							B Software updates
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:

update by identifying the BIOS version currently installed on the computer.
If the computer is connected to a network, consult the network administrator before installing any
software updates, especially system BIOS updates.
NOTE:The computer system BIOS is stored on the system ROM. The BIOS initializes the
operating system, determines how the computer interacts with the hardware devices, and provides
for data transfer among hardware devices, including the time and date.
NOTE:Windows includes the User Account Control feature to improve the security of the
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
Support.

the update later, after it has been downloaded to the hard drive.
b.Follow the instructions on the screen to download your selection to the hard drive.
Make a note of the path to the location on the hard drive where the BIOS update is
downloaded. Access this path when you are ready to install the update.
