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 laptop.
You can use this guide for one of the following projects:
1. Removing and replacing the keyboard.
2. Removing and replacing the cooling fan.
3. Removing and replacing the CMOS battery.
4. Removing, replacing or upgrading memory modules in the internal or external slots.
4. Removing and replacing the hard drive and CD/DVD optical drive.

STEP 1.
Turn off the laptop, unplug the AC power adapter and remove the battery.
Remove two screws found in the battery compartment. These screws securing the keyboard cover.
STEP 2.
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 on the laptop so it doesn’t get lost.
STEP 3.
Start removing the keyboard/hinge cover from the laptop.
Be careful because the power button board and finger scan device are attached to the cover and connected to the motherboard via a flat ribbon cable.
STEP 4.
Remove the keyboard/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 for your convenience.
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).
STEP 5.
Remove three screws securing the keyboard.
There are two ribbon cables connecting the keyboard to the motherboard:
1. The pointing stick cable.
2. The keyboard cable.
STEP 6.
Move the keyboard towards the LCD screen so you can access the pointing stick cable.
STEP 7.
Unlock the connector and release the cable.
STEP 8.
Carefully turn the keyboard upside down and access the cable connector underneath. The locking clip must stat attached to the connector base.
STEP 9.
Unlock the connector and release the cable. The locking clip must stat attached to the connector base.
STEP 10.
Remove all screws securing the aluminum cover.
STEP 11.
Remove the cover.
Under the cover you get access to the cooling fan, memory module in the internal slot, CMOS battery.
STEP 12.
Remove/loosen five screws securing the heat sink and cooling fan assembly.
Disconnect the cooling fan cable from the power board.
You’ll have to disconnect the video cable from the motherboard because the fan cable routed under the video cable harness.
STEP 13.
Remove the heat sink and cooling fan assembly.
STEP 14.
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 of the laptop.

gerard,
Not sure what you are asking about. Are you talking about the power socket inside the laptop? The place where you plug the AC adapter?
If the power jack is loose, you’ll have to disassemble the laptop and take a closer look at the jack. In most cases the jack can be replaced.
If it’s soldered to the motherboard, you’ll have to resolder it.

This is a great guide. I have a question about the monitor. I replaced the monitor on the computer I have, same model BX760.
There was a small rectangular magnet on the right side of the monitor. What is it for if anything? Strange thing too… I can’t get the computer to standby or hibernate when the cover is closed.
Is the magnet related and if not what do you think it could be?
Thanks in advance

Michael,
Yes, it’s related.
Your laptop has a magnetic lid close switch. The switch is located somewhere under the laptop top cover.
When the display is closed, the magnet activates the switch and the laptop goes into standby or hibernation mode.
If you removed the magnet, you’ll have to install it back into the display. This will fix standby/hibernation issue.

Dear Laptop Tech
You are the best!!
I actually tried to put the magnet back before with no luck at all. I was within about an inch of getting into the right position when I actually installed the new monitor and never knew it. I did find out where to position it and now it works perfectly!
Thanks again!!!!!
