These are some photos taken during dismantling to install a wireless card, antenna and a new keyboard and touchpad.
The procedure is probably simular for other makes & models of laptops.
Step 1:
The HDD is removed first to ensure it isnt damaged. The 2 screws are undone then it is pulled out.
Step 2:
Then the button / hinge cover is removed.

Remove the button panel screws

Finally unclip the button panel
Step 3:
Next the keyboard is removed. First the screws are removed.

Then the keyboard is lifted off. (Carefully unclip the wire)
Step 4:
The screen is then removed. First the wire should be uncliped. To do this its worth removing the Left speaker. The screws are then undone.
Step 5:
The final step is removing the top. To do this remove the screws from underneath.

And the two screws from the back and from the top under the keyboard.
End Result
The laptop in bits !
