Abstract
A method for regulating power dissipation at an information handling system may include determining a present value of a first parameter, the first parameter controlling an operating frequency, frequency boost, and a supply voltage at a central processing unit. The method may further include determining a present value of a second parameter, the second parameter defining a user's preference for optimizing operation of the system for noise level, skin temperature, and performance. The method may further include determining that a program executing at the system is specified at a list of software applications. In response to determining that a skin temperature of the system exceeds a threshold, the first parameter may be adjusted to reduce power dissipation of the CPU by a first amount if the value of the second parameter is equal to a first value. The first parameter may be adjusted by a second amount if the present value of the second parameter is equal to a second value.
