UEFI
BIOS is the first program that the computer runs.
When the computer turns on, the UEFI BIOS performs a self test to
make sure that various devices in the computer are functioning properly.
Enter the UEFI BIOS menu
Turn on or restart the computer. When the logo screen is displayed, press F1 repeatedly to enter the UEFI BIOS menu.
Reset system to factory defaults
This feature enables you to reset the UEFI BIOS to the factory default settings, including all UEFI BIOS settings and internal system data. It helps you wipe user data in case that you want to dispose of or reuse your computer.
Update the UEFI BIOS
When you install a new program, device driver, or hardware component, you might need to update the UEFI BIOS.
