  User selectable CPU-Full-Performance-lock-mode with applet indicator and Silent-FAN-speed-mode

   Disclosed is a method of User selectable CPU-Full-performance-lock-mode with applet indicator and Silent-Fan-speed-mode.

Fig.1 shows a Block diagram of this User selectable CPU-Full-performance-lock-mode with applet indicator and Silent-Fan-speed-mode. Fig.2 shows a Flowchart of this User selectable CPU-Full-performance-lock-mode with applet indicator and Silent-Fan-speed-mode. Fig.3 shows a Relationship between THERM signal for ICH and Performance.

Fig.4 shows an example of applet indicator of CPU-Full-performance-lock-mode.
