Power Management
Dell Longevity Mode
Frequently connecting and disconnecting your computer to a power source
without allowing the battery to fully discharge may reduce battery life.
The longevity mode feature protects the battery health by moderating
the extent to which your battery charges, and prevents your battery from
frequent charge and discharge cycles.
Your Dell laptop automatically monitors the charging and discharging
behavior of your battery, and if applicable, displays a message requesting
you to enable longevity mode.
NOTE: Dell longevity mode may not be supported on all laptops.
To configure Dell longevity mode:
1. Right-click the battery icon on the Windows notification area and click
Dell Extended Battery Life Options.
The Battery Meter dialog box appears.
2. Click the Longevity mode tab.
3. Click Enable to turn on, or Disable to turn off Dell longevity mode.
4. Click OK.
NOTE: When longevity mode is enabled, the battery charges only
between 88% – 100% of its capacity.
Dell Desktop Mode
If you primarily use your computer with the power adapter connected,
you can enable the desktop mode to moderate the extent to which your
battery is charged. This reduces the number of charge/discharge cycles and
improves battery life.
Your Dell laptop automatically monitors the charging and discharging
behavior of your battery, and if applicable, displays a message requesting
you to enable Desktop Mode.
NOTE: Dell desktop mode may not be supported on all computers.
To enable or disable desktop mode:
1. Right-click the battery icon on the Windows notification area, and then
click Dell Extended Battery Life Options.
The Battery Meter dialog box is displayed.
2. Click the Desktop mode tab.
3. Click Enable or Disable based on your preference.
