4.2.2.1.2 Thermal Management 
This BIOS feature controls the activation of the Thermal Monitor’s automatic 
mode. It allows you to determine when the Pentium M4’s Thermal Monitor should 
be activated in automatic mode after the system boots. In general, the Thermal 
Monitor should not be activated immediately on booting since the processor will 
be under a heavy load during the booting process, which results in the sharp rise 
in die temperature from its cold state, which leads to the unstable system. 
Therefore, to ensure optimal booting performance, the activation of the Thermal 
Monitor must be delayed for a set period of time. But how do you possibly know 
the optimal delay time? It is recommended that you set this to its lowest value 
that exceeds the time it takes to fully boot up your computer. 
This item will monitor the CPU thermal to prevent the CPU damage from high 
temperature.
