Chapter 4. Firmware setup utility
Your PC's firmware is a piece of software that is stored on the PC's CMOS chip. Firmware plays a key role in
the operation of the PC. When you turn on the PC, the firmware checks and initiates the PC's hardware
devices. It also checks the boot device for completeness and security, before executing the code to start up
the operating system.
A Lenovo PC usually provides a setup utility for you to change some firmware settings. You can use
Windows advanced startup to restart your PC and open the firmware setup utility. Alternatively, you can
access the setup utility from the Novo button menu.
Many firmware settings are also available in Lenovo developed apps, such as Lenovo PC Manager and
Lenovo Vantage. For daily use of your PC, you should use the firmware setup utility very rarely.
