NOTE:
To properly ventilate the computer, allow at least a
7.6-cm
(3-inch) clearance on the right
side and rear panel of the computer. The computer uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to turn on automatically when high temperature
conditions exist. These conditions are affected by high external temperatures, system power
consumption, power management/battery conservation configurations, battery fast charging, and
software requirements. 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.
2.
Disconnect all external devices connected to the computer.
3.
Disconnect the power from the computer by first unplugging the power cord from the AC outlet
and then unplugging the AC adapter from the computer.
