What is Suspend-to-RAM?
Suspend to RAM (STR) is a technology that is closely associated with the S3 state of the ACPI specification. STR allows a properly configured system to go into a low power state while saving information to main memory about the system’s configuration, open applications, and active files. While in the low power (STR) state, memory remains powered to retain the system information while most other components turn off to conserve energy. Fans are turned off to provide silent operation and to minimize power consumption. Properly configured systems in STR typically can use less than 5 watts. The system can be left in the STR State and can be awakened periodically to perform preprogrammed events such as downloading e-mail or searching and filtering web content. A network access or an incoming phone call can also wake the PC and trigger a desired response, similar to a telephone answering machine. When an incoming request arrives via a “wake device” or the user wishes to resume operation, the
