How to Remove a Video Chip From a Pavilion dv9700

Offered by HP in 2008 and outfitted with either the NVIDIA GeForce GO 7150 or NVIDIA GeForce 8400M graphics chipsets, dv9700 models were better suited as entertainment PCs rather than serious gaming machines because of mediocre video performance. Airflow is often a problem for dv9700 users that use the notebooks on surfaces that restricts the free flow of air from the fans on the bottom of the unit. Restricted airflow causes heat, which often leads to a video chip failure. HP does not cover the video chip repair under warranty. Therefore, if your dv9700 has a faulty graphics chip, you can save some money by removing the chip and replacing it yourself.

Things You'll Need

  • Phillips screwdriver
  • Antistatic wrist strap
  • Awl or small flathead screwdriver
  • Desoldering tool
  • Flux brush or solder wick
  • Canned air
  • Cotton swabs and denatured alcohol


    • 1

      Power off the dv9700 if you have not already done so. Close the LCD screen and disconnect the AC power adapter. Turn the dv9700 over and lay it face down. Unlock the battery pack and remove it.

    • 2

      Remove the screws from the plastic cover plates on the bottom of the dv9700. All three of the cover plates are beneath the battery pack bay. The plate on the right side covers the primary hard drive while the center plate protects the memory and wireless modules. The cover plate on the left covers the secondary hard drive if the unit has one. Some dv9700s have two hard drives and others do not.

    • 3

      Slide the looped end of the antistatic wrist strap onto your arm and clip the other end to a metal surface.

    • 4

      Remove the screw to the right of the Windows Authenticity label. Slide the DVD drive out of the notebook.

    • 5

      Push outward on the clips that secure the lower memory module until the memory stick pops up. Remove the module and set it aside. Do the same for the upper memory module.

    • 6

      Disconnect the two leads from the upper part of the wireless card module. Release the clips that secure the card and remove the wireless module.

    • 7

      Lift up on the right side of the primary hard drive slightly. Slide the drive to the right and disconnect the ribbon cable. Remove the primary drive from the dv9700 chassis. Do the same for the secondary drive if your dv9700 has one.

    • 8

      Remove all remaining screws on the bottom of the unit, ensuring that you remove the six screws inside the battery bay as well. Flip the dv9700 notebook back over and open the LCD screen.

    • 9

      Insert the tip of the awl or small flathead screwdriver into the space above the top row of keys on the keyboard. Start at the right side of the dv9700 keyboard and work your way to the left as you pry up the cover above the top row of keys gently. Avoid breaking the plastic tabs on the keyboard edge cover.

    • 10

      Remove the three screws above the "Esc," "F4" and "F12" keys on the keyboard. Lift up on the top edge of the keyboard and disconnect the ribbon cable from the motherboard underneath. Remove the keyboard from the dv9700 chassis.

    • 11

      Remove the six screws that secure the motherboard cover plate in the keyboard well. Remove the cover plate and set it aside.

    • 12

      Remove the four screws that secure the thermal cooling assembly. Remove the thermal cooling fan and heatsink and set the assembly aside. Locate the chip with an “NVIDIA” label on it.

    • 13

      Plug the desoldering tool into an electrical socket and allow it to heat up. Ensure that the LCD screen for the dv9700 is open and fully extended until almost flat.

    • 14

      Run the tip of the hot desoldering tool over the pins on one side of the NVIDIA chip. Use the suction cup on the tool to remove hot solder as you heat it. Work slowly but do not hold the tip of the tool too long in one spot, as you risk damaging the motherboard.

    • 15

      Desolder the pins on the other three sides of the chip and remove the heated solder. Remove the NVIDIA chip from the surface of the motherboard carefully after desoldering it.

    • 16

      Use the solder flux to scrub the pin trace areas on the four sides of the spot from which you removed the NVIDIA chip. Scrub the trace pins gently with just enough pressure to break up any remaining solder you were not able to remove with the suction cup.

    • 17

      Use the solder brush to brush away and remaining solder fragments. Use the canned air to blow any dust and solder fragments out of the machine.

    • 18

      Clean the pin traces with cotton swabs and denatured alcohol. Allow the pin traces to dry completely.

    • 19

      Align the new NVIDA chip with the pin traces. Solder the new chip into place. Reassemble the dv9700 by reversing the steps used to dismantle it.

Tips & Warnings

  • HP does not sell the NVIDIA chips individually. To find one, you must search online electronics retailers or purchase a surplus chip from an auction site such as eBay.
