    management/battery conservation configurations, battery fast charging, and software applications.
    Exhaust air is displaced through the ventilation grill located on the left side of the computer.
    Before removing the fan/heat sink assembly, follow these steps:
    1.Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the
    computer on, and then shut it down through the operating system.
