Power Conservation: Dell™ Inspiron™ 3700 System Reference
Experimenting With Power Conservation
In general, the lower the value you set for each power conservation feature, the longer the battery's charge lasts. On the other hand, setting high
values tends to optimize the computer's performance.
To evaluate the way that different settings affect how long you can operate the computer on battery power versus the relative efficiency of how the
software performs, experiment as follows:
l Use the computer with all the options set at their default values.
l
Use the computer with all the options disabled or set to Off.
l Use the computer with all the options set to their minimum or maximum values.
