Here is how to change graphics modes on the PowerSpec 1510 or 1710 laptops:
Open the built-in Control Center by pressing the FN+ESC keys on the keyboard.
Under GPU Switch, select between MSHYBRID (Microsoft hybrid Graphics Mode) and DISCRETE (Discrete Graphics Mode).
MSHYBRID will automatically switch between the integrated and GTX 1070 when necessary, while the DISCRETE mode will force the system to use the GTX 1070 for all applications. MSHYBRID is the default graphics mode.
