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

and the system does not recover on its own. A watchdog
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 condition indexes such as fan speed,
temperature, and voltage.
