Resetting BIOS Defaults Via the Reset Defaults Option

If the system is able to complete POST.

• Restart the system. Click on Start, Turn off Computer and Restart.
• At the Dell loading screen Tap F2 to enter the BIOS. "Entering Setup" will appear when the command has been recognised. Certain models may use a different key. The key will be displayed during the boot process. For most Dell laptops and desktops, the key is F2.
• Once loaded, depending on BIOS age and type, you can reset the defaults by either using F9 key to Load Defaults (Shown as an option at the bottom of the screen), the Alt + F key combination, or the Load Defaults button shown on the screen, to load the factory defaults.
• Press Esc on your keyboard and select Save and exit, or click the Exit button, again depending on the version you have.
• Choose the Enter key to save all changes and exit the BIOS screen. Allow your system to restart for the BIOS settings to reset.

NOTE: This is a different function from clearing the CMOS/NVRAM and only returns the system to its factory default settings, it does NOT clear the ESCD.
