Watchdog

A watchdog timer (WDT) is a device that performs a specific

operation after a certain period of time if something goes

wrong and the system does not recover on its own. A watch-

dog timer can be programmed to perform a warm boot

(restarting the system) after a certain number of seconds.

Hardware Monitor

The Hardware Monitor (HWM) API is a system health super-

vision API that inspects certain condition indexes, such as

fan speed, temperature and voltage.

CPU Speed

Makes use of Intel SpeedStep technology to save power con-

sumption. The system will automatically adjust the CPU

speed depending on the system loading.

System Throttling

Refers to a series of methods for reducing power consump-

tion in computers by lowering the clock frequency. This API

allows the user to adjust the clock from 87.5% to 12.5%.
