HP Business Desktops BIOS

Figure 1. Overall BIOS security picture
The following diagram represents the various security levels and interactions enabled by the HP BIOS.
Thermal and Power Management
The HP BIOS provides and enables thermal and power management technologies to assist in
operating the HP Business Desktop computer in any enterprise environment.
Balancing thermal and acoustic requirements
HP designs thermal solutions to help assure that the computer performs optimally in the customer
environment. The HP BIOS actively controls the environment of the computer by balancing the thermal
requirements of the configuration and the acoustic levels of the computer. With today’s faster and
hotter processors, thermal management becomes paramount. If the processor becomes too hot, it may
“throttle” (slow down) the computer until the temperature decreases. Throttling involves reducing the
performance of the processor significantly during periods of elevated temperatures. The HP BIOS
automatically manages the air flow in the computer to minimize elevated temperatures that could lead
to thermal throttling.
The HP BIOS, by default, optimizes the acoustic characteristics of the computer while providing
complete protection for the hardware thermal needs. Some customers may wish to control the
computer airflow in their computers manually. The HP BIOS allows the user or administrator to
configure the nominal fan speed to best suit the work environment. Air flow can be maximized for
environments where thermal concerns are most important or minimized for acoustically sensitive
