HP Touchsmart IQ775 - Disassembly Procedures.
Start at the Back of the LCD part:
1. Looking at the left side of the body back cover,
remove the screw at the top of the power cord socket.
Remove the screw at the top of "IR out". Then slide the body top cover towards you.
2. Disconnect the DVD cable, then pull-up the left black lock to release the DVD drive.
3. Looking the neck of the LCD, there is a slide switch to release
the cover of the HD. It's located above the OEM key sticker.
Press it down then the back cover will release.
4. Remove the 4 screws, 2 each side of the ports (usb, Ethernet/connections) side.
5. Remove the 3 screws of the CPU fan.
6. Remove the 2 screws at the edge side of the motherboard.
7. Remove the 2 screws at the middle part of the motherboard.
8. Remove the 3 screws of the metal face upper plate.
One the right middle part and the other one in the middle is a long (1.5")
and the other is located at the edge of the left of the power supply.
Next is the front of the LCD part:
9. Remove the plastic cover where the OEM sticker located.
You can use flat screw driver and pry it around. There is no screw to this plastic.
10. Remove the shiny metal by removing the 6 screws.
Note use the 3" tall Philip screw driver for this part because of the space so limited.
11. To remove the plastic covering the buttom dome part is tricky.
Start at the back, release the 3 hooks type from the metal body frame and
press down at least half-inch downward. Then wiggle and push it the right
side and remove it towards you, assuming you are facing the front of the LCD.
12. Now the SECRET PART, there are 2 silver screws hiding under the sticker.
Open the door of the Connectivity. Next peel-off the sticker
saying (L) Audio (R) input. You'll going to see a silver screw. Do the same
at the other side of USB 2.0 and remove the screw.
Making diagram and labeling of cables:
Note I drew and labeled each cables by using 3M Scoth's Tape for
labeling and paper and pencil for their specific locations.
This is very important. I used big needle in releasing the Bluetooth wire.
Pry it to the side and be patient. Don't pull the wire it is very fragile.
13. Note: the plastic cover for the front face (DVD's play, pause, eject)
is not suppose to remove because it is screwed together with the metal frame.
14. If you are facing the front of the LCD, use your left hand and
lift the metal frame starting at the back. Then the right hand at the
other end of the metal frame. Lift it about 1" and wiggle it. Then push
it towards you. It should release and then remove it. Pull it slowly and
you'll going to see lot of cables. This is the part to draw the locations
and labeling of each cable before removing them.
15. Remove the 2 screws from left and right edge of the motherboard.
The right edge screw is hidden under the LED lights' wire. Just make way and remove it.
16. Removing the power supply's molex connection is tricky.
I used flat screw drive to separate it from the motherboard.
17. Now twist around the computer and facing the Back part
of the LCD part. Note there is a PCI WinTV adapter connection under the motherboard.
18. Lift the motherboard straight upward by gently wiggling it.
There will be a little struggle it should release after a while.
Aside from the PCI connection, there is a thermal sticky on the Intel chip.
19. Done. And the rest is easy.
Note: I replaced 16 pieces of bad, leaking and defective capacitors. These are the:
7 pcs - 6.3v 820microfarad
6 pcs - 4.0v 680microfarad
1 pc - 16v 100microfarad
2 pc - 6.3v 330microfarad
Note: I also improved the heatsink of the GPU (graphics card).
By placing a 2" x 1" copper by connecting it the metal frame of
the DVD drive's metal. The reason was because the temperature
around the GPU was above 70 degree Centigrade. By connecting the
piece of copper thru the neck of the heat sink GPU together with
metal frame the temperature dropped by at 10 degrees.

Hi. If this is the product number of your computer (GS275AA). Then the video card is on board. Meaning it is built in to the motherboard and you cannot replace that one.

Replacing the card should be easy. You should just remove the cover at the top by removing the screws holding it in place. The card should be inserted into the PIC/PCI-E slot on the motherboard.
