That's why we test Inspiron laptops for reliability not just in the places where you expect it, but for the open road ahead. Turn up the heat: From locker rooms to locked cars, we test Inspiron laptops for survival in harsh short-term heat conditions of up to 65°C/149°F. Everything hinges on it: We test Inspiron laptop hinges to ensure they still feel tight, even after opening and closing the lid 20,000 times. Keys to success: We test commonly used keys for 10 million keystrokes and touch pad buttons 1 million times with no failure. So go ahead, finish your novel. Buttoned up: No matter what you set your power and multimedia buttons to do, we've tested them all to survive up to 40,000 pushes.
