BIOS
How do I access my BIOS?
Resolution: You can access the BIOS by pressing CTRL+ALT+ESC as the system is booting. At the bottom of the second start up screen you should see "To enter setup, press CTRL_ALT_ESC".
Note: If the system displays the Acer Splash Screen, once you hear the beep, you should begin pressing CTRL+ALT+ESC. You may need to press CTRL+ALT+ESC continuously until you access the BIOS setup screen.
