Remove the optical drive, and then open the drive. Remove the disk.
With most laptops this is a simple job.
Turn the laptop over on it's top, remove one Philips head screw, pull the optical drive out.
Remove 2 to 4 screws from a cover on the optical drive, and ease the tray open.
With the Inspiron 1318 Notebook PC it is more difficult.
A) Remove the Display Assembly.
(Removal covers removing the Display Assembly as a whole unit, off of the laptop)
B) Remove the Keyboard.
C) Remove the Palm Rest. (Top cover under the Keyboard. Your palms rest on it when you use the touchpad)
D) Remove the Optical Drive
