3.6 Fault Notification and Recovery
Fault Notification and Recovery features combine innovative hardware and software technology
to prevent the loss of critical data and minimize unplanned downtime.
When a fault occurs, the computer displays a Local Alert message containing a description of the
fault and any recommended actions. You can then view current system health by using the HP
Client Manager Software. If the computer is connected to a network managed by HP Insight
Manager, HP Client Manager Software, or other system management applications, the computer
also sends a fault notice to the network management application.
3.6.1 Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in
select HP computers. DPS is designed to help diagnose problems that might result in
unwarranted hard drive replacement.
When HP computers are built, each installed hard drive is tested using DPS, and a permanent
record of key information is written onto the drive. Each time DPS is run, test results are written
to the hard drive. Your service provider can use this information to help diagnose conditions that
caused you to run the DPS software. Refer to the Troubleshooting Guide for instructions on
using DPS.
3.6.2 Surge-Tolerant Power Supply
An integrated surge-tolerant power supply provides greater reliability when the computer is hit
with an unpredictable power surge. This power supply is rated to withstand a power surge of up
to 2000 volts without incurring any system downtime or data loss.
3.6.3 Thermal Sensor
The thermal sensor is a hardware and software feature that tracks the internal temperature of the
computer. This feature displays a warning message when the normal range is exceeded, which
gives you time to take action before internal components are damaged or data is lost.
