According to studies, drops while carrying a laptop are the most common reason for laptop failure and drops during operation are the third most common reason. The word "drop" however, may refer to significantly different things: depending on the drop height and conditions of impact, the force of impact on the PC will be different. That's why Panasonic carries out free fall tests from three heights: 4 to 6 inches (to simulate the action of a careless drop onto a desk), 12 inches (to simulate the force of impact of a computer inside a bag being chucked onto a desk), 30 inches (to simulate the fall of a computer that is knocked off a desk or dropped during carriage). All Toughbook business-rugged models must pass all of these tests as part of their rugged design.
