Depending on the operating system version, PC can be closed as follows:

• Windows XP: Click Start, Turn Off Computer and select the Turn Off, then wait the computer to shut down


• Windows Vista: Click on the logo of the Windows Start menu, then on the right side near those 2 buttons, there is a small arrow oriented to top. Click it, then select Shut Down

There are other 3 ways to close the computer:

• Hibernate


• Stand By


• Suspend

We can activate them from the same menu as for normal closure. In Windows XP to hibernate will press SHIFT when those 3 buttons appear, and would appear the Hibernate button instead of Stand By.

What differs those ways of closing?
Hibernate mode, saves all you will it can find in the computers memory hard drive and after that, the computer will close. At opening will re-read the data from that section, and will continue for where it remained. To write such data is required on the hard-disk space at least equal to the amount of physical memory Windows.

Stand-by mode, will disable only certain portions of the computer such as monitor, hard drives, optical drive.

In suspend mode, the computer will close everything, and what will remain active, is the memory and small piece of motherboard which allows memory data to be kept until you power up the computer back. This mode is the fastest, but do not forget to save all your data in this situation, because as a result of a power failure you will lose everything you had in memory.

How do I use Suspend mode?
Suspend mode is used by Stand By. It's done in the same way, but for the Stand By button to have the function of Suspend mode instead of Stand by, it is necessary to change in the Power Settings from BIOS, the way Stand by works, from normal StandBy in the Suspend to RAM or S3.
