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

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.
The Hardware Monitor (HWM) API is a system health super-
vision API that inspects certain condition indexes, such as
fan speed, temperature and voltage.
Makes use of Intel SpeedStep BIOS technology to save
power consumption. The system will automatically adjust the
CPU speed depending on the system loading.
Refers to a series of methods for reducing power consump-
