I have just successfully dismantled this laptop myself tonight, and it did take a while.
How far have you got with it? I take it you have unscrewed every “Visible” screw? Its quite tricky near the end of the process, I could lift 3 corners of the motherboard out but the corner that has the VGA port on was stuck.
Notice that directly opposite the VGA port, there is another, smaller section of PCB that houses two USB ports and the ethernet port. If you can prise the main motherboard upwards slightly, you will see there is a screw you can unscrew. Now remove this smaller board. Underneath where one of the usb ports was (furthest away from the ethernet port) you will see two screws are revealed. Unscrew these and then remove the long silver piece of metal that spans the length of the battery.
Now, that silver peice of metal is only attached by the one screw that you cant see, as its screwed into the motherboard from the other side. Gently push the VGA port and other ports into the casing and also push the copper fins upwards to release it from the plastic housing. I had a lot of trouble with the VGA port as it has some sort of silver strip sticker attached to it.
If you have any problems or need more guidance, please just let me know.
