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 displayed by pressing

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

1. Start Computer Setup.

2. Use a pointing device or the arrow keys to select File > System Information.

3. To exit Computer Setup without saving your changes, click the Exit icon in the lower-left corner

of the screen, and then follow the on-screen instructions.

– or –

Use the tab key and the arrow keys to select File > Ignore Changes and Exit, and then press

enter.

Downloading a BIOS update

CAUTION: To reduce the risk of 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 on the computer by unplugging the power cord from the AC outlet.

Do not shut down the computer or initiate sleep.

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

1. From the Start screen, type help and then select Help and Support.

2. In the Help and Support search box, type maintain, and then follow the on-screen

instructions 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 on-screen instructions to download your selection to the hard drive.

Make a note of the path to the location on your hard drive where the BIOS update is

downloaded. You will need to access this path when you are ready to install the update.

NOTE: If you connect your computer to a network, consult the network administrator before

installing any software updates, especially system BIOS updates.
