System sleep, sleep, shut down and use the difference between

 I have carefully read this part of the help, it should be said that sleep is a good improvement.
sleep thinking is quite clear:
XP off the case in the past can be divided into:
1, off: This is very simple not to say
2, Standby: standby is off hard disk and displays, only to the power of memory, so you can quickly wake up, but need the power mode s3 motherboard supports. At the same time can not turn off the external power supply, for example, unplug the AC plug, otherwise it will cause data loss.
3, sleep: Sleep is the memory data is written to disk, and then shut down. After wake-up data from the hard drive into memory to restore the previous work.

vista in the sleep and standby brings together, called sleep, also called hybrid sleep.
hybrid sleep, I guess it is 2 parallel to the work.
while the data remains in memory while the data is written to disk. Then enter standby mode, maintaining a very low power consumption.
When the boot time, you can quickly resume from standby.
even unplug the AC power during standby, because there sleep on the hard disk data, so you can recover from the hard disk. Very clever.
vista is not recommended to shut down a few hours each time, so it's the power button into a sleep.
switch very fast, are just a few seconds.
on vista but my motherboard support is not very good, short sleep, not die, but for a long time to not wake up, non-restart is not; sometimes he can not sleep.

What is sleep?
is an energy-saving sleep state. Sleep to save all open documents and programs, when you want to start working again when the computer can quickly restore full power operation (typically within a few seconds.) The computer to sleep like a DVD player pause: the computer immediately stop ongoing operations, and ready to return to work state you want to start again.
To enable the computer to sleep, click the By pressing the sleep button or close the lid on the mobile PC allows the computer to sleep.

What is sleep?
is an energy saving sleep state, this state can open documents and programs saved to the hard disk, and then turn off your computer. When you are ready to use the computer again, it could be a few seconds of waking up from hibernation, and then restore all the saved open programs and documents. Windows uses all the energy state, hibernation uses the least power.
and sleep, mobile PC, sleep in the open documents and save the program does not require any power supply. Because a small amount of electricity needed to sleep, Windows automatically after sleep in a long time the mobile PC to sleep to help save battery power.
because hibernation on the mobile PC does not require any power to save open documents and programs, so Windows to achieve a very low level in the battery automatically when the mobile PC into hibernation.

for mobile PC, if you know there will be a long time do not use it, and in that time not to charge the battery, you should use the hibernate feature.

system sleep, sleep, shut down the differences and use
Vista shutdown option in the system are: switch user, log off, lock, restart, sleep, sleep, shut down the seven options. Here are some sleep, sleep, shut down the differences and use.
sleep (equivalent to Windows XP operating system inside the stand): Windows to the current memory things are still stored in the memory, hard disk turn off, display off, the processor to maintain very low power, all fans work as usual. Just click the mouse or keyboard, the system can be restored within a second or two to their original state. Leave time is not generally a long time, but also eager to restore just the data, may wish to sleep it. Note: This process can not power off, or they will not be restored)
Sleep: The computer writes the current contents of the hard disk, memory, how much disk space to write the system. And then the computer completely off the power. Then the fan stopped turning, it is no different, and the usual off. Need to wake up when you press the power button as long as you boot, you can completely restore the original state, very fast. Drawback is the system disk space to be occupied by memory capacity. 1G RAM or above is not recommended. Sleep is for long leave or switch too slow a friend! (This process can be off)
off: Theoretically, hibernation and shutdown the computer in the ordinary man, no different. The only difference is that sleep can remain dormant and then boot the system state before, but the shutdown can not.
