Your computer's BIOS screen can be incredibly useful when
you need to make certain hardware or system configurations.
How to access the BIOS on your laptop varies from
manufacturer to manufacturer and model to model.
Even though Acer laptops are created by the same
manufacturer, not all models access BIOS in the same manner.
While accessing the BIOS setup screen in and of itself is
not difficult all you need to do is press a key the difficulty is in figuring
out which key to hit.
Restart or power on the laptop.
Hit the "Pause/Break" key the moment the Acer boot
screen (not the OS start-up screen) appears.
If the OS start-up screen appears before you can hit
Pause/Break, you will need to restart the laptop.
Press "F2" or "Del" to access the BIOS
Depending on the age of your Acer laptop, you may need to
instead press "Ctrl," "Alt" and "Esc"
simultaneously to access BIOS.
Using the arrow keys navigate failsafe or
optimized defaults press F10 to safe to cmos and exit to restart.
