Using HP CoolSense (select models only)

When you are using your computer on the move or when lounging around the house, HP CoolSense

helps deliver the optimum level of comfort by automatically adjusting performance and internal fan settings.

When HP CoolSense is on, it automatically detects if your computer is not in a stationary position and makes further adjustments to performance and fan settings to keep the surface temperature of your computer at the optimum level of comfort.

When HP CoolSense is off, performance and fan settings are not adjusted beyond your computer's default cooling settings. When your computer is not in a stationary position, the surface temperature of your computer may therefore be higher than it would be with HP CoolSense on.
