shuts down your computer.

1, hibernation is the memory of the data in the hard disk, and then power off, you can disconnect the power, the next time you start to call the data on the hard drive, back to the state before the shutdown, start fast.

But unlike a real reboot, it just restores the system before it was last dormant.

Characteristics:

The computer writes the current content to the hard disk, how much memory is written to the system disk, and then the computer completely shuts down the power. At this point the fan stops turning, just like the usual shutdown.

Disadvantage: The system disk to occupy memory capacity space.

Wake-up mode: Press power key to boot.

2, sleep is to keep the data in memory, at the same time to the low power supply of memory, can not disconnect the power supply, a disconnection of the power information will be lost, the next wake-up directly read in memory data.

When the computer is not used, it enters the low-power mode, which can reduce the energy consumption to less than half.

Features: Hard drive off monitor off processor keeps very low power all fans work as usual.

Disadvantage: Can not power off a power loss data is lost, can not be restored

Wake-up mode: The system can be restored to its original state within one or two seconds as long as the mouse or keyboard is clicked lightly.

Apply to: Leave time is not long, come back can restore the system state.
