laptop suspend commands

• STI (suspend-to-idle) is a generic, pure software, lightweight system sleep state. Together with platform-specific driver enhancements, this state can be used to reach the S0i3 state on Intel platforms. To enter this state, run the shell command:

    echo freeze > /sys/power/state

• STR (suspend-to-RAM) offers significant power savings as everything in the system except memory is put into a low-power state. Memory should be placed into the self-refresh mode to retain its contents. ACPI platforms are in S3 after suspending to RAM. To enter this state, run the shell command:

    echo mem> /sys/power/state

• Hibernation (hibernate-to-disk) operates similarly to Suspend-to-RAM, but includes a final step that writes memory contents to disk. On resume, this is read and memory is restored to its presuspend state. Usually, the ACPI platform is in S4 state after suspending to disk. To enter this state, run the shell command:

    echo disk > /sys/power/state
