HP CoolSense (select models only) HP CoolSense automatically detects when the computer is not in a horizontal position and adjusts performance and fan settings to keep the surface temperature of your computer at the optimum level of comfort. When HP CoolSense is off, the position of the computer is not detected and the performance and fan options remain at the factory setting. As a result, the surface temperature of the computer might be higher than it would be with HP CoolSense on. To turn CoolSense off or on, follow these steps: ▲ From the Start screen, type cool, select Settings, and then select HP CoolSense. 44 Chapter 6 Managing power
