Sketch a diagram of the bottom of the laptop. Make sure to mark all of the screw holes.

Note: This step is optional, but it is highly recommended. The diagram is used exclusively for keeping track of the screws on the bottom of the laptop.

Note: The three screws in the blue box are under the hard drive and are not immediately visible. The three screws in the red box are under the CD drive and are also not visible at this point in disassembly.
