Einleitung

Follow this guide if you want to replace the motherboard of your HP Envy 17-3070NR. The motherboard connects all parts of the PC together and it is a most complex part of the computer. Unfortunately, with great complexity comes great room for failure. Should any of the components on the motherboard fail, whole motherboard needs to be replaced to fix the issue.

Werkzeuge

Schritt 1

Before you begin taking apart the computer, make sure that it is completely powered off.
Slide the release latch away from the nearest edge.
Slide the back cover off of the computer.

Schritt 2

Remove the six 3.7mm Phillips screws.
Slide the back cover until it clicks, then lift it straight off.

Schritt 3

Remove the four 3.7mm Phillips screws that hold the hard drive onto the computer.
Remove the hard drive by lifting it out of its cavity.
Unplug the hard drive cable that connects it to the main assembly.

Schritt 4

Disconnect the multi-colored battery cable from the main assembly by gently pulling upward on it.

Schritt 5

Remove the two 3.8 mm Torx screws using M8 Torx screwdriver.
Remove the battery by pulling it straight out away from the computer.
It is much easier to use the battery cable to carefully lift the battery off than to try to pry it off with tools.

Has anyone found a place that sources replacement batteries for these? As far as I can gather HP is not supplying this model's battery nor have I been able to source any equivalent after market battery. Looking on forums it seems others have the same problem!

Schritt 6

Remove the four 3.7mm Phillips screws that secure the optical drive to the computer.
Slowly lift the optical drive away from the computer ensuring that you don't put stress on the connecting cable.
Do not fully lift off the optical drive as there is still a cable that connects it to the motherboard.

Schritt 7

Remove Sub Speaker assembly first in order to remove Optical drive. Carefully disconnect speaker connector.

Schritt 8

Carefully disconnect the connecting cable by lifting the white clamp with a Flathead screwdriver and pulling on the blue tab away from connector.

Schritt 9

Unscrew the three 6.5mm Phillips shoulder screws that connect the subwoofer to the computer.
Disconnect the red and black subwoofer cable from the system board by pulling it upwards.
Remove the subwoofer by pulling straight up from the main assembly.

Schritt 10

Press down on both tabs on either side of the top RAM stick.
The RAM will slightly pop out and you will be able to slide it out of it's cavity.
Repeat the same process for the second stick of RAM if needed.

Schritt 11

Unscrew 4.5mm Phillips screw.
Unplug both antenna connectors by carefully pulling them upwards.
During re-assembly make sure to match numbers(1 or 2) on the antenna cable and the wireless card.

Schritt 12

Pull wireless card up and away from you.

Schritt 13

Remove the three 3.6 mm Phillips screws.
Remove the eleven 3.2mm Phillips screws
Three of the 3.2mm Phillips screws are located underneath the black hard drive flap.
Make sure that you keep the screws organized so that you keep track of all of the different sizes and locations.

Schritt 17

Flip the laptop over.
Use a Plastic Opening tool to carefully pry all around the top cover up off of the remaining assembly.
Starting location for prying does not matter as long as you pry all around the frame before lifting it off.
Do not fully lift the top cover because there are cables that will need to be disconnected before removal.

Schritt 18

Gently pull the white connector shown in the picture towards you to disconnect it from the system board.

Schritt 19

Gently pull the black connector towards you to disconnect the top cover from the main assembly.

Remove the three 4.5mm Phillips screws on the fan assembly.
Loosen the seven captive Phillips screws in the ascending numerical order (1-7). Numbers are printed next to each screw on the housing.
Screws will not fully come off the assembly. You need to only loosen them.
Remove the fan assembly from the system board by lifting it straight up.
For reassembly, you will need to clean the old thermal paste off of areas highlighted in yellow as well as matching parts on the fan assembly. Following that, you would need to reapply thermal paste before putting back the fan assembly. Small amount of the size of the rice grain should be enough for each plate.

Schritt 29

Unlock CPU by turning the locking screw 180 degrees counterclockwise using Flathead screwdriver. You will hear a slight click when CPU is fully unlocked.
Carefully lift CPU upwards by holding it from both sides.
It is important to lift CPU straight upward in order to not bend any pins on it.
For reassembly, make sure to put CPU back by matching a small yellow triangle in the corner of CPU to the small triangle imprinted on the CPU socket.
