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 on the Documentation and Diagnostics CD
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 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.
