The hibernate mode is characterized by a complete power disconnection. But before switching off, the whole content of operating memory is copied on the hard disk. During the next launching, a system automatically restores the operation from the position of the last stoppage by rewriting the stored information from the hard disk into an operating memory. For example, if you are downloading some information from the Internet using standard Windows tools and your computer goes to the hibernate mode, the downloading will be continued after the system recovery.
To select the power control mode, use the parameter “ACPPI Suspend Type” (ACPI Standby state) which may have two values: S1 (POS) – the Power On Suspend Mode is on; and S3 (STR) – the Suspend to RAM Mode is on. If a value S1 is on, only the Suspend mode will be available for your computer, and a value S3 is on – both the Suspend and Hibernate modes will be available. But if you use Windows98 that does not support the opportunity to save operating memory on the hard disk, the Hibernate Mode may still be unavailable. To use such mode, your system should have the ability to fuel memory with the information about a system state.
To get to the power saving mode, use the parameter “Suspend-to-RAM Capability” which may have three values: Enabled, Disabled and Auto.
