This document pertains to HP Notebook PCs with HP CoolSense Technology and Windows 7 or 8..
HP CoolSense Technology is a feature in some HP notebook computers that combines hardware, software, and mechanical design to dynamically manage the temperature of your notebook computer, and help keep you comfortable while using it. HP CoolSense Technology uses a motion sensor in your notebook computer to sense when your computer is being used in a stationary or mobile setting, and automatically adjusts the computer performance and fan speed to keep the computer cool. HP CoolSense software allows you to specify your cooling preferences. Use this document to configure and use your HP CoolSense software.

Configuring HP CoolSense 1.0 (older version)

    The modes are:
    • Stationary mode - When the motion sensor detects that the computer is on a stable, stationary surface (such as a desk or a table), the option selected here is used for cooling.
    • Mobile mode - When the motion sensor detects that the computer is in a mobile setting (such as a sofa or a chair), the option selected here is used for cooling.
    The cooling options for each mode are:
    • Coolest Mode - Select this option to maintain the coolest temperature possible. The fan spins more frequently and the computer performance is adjusted to avoid temperature increases.
    • Performance Optimized Mode - Select this option to maintain the highest computer performance possible. The computer might become warm to the touch as the CPU is allowed to run at full capacity. The fans may run frequently, and at higher speeds, to help keep the computer temperature down.
    • Quietest Mode - Select this option to run as quietly as possible. Computer performance is adjusted to keep the computer cool so the fans do not need to run very often or at a high speed.
  5. Click Apply to save the changes and exit the HP CoolSense and the HP Support Assistant programs.
