Updated versions of the software provided with the computer might be available on the HP website.
Most software and 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 about installing
and troubleshooting the software.
To update the software:
1. Identify the computer model, product category, and series or family. Prepare for a system BIOS
update by identifying the BIOS version currently installed on the computer.

operating system, determines how the computer interacts with the hardware devices, and provides
for data transfer among hardware devices, including the time and date.

computer. You might be prompted for your permission or password for tasks such as installing
software, running utilities, or changing Windows settings. For more information, see Help and
