The Panasonic CF-52 is a rugged Toughbook released by Panasonic in 2007. It is primarily targeted at niche markets that require extra-durable laptops, such as military, forestry and criminal justice organizations. The CF-52 features a “Function” key that can be pressed to toggle the function of other keys on the keyboard. When the laptop is functioning normally, the key will not stay active, and its effect should not be noticed when the key is not actively being pressed. Due to a driver error in some models, however, the key can malfunction. Fixing this problem is as simple as installing a new driver. Writer Bio
