Replacing your HP Pavilion laptop's video card to fix video processing problems.
An HP Pavilion dv8000 comes with an internal video chip attached to the motherboard. The video chip is responsible for all video and graphics processing. If the video chip isn't working correctly, a variety of video processing issues from slow videos and videos that glitch to a completely blank screen may occur. Repairing a bad video chip means completely dismantling the HP laptop and replacing the chip.
Instructions
1. Turn off the laptop and close it. Unplug the main power cord. Disconnect all peripheral devices. This usually includes any networking, data storage or external monitoring devices. Turn the laptop over so that is face down with the front edge facing toward you.
2. On the bottom of the laptop, locate the battery release button on the left hand side of the machine. Slide the battery release button to the left and remove the battery pack from its compartment.
3. Locate the the hard drive compartment cover that lines the lower section of the laptop. Remove the three Phillips head screws from this cover. Lift the cover off. This will reveal the dual hard drives inside the compartment. Carefully slide each hard drive away from its data connector to disconnect from the motherboard. Lift each drive out of the compartment. Put the hard drives into static-resistant plastic bags.
4. Remove the two Phillips screws from the memory compartment cover situated above the now-empty hard drive compartment. Lift the cover off and set it aside. The internal memory will now be visible. It has two modules. Pull apart the spring-loaded clips on each side of both memory modules. Slide each module out of its individual socket. Place the memory modules into a static-resistant plastic bag.
5. Unplug the two antenna cables from the wireless card located inside the empty memory compartment. Spread apart the card's retention clips and slide the card out of its socket. Place the wireless card in a static-resistant plastic bag.
6. Locate the Phillips head screw fastening the DVD drive to the upper-left corner of the laptop. Unbend the paper clip and insert it into the release hole on the face of the DVD drive. Push the paper clip into the hole until the drive ejects from the compartment. Pull the DVD drive out of the laptop and set it aside.
7. Remove all Phillips head screws from the laptop's base enclosure. This includes all screws located inside the vacant hardware compartments. Flip the laptop over and open the top. Locate the hinge cover. It is situated at the base of the LCD panel. Pry the hinge cover off with a flat-head screwdriver.
8. Grasp the top edge of the keyboard from behind the top row of keys. Tilt the keyboard assembly upward and unplug the keyboard's ribbon cable from the motherboard. Remove the keyboard assembly from the laptop and set it aside.
9. Disconnect the LCD video cable extending from the left side of the display panel to the video chip in the upper left corner of the motherboard. Remove the Phillips head screws from each LCD panel hinge and lift the panel off the laptop's base. Relocate the panel to a padded surface with the screen facing upward.
10. Remove the five Phillips head screws from the palm rest area. Unplug the small ribbon cable extending from the touchpad device to the motherboard. Carefully lift the entire palm rest assembly off the laptop and set it aside. This will reveal and provide access to the entire top side of the motherboard.
11. Remove the Phillips head screws from the video chip in the upper left corner of the motherboard. Lift the chip out of the laptop and set it aside. Use a can of compressed air to blow out all dust and debris from the video card's connector socket on the motherboard.
12. Reverse the dis-assembly procedure to install the new video card chip. Then turn on the computer and insert the driver installation disc that came with the replacement video card. Follow the on screen instructions to complete the installation.
