Laptop and desktop computers are vulnerable to overheating. The electronic components operate at a specific current induced by a low voltage. The sensitivity of the components means that even a small fluctuation in voltage is dangerous. Excessive heat lowers the electrical resistance of objects, therefore increasing the current. In addition, slowdown is a result of overheating. Components can shut down when overheated and the motherboard temperature sensor instructs hardware such as the hard drive and processor to slow down. The ideal operating temperature of a computer's environment ranges from 50 degrees F to 82 degrees, though it should be as close as possible to room temperature, 72 degrees. Laptops should operate between 50 and 95 degrees. If the room is too hot, cool air cannot enter the computer and keep temperatures from rising too high. In cold rooms, moisture can cause internal condensation; water damages running electrical components.
