Downloading a BIOS update

CAUTION:
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. Access the HP website, http://www.hp.com.
2. Select Support, and then select Download drivers.
3. Enter the product name in the text box, and then select Go.
4. Select your computer model, and then select your operating system.
5. In the BIOS section, follow these steps:
a. Identify the most recent BIOS update and compare it to 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. If the update is
more recent than your BIOS, 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.
BIOS installation procedures vary. Follow any instructions that are displayed on the screen after the
download is complete. If no instructions are displayed, follow these steps:
1. From the Start screen, type e, and then click File Explorer.
2. Click your hard drive designation. The hard drive designation is typically Local Disk (C:).
3. Using the hard drive path you recorded earlier, open the folder on your hard drive that contains the
update.
4. Double-click the file that has an .exe extension (for example, filename.exe).
The BIOS installation begins.
5. Complete the installation by following the on-screen instructions.
NOTE: After a message on the screen reports a successful installation, you can delete the downloaded file
from your hard drive.
