Orientation: the bottom of the laptop facing up, hinge on the opposite side from you.
Be careful if you want to open up the screen after undoing the top left corner screw. This is the only screw on this side attaching the hinge to the baseplate, so if it's removed, the hinge might pry up the corner (upon opening the laptop).
This can also aid in creating the first gap where you can insert a prytool.
