In the case of a laptop where power may be scarce, the importance of power savings should supersede the screen saver.
Off mode is the deepest level of power management, resulting in the greatest power savings and the longest recovery time.
The values of successive power levels must be greater than or equal to the value of the previous (non-zero) level.

 Documentation
If a VESA Display Power Management Signaling (DPMS)-compliant monitor is being used, enabling POWER MANAGEMENT reduces monitor power consumption during periods of keyboard and mouse inactivity.
But in all cases, power consumption decreases when a monitor transitions from on (full power) to standby mode (reduced power, where the image on the monitor screen usually disappears).
When POWER MANAGEMENT is set to DISABLED, the disks spin constantly as long as the system is turned on.

Monitors constitute a large percentage of the power used by a workstation even when not actively in use (such as during screen blanking).
To reduce the power consumption, the Video Electronic Standards Association (VESA) has defined a Display Power Management Signaling (DPMS) standard that can be used to greatly reduce the amount of power being used by a monitor during screen blanking.
The actual amount of power saved and the recovery time for each of the states is monitor-dependent and can widely vary.
