Users Guide

Power
The Power feature improves the battery life of your system by configuring and switching productivity on usage behaviors. It
learns the battery usage on the system, and uses AI and machine learning models to apply appropriate charge policies. This
feature also identifies opportunities to extend the battery run time.
Dell Optimizer learns the discharge patterns, discharge rates, state of battery health, and classifies the users into the following
four profiles:
● Desktop replacement—Always connected to a power source and rarely uses battery.
● Corridor warrior—A standard office user with a general charge cycle.
● Performance users—Uses processor heavy applications which have a high battery discharge rate.
● Marathon users—Generally discharges the system completely.
Dell Optimizer takes two weeks to learn the user's behavior, and adjusts their profile after each two-week learning period when
needed.
Optimizing power
1. Go to Power section and click
.
The Power section is displayed.
NOTE: You can enable or disable this feature by using the toggle switch.
2. Click the Adaptive battery performance toggle button to extend the battery run time based on the user behavior.
This feature allows you to extend the battery runtime by intelligently taking battery saving measures. It turns on the windows
power saver mode, reduces the processor power level, and dims the screen.
NOTE:
Some users may experience an impact on system performance when you apply the Adaptive Battery
Performance optimization settings.
3. Use the Dynamic charge policy toggle switch, to enable the correct charge policy.
This feature ensures that the system automatically switches the charging policies between, Always AC, Express Charge, and
Standard, according to the usage pattern of user.
NOTE:
If you have purchased a long cycle life battery with a three-year warranty, the Dynamic charge policy toggle
switch is disabled. A long cycle life battery is locked in one charging mode, and the system cannot switch between
different charging modes.
Proximity Sensor
Proximity sensor is an integrated feature in selected Dell laptops and mobile workstations. The sensor detects your presence
when you are in front of your system and within the field-of-view (FOV) of the sensor. When you move out of the FOV, the
brightness of your system display reduces, and locks your system that is based on the lock time settings. When you walk in to
the FOV, the system display turns on and the login screen appears.
When enabled, it can be accessed when the system is on or in modern standby state, and when the system is in clamshell or
tablet mode.
Proximity Sensor supports the following capabilities:
● Walk Away Lock—When you move out of the FOV, the system locks, and the display is turned off based on the preferred
lock time settings. The system then enters modern standby state. This feature secures your system and saves power when
you are away from it. By default, the Walk Away Lock button is enabled, and the screen lock timer is set to 60 seconds. The
Walk Away Lock is suspended when:
○ Snooze is enabled in Dell Optimizer.
○ User activity is detected through a keyboard, mouse, or a touchpad.
○ An application running on the system is requesting audio or display power from the operating system. For example, when
you are using Skype during an active call, and when you are streaming video in Windows Media Player.
○ An external monitor is connected, and the proximity sensor feature is disabled.
