that HP Business Desktop computer designs will enable the latest processor and operating system
thermal and power management technologies. The HP BIOS also provides runtime power
management for some configurations that support processor throttling of frequency and vol
situations where the operating system detects excess computing capability for the tasks it needs to
perform. Runtime power management involves lowering the processor’s power requirements when
computer is not executing processor intensive activities. The computer is completely on and responsive
to the user, but, when the processor is not fully engaged, it can be throttled to save up to 40% power
consumption without affecting the user’s productivity. Typically, this feature is available in high
performance processors. These computers can dissipate system power, up to 90W idling at norm
operating frequency and voltage and significantly more in the working state. The runtime power
management feature can save tens of KWHs per machine per year without sacrificing computing
performance.

diagnosing problems. Visual alerts are produced by blinking the power LED light red instead of the
normal green color. Audio beep alerts are supported on computers containing a computer speaker.
These alerts allow the user, administrator, or service technician to diagnose problems quickly at the
component level and take effective action onsite. Issues can be diagnosed correctly the first time to
avoid random replacement of computer components and costly computer downtime. See the
Troubleshooting Guide on the Documentation CD that shipped with the computer for more
information. Problem alerts are provided for the following failures:
Problem Computer Reaction
Processor Thermal Protection Activated D 2 times, one every second, followed Power LED blinks RE
by a 2-second pause.
Processor not installed (not an indicator for a bad es, one every second, followed
