Dell Precision 5550 Setup and Specifications

NOTE The top and the sides of the touchpad—8.20 mm (0.32 in.) from the edges—are disabled. This prevents unintended movements of the mouse pointer when using the keyboard.

NOTE The touchpad area of the computer is large and your palms may inadvertently touch the touchpad corners when the touchpad is in use. To prevent this, the physical button and the corners of the touchpad ( 1 cm x 1 cm or 0.39 in. x 0.39 in.) will be ignored and disabled if other touches are detected outside of these corners.
