of TPM-enabled PCs to the corporate network.
HP ProtectTools Security Manager can be configured to prevent unauthorized access using Smart
Cards, TPM Embedded security chips, USB tokens and other security technologies. HP
ProtectTools Security Manager is completely customizable, providing the flexibility to choose

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.
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, you can also
remotely schedule diagnostics to automatically run on all managed PCs and create a summary
report of failed tests.
3.6.1 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. 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.
