Downloading a BIOS update for Windows 8
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 support, and then select the HP Support Assistant app.
2. Click Updates and tune-ups, and then click Check for HP updates now.
3. Follow the on-screen instructions.
4. At the download area, 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.
