Installation Guide for Suspend to RAM J-1
Appendix J. Installation Guide for Suspend to RAM
Suspend To RAM (STR) is a cost-effective, optimal implementation of the ACPI 1.0 specification. The
ACPI specification defines the S3 sleep state, in which all system context is lost except system memory.
CPU, cache, and chip set context are lost in this state. Hardware maintains memory context and restores
some CPU and L2 configuration context.
The STR function enables a PC to achieve the S3 state during idle periods, then quick “wake up” and
retrieve the last “state” of the system before it went to sleep. When idle, STR-enabled systems consume
only a small fraction of the power used for full operation. Instead of shutting down the system to save
power when not in use and then having to reboot later, users can let the STR function take over and not
have to worry about using power to run all the electronics, fans and disks. When needed, a PC with STR
function can restore all applications and features to an operational state within a few seconds.
The following description will tell you how to install the STR function and to use it.
After the operating system had been installed successfully, reboot your computer, you can see these ACPI
items show up in the
“Device Manager” menu by entering Start Settings Control Panel System
