827040-001- Fan 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.. Source: printed page 62.
Preparation
Save your work and shut the computer down through the operating system, unplug AC power and every external device, and work on a clean, grounded, ESD-protected surface while sorting each screw by its original location. Handle every cable by its connector and put each one back in its own place during reassembly.
