Cleaning your HP DV2000's cooling fan requires complete disassembly of your laptop.
Your HP DV2000 laptop's CPU cooling fan prevents your computer from overheating from use. However, if not regularly cleaned and maintained, dust and debris can collect overtime and slow down the cooling fan, or cause it to stop working. If your cooling fan stops working, your laptop's processor may overheat and cause permanent damage to your motherboard, which may render your laptop completely useless. You need to disassemble your laptop completely to gain access to your laptop's cooling fan.
Instructions
1. Turn off your laptop and disconnect the power cable, any miscellaneous cables and any external devices. Close the LCD panel, and place the laptop face-down. Disengage the retaining tab securing the laptop battery. Lift the battery out of its compartment and set it aside.
2. Remove the 26 Phillips-head screws from the bottom casing of the laptop. This includes screws securing the RAM, hard drive and wireless card plastic covers, and the screws inside the battery compartment. Place the laptop face-up and then open the LCD screen all the way.
3. Use a small, flat-head screwdriver to pry up the keyboard bezel from the laptop casing, and then disconnect the power and media touchpad cables from the right side of the keyboard bezel. The keyboard bezel is a thin, plastic strip between the keyboard and the LCD screen. Remove the bezel and set it aside. The bezel should come off easily. If it does not, make sure all the Phillips-head screws are removed from the bottom casing of the laptop.
4. Lift up on the keyboard assembly, and then place it face-down of the palm rest. Disconnect the keyboard's black ribbon cable from the motherboard, and then remove the keyboard from the laptop casing and set it aside.
5. Remove the three Phillips-head screws from the top edge of the upper casing assembly, and then remove the single Phillips-head screw located towards the center of the laptop along the right edge of the upper casing. While holding the LCD screen with one hand, remove the two Phillips-head screws from each LCD hinge with the other hand. Lift the LCD screen from the laptop and set it aside.
6. Insert a small, flat-head screwdriver into the crease separating the top casing from the bottom casing along the outside edge of the laptop. Work your way around the entire laptop until the top casing is completely separated from the bottom casing. Remove the upper casing and set it aside.
7. Disconnect all visible connectors from the motherboard, while taking note of their location. Remove all Phillips-screws that secure the motherboard to the bottom casing. Grasp the right edge of the motherboard and begin to lift the motherboard out of the laptop casing. Flip the motherboard over and place it on a clean, flat surface so the CPU cooling fan is facing upwards.
8. Remove the four Phillips-head screws securing the heatsink and cooling fan assemblies to the motherboard, and then disconnect the cooling fan's power cable from the motherboard. Lift the cooling fan and heatsink out of the motherboard and set it aside.
9. Use a compression air duster can to blow the dust and debris out of the cooling fan. Then use a soft cloth, or paper towel to thoroughly clean out the dust and debris between the fan blades.
10. Follow this procedure in reverse to re-assemble your laptop.
