NOTE: While removing the base cover, on-site technicians must take care to remove the base cover carefully. There are
prying recess points next to the left and right hinges which ease the disassembly procedure. With the help of a plastic
scribe, pry open from the top left side of the base cover, continue working your way around the left and right side of the
base cover, then remove the base cover from the system.
3 Lift the base cover from the computer.
