This is normal behavior for this system with this amount of installed memory.

One of the many such articles on the 'net; this easy-to-read article explains "Installed memory compared to usable memory"

What is the difference between physical memory and available memory?

Don't like that article?

Search for one that better suits your need.

For example, search for something similar to:

installed memory does not match available memory

Once the BIOS is updated along with your Windows Updates and other HP Software and Drivers, the use of the memory is controlled by the system.  The BIOS  "Advanced", not usually available in consumer grade systems, is not relevant to your computer's setup.
