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.
If the computer is connected to a network managed by HP Client Manager, the computer sends a fault
notice to the network management application. With HP Client Manager Software, you can also remotely
schedule diagnostics to automatically run on all managed PCs and create a summary report of failed
tests.
Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some 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. The 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.
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.
Thermal Sensor
The thermal sensor is a hardware and software feature that tracks the internal temperature of the
computer. This feature displays an alert message when the normal range is exceeded, which gives you
time to take action before internal components are damaged or data is lost.
