# Suspend Power Management state

Source: [https://docs.qualcomm.com/doc/80-70015-30/topic/suspend-power-management-state.html](https://docs.qualcomm.com/doc/80-70015-30/topic/suspend-power-management-state.html)

The Suspend state is the deepest sleep state in the APSS with all user space
        processes frozen and drivers releasing their resources. During the Suspend state, all cores
        enter the C4 state followed by the AOSD Sleep state.

Note: The Suspend state is enabled for QCS6490/QCS5430. For QCS9075,
            this feature will be enabled in a future release.

A user space module can configure the Suspend state using the following command:

`echo mem > /sys/power/autosleep`

## Check suspend statistics

To display suspend statistics run the following commands:

cd /sys/power/suspend_stats
    cat success
    cat failCopy to clipboard

The success count indicates the number of times the APSS has successfully entered the
                Suspend state while the fail count indicates the number of times the APSS has failed
                to enter the Suspend state.
