Sleep and hibernation of Windows 7

the term "sleep" sign each user Vindovs operating systems, regardless of whether it has engaged ever this opportunity or not.And we are not talking about some hidden settings and a standard off the menu called up by pressing "Start".The proposed list of actions is a dream and hibernation (standby in Win XP).Although it is believed that these features are designed primarily for laptop owners, in fact far from it.Moreover, the idea has been so successful that in recent versions of Microsoft Vindovs even introduced innovation - Hybrid sleep-oriented PCs.

Before we look at what sleep and hibernation Windows 7 clarify a curious fact.In the web and then you can find user reviews admiring the latest operating systems Vindovs, according to which the download speed of your computer after upgrading to a new version of the system has grown significantly (indicated 10, 8 or even 6 seconds).Similar data is sometimes referred to, and by the developer.That's just the speed of this fantastic watch, not all users.No cheating, no!Just "accidentally" do not indicate that such loading is performed only if you are using Hibernate Windows 7, and not a standard full power off.

Sleep systems Vindovs is a special way to turn off the computer, allowing for a second to resume work with the same data, which were at the time of "deep sleep."It can be compared with the functions of "Pause" and "Save position" players.Sleep and Hibernate Windows 7, may be involved in the performance of three conditions: the motherboard BIOS supports regimes installed the correct device drivers, operating system "knows" about these functions.To make adjustments in the BIOS should go to the settings (the Del key immediately after switching on) and select the desired status in the parameters of ACPI (S1 - S4):

S1 - power to the processor and memory served, but the executive conveyors suspended.Devices that do not explicitly expose the values ​​of its registers can be disabled;

S2 - the same as the S1, but the CPU is de-energized;

S3 (STR, Suspend-to-RAM, Standby) - one of the most popular, particularly among notebook users.Disables all components except RAM.Because of this, all information stored in it at the time of transition to the standby mode, does not disappear.When the user is able to almost instantly continue your work.Power consumption exceeds 1 watt.The lack of one, but a significant - even when short-term cease-supply all data is lost;

S4 (aka hibernation of Windows 7) - the most reliable mode.All data stored in memory at the time of shutdown, written to the hard disk (Dump).When the operating system reads the information from the file hiberfil.sys.When the low-speed hard drive, and a large amount of installed RAM recovery from S4 may take longer than downloading "from scratch".

There is also a hybrid sleep.There is nothing difficult in it, because the name itself gives a clue.Hybrid mode is a combined S3 and S4.When you turn off this data is not only stored in the RAM modules, but also throws in a dump.If the interval between the switching off and on the power supply is not interrupted, the system operation is resumed by reading the state of the memory cells.If for any reason the data in memory are lost, the system recovers from the dump (just as in the case of S4).

Use Sleep mode as laptops and personal computers.In the absence of problems with the power supply can be recommended to opt for the mode S3.
