7 Using Setup Utility (BIOS) and HP PC

Hardware Diagnostics (UEFI)

Setup Utility, or Basic Input/Output System (BIOS), controls communication between all the input and

output devices on the system (such as disk drives, display, keyboard, mouse, and printer). Setup

Utility (BIOS) includes settings for the types of devices installed, the startup sequence of the

computer, and the amount of system and extended memory.

Starting Setup Utility (BIOS)

To start Setup Utility (BIOS), turn on or restart the computer, quickly press esc, and then press f10.

NOTE: Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the

computer from operating properly.

Updating the BIOS

Updated versions of the BIOS may be available on the HP website.

Most BIOS updates on the HP website are packaged in compressed files called SoftPaqs.

Some download packages contain a file named Readme.txt, which contains information regarding

installing and troubleshooting the file.

Determining the BIOS version

To determine whether available BIOS updates contain later BIOS versions than those currently

installed on the computer, you need to know the version of the system BIOS currently installed.

BIOS version information (also known as ROM date and System BIOS) can be revealed by pressing

fn+esc (if you are already in Windows) or by using Setup Utility (BIOS).

1. Start Setup Utility (BIOS) (see

Starting Setup Utility (BIOS) on page 93).

2. Use the arrow keys to select Main.

3. To exit Setup Utility (BIOS) without saving your changes, use the arrow keys to select Exit,

select Exit Discarding Changes, and then press enter.

4. Select Yes.
