Desktop Management 3.5 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. 3.5.1 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. 3.5.2 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. 3.5.3 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. 3-26 361288-003 Service Reference Guide, dc7100

Fault Notification and Recovery features combine innovative hardware and software technology

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

3.5.1 Drive Protection System

The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in

unwarranted hard drive replacement.

When

computers are built, each installed hard drive is tested using DPS, and a permanent

to the hard drive. Your service provider can use this information to help diagnose conditions that

3.5.2 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.

3.5.3 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.
