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 from 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. If the update is more recent than your BIOS, 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 revealed on the screen after the download
is complete. If no instructions are revealed, follow these steps:
1. From the Start screen, type file, and then select 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.
Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside
the operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.
