Remove the cooling fan from your HP Pavilion dv9000 laptop.
Every laptop comes built with a dedicated cooling system. The cooling system consists of a heat sink and a cooling fan device. In HP dv9000 laptops, the cooling fan sits directly over the processor chip. The fan’s main function is to regulate the processor’s temperature so that the processor does not overheat and damage the laptop’s motherboard. Since the fan sits on top of the processor, removing the fan is necessary to access the processor chip.
1. Shut down your laptop. Close the display panel and then disconnect the power cable and all external devices.
2. Place the laptop face-down with the front edge facing you. Remove the battery pack from its compartment in the upper left corner of the laptop.
3. Remove the hard drive compartment covers from the lower right and left corners of the laptop. Each cover is secured in place by two Phillips-head screws. Grasp each hard drive by its plastic pull-tab. Tilt each drive upward at an angle to disconnect the drive from its connector. Remove each drive from its compartment.
4. Remove the memory compartment cover and its two retaining Phillips-head screws from the center of the laptop’s bottom casing.
