In the following guide I explain how to disassemble a Sony Vaio VGN-BX series laptop.
In my case, I’m working with a Sony Vaio VGN-BX760 model.
Turn off the computer, unplug the AC power adapter and remove the battery.
Remove two screws found in the battery compartment. These screws securing the keyboard cover.
Remove two rubber screw seals. You’ll find two screws hidden under those seals.
You can remove the screw seal with a sharp object. The bottom part of the seal is sticky. Glue the seal somewhere so it doesn’t get lost.
Start removing the hinge cover from the top cover.
Be careful because the power button board and finger scan device are attached to the cover and connected to the motherboard.
Remove the hinge cover.
Now you can access the ribbon cable and disconnect it from the motherboard.
It might be not necessary to disconnect this cable, simply move the cover aside and secure it somehow. I’m showing how to disconnect the cable just in case if you have to.
In order to disconnect the connector you’ll have to lift up the locking clip about 2 millimeters. After that you can pull the cable from the connector.
The locking clip (dark brown) must stat attached to the connector base (white).
Remove three screws located above the function keys.
There are two ribbon cables connecting the keyboard to the motherboard:
1. The pointing stick cable.
2. The keyboard cable.
Move the keyboard towards the display so you can access the pointing stick cable.
Unlock the connector and release the cable.
Carefully turn the keyboard upside down and access the cable connector underneath. The locking clip must stat attached to the connector base.
Unlock the connector and release the cable. The locking clip must stat attached to the connector base.
Now you can remove the keyboard completely.
Remove all screws securing the aluminum cover.
Remove the cover.
Under the cover you get access to the cooling fan, memory module in the internal slot, CMOS battery.
Remove/loosen five screws securing the heat sink and cooling fan assembly.
Disconnect the cooling fan cable.
You’ll have to disconnect the video cable from the motherboard because the fan cable routed under the video cable harness.
Remove the heat sink and cooling fan assembly.
Remove the memory module from the internal slot.
Another memory module, hard drive and optical CD/DVD drive can be access and removed from the bottom.
