ACPI Suspend Mode

Option name:

ACPI Suspend Mode

Possible values of an option:

[S1 State], [S3 State]

The option description:

The option allows to specify, what of modes will be used at passage in power savings state: [S1 State] or [S3 State]. If your motherboard and the power unit are compatible to the second mode, select it, as more economic.

Is short we stop on these modes. The majority of the computers supporting specifications ACPI, two modes of power savings allow to use: S1 (POS) and S3 (STR). In the first (it is decrypted as Power on Suspend) a supply is disconnected from a hard disk, some expansion cards, plus, the monitor is extinguished. All remaining components (the processor, a random access memory, a chipset…) Work in a regular mode, passage to the under frequencies is possible only. Thanks to it awakening happens very quickly. The second mode (abbreviation from Suspend to RAM) is characterized much by smaller power consumption. Before passage in it all information on a state of various components is saved in a random access memory then all remaining devices are disconnected, there is only a supply on duty. To pay off for it it is necessary longer awakening of the computer. Is still Hibernate or Suspend to Disk, but it does not concern power savings modes. At its usage the information on a state of various components "is dropped" on a hard disk then there is a normal switch-off of a supply.

That mode Suspend to RAM (as, however, and Suspend to Disk) functioned without failures, accurate interaction of all drivers of the components installed in system is necessary. In the presence of "the curve" driver the computer can not wake up generally or after an output from a doze mode to work with errors. In this case it is necessary to return to less exacting in this plan Power on Suspend.

Mode Suspend to RAM superimposes certain restrictions on the power unit: the current given on circuit Standby (+5V SB), should be not less than 800 mA (it is recommended 1). To the modern models of claims in this plan is not present — all of them are compatible to mode Suspend to RAM, problems can arise only with old computers.
