Thank you for that very detailed tutorial. I would like to add however, you forgot to mention to remove the screw holding in the optical drive. You also have the step to remove the 3 screws under the optical drive BEFORE removing the optical drive. The optical drive hides those screws and must be removed to access those screws. You also did not mention you need to remove the 3 screws holding the touchpad in place. That is a necessary step to remove the touchpad.

Furthermore, there were steps listed that were not necessary at all. The hinge screws do not need to be removed (Step 20) and the display does not need to be removed. The power button circuit board (step 21) does not need to be removed. The DC jack (step 18) does not need to be removed, but you do need to unplug it.

As a tech I followed your instructions before I realized that much of it was unnecessary. Since this is the only tutorial I could find for this laptop, I appreciate your work putting this together.
