Updating the Bios

To update the BIOS, first determine what BIOS version you currently have and then download and install the new BIOS.

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 displayed by pressing fn+esc (if you are already in Windows) or by opening the Setup Utility.

To use the Setup Utility for displaying BIOS information:

1.Open the Setup Utility by turning on or restarting the computer. While the “Press the ESC key for Startup Menu” message is displayed in the lower-left corner of the screen, press f10.

2.If the Setup Utility does not open with the system information displayed, use the arrow keys to select the Main menu.

When the Main menu is selected, BIOS and other system information is displayed.

3.To exit the Setup Utility, use the arrow keys to select Exit > Exit Discarding Changes, and then press enter.

Downloading a BIOS update

CAUTION: To prevent damage to the computer or an unsuccessful installation, download and install a BIOS update only when the computer is connected to reliable external power using the AC adapter. Do not download or install a BIOS update while the computer is running on battery power, docked in an optional docking device, or connected to an optional power source. During the download and installation, follow these instructions:

Do not disconnect power from the computer by unplugging the power cord from the AC outlet.

Do not shut down the computer or initiate Sleep or Hibernation.

Do not insert, remove, connect, or disconnect any device, cable, or cord.

To download a BIOS update:

1.Access the page on the HP Web site that provides software for your computer:

Select Start > Help and Support, and then click the link for software, driver, and BIOS updates.

2.Follow the instructions on the screen to identify your computer and access the BIOS update you want to download.

3.At the download area, follow these steps:

a.Identify the BIOS update that is later than the BIOS version currently installed on your computer. Make a note of the date, name, or other identifier. You may need this information to locate the update later, after it has been downloaded to your hard drive.

b.Follow the instructions on the screen to download your selection to the hard drive.
