In the following guide I’ll be taking apart a Gateway NX570X laptop. I think my disassembly instructions will work for other Gateway laptops in the NX570 line too. Please let me know if you have a different Gateway laptop and this guide works for you, you can mention your model in the comments below.
The laptop I’m fixing stopped charging the battery even though the AC adapter works properly and outputs correct voltage. I tested the adapter with a voltmeter. Actually, it’s charging the battery but only intermittently, when the AC adapter pushed in firmly. In order to charge the battery I have to adjust the AC adapter plug inside the power socket on the back of the laptop. Apparently, there is a problem with the power socket (aka power jack) and it has to be replaced or resoldered. OK, let’s take this lappy apart. I’ll be removing the system board so I can access and repair the power jack.
Turn off the laptop, unplug the AC adapter and remove the battery.
Remove seven screws (yellow circles) securing the memory cover.
Remove one screw (yellow circle) securing the keyboard. There are two more keyboard screws under the memory cover. You can see them in the step 5.
Remove one screw (orange circle) securing the Wi-Fi card cover.
Remove two screws (red circle) securing the hard drive. In order to disconnect the hard drive from the motherboard, you’ll have to slide the hard drive assembly to the left. Remove the hard drive assembly from the laptop.
Disconnect two antenna cables from the wireless card, simply unsnap them from the card using your fingers. Remove one screw securing the wireless card and remove the card.
Remove both memory modules.
Loosen four screws securing the heat sink assembly (red circles).
Carefully lift up the heat sink assembly from the laptop. The cooling fan is attached to the motherboard. Unplug this cable from the motherboard.
Remove one screw securing the CD/DVD drive. Push the drive to the left and remove it from the laptop.
Remove all screws from the bottom of the laptop. Two screws marked with green circles are securing the keyboard.
If you are replacing the keyboard, you simply remove one green screw in the step 1 and two green screws in the step 5 and then proceed to steps 7,8,9,10.
Remove two screws from the hinge cover.
Start removing the hinge cover with a small flathead screwdriver and continue removing it with your fingers.
Remove the hinge cover.
Lift up the keyboard as it shown on the picture below and place it upside down on the palm rest.
Unlock connector on the system board. Release the cable and remove the keyboard.
Release the wireless card antenna cables.
Unplug LCD cable from the system board.
Remove two screws from each display hinge.
Carefully lift up and remove the LCD assembly.
Remove four screws securing the top cover.
Unplug the touch pad cable from the system board.
Lift up and remove the top cover assembly.
Remove five screws securing the motherboard.
Unplug the speaker cable (left) and the Bluetooth card cable (right) from the system board.
Start removing the system board from the left side.
You’ll have to disconnect one more cable shown on the picture below.
Finally, the system board has been removed.
Now you can access and repair the power jack. You can use these power jack replacement instructions.
When I was removing the power jack from the system board, it came out with the internal sleeve attached to the “+” connector. This sleeve connects traces on both sides of the system board and normally, when you unsolder the power jack, it stays inside the hole.
Now I’ll have to make a modification so traces on both sides of the system board are connected. I’ll have to connect traces with a cable.
