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) is displayed by pressing fn
+esc (if you are already in Windows) or by opening Setup Utility.
To use Setup Utility for displaying BIOS information:
1. Open Setup Utility by turning on or restarting the computer. While the “Press the ESC key for
Startup Menu” appears, press the f10 key.
2. If 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 appears.
3. To exit Setup Utility, use the arrow keys to select Exit > Exit Discarding Changes, and then press
the enter key.
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:
Do not disconnect power from the computer by disconnecting 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. Select Start > Help and Support > Maintain > Software Updates to access the page on the HP
Web site that provides software for the computer.
2. Follow the instructions on the screen to identify the computer and access the BIOS update you
want to download.
3. In the download area
a. Identify the BIOS update that is later than the BIOS version currently installed on the computer.
Make a note of the date, name, or other identifier. You might need this information to locate
the update later, after it has been downloaded to the hard drive.
b. Follow the instructions on the screen to download your selection to the hard drive.
Make a note of the path to the location on the hard drive where the BIOS update is
downloaded. Access this path when you are ready to install the update.
