Switchable graphics (select models only)
Select computers are equipped with switchable graphics. Switchable graphics are supported by both
AMD™ and Intel. If your computer has AMD dynamic switchable graphics, it supports only switchable
graphics.
NOTE: To determine whether your computer supports switchable graphics, see your notebook
graphics processor configuration. Intel Central Processing Units (CPUs) and AMD Accelerated
Processing Units (APUs) support switchable graphics.
Switchable graphics offers two modes for processing graphics:
● Performance mode—Runs application with optimal performance.
● Power Saving mode—Conserves battery life.
Using switchable graphics (select models only)
Switchable graphics allow you to switch between Performance mode and Power Saving mode.
Switchable graphics assigns individual applications to either Performance mode or Power Saving
mode, based on power requirements. You can also manually modify the settings for an individual
application and switch between Performance mode and Power Saving mode.
NOTE: For more information, see the switchable graphics software Help.
