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.

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

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.

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.
