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.
