Screw Identification and Tightening

Be careful not to scratch the computer plastic case by allowing screws to get between the disassembly surface and the plastic case. Dell suggests
a soft padded work surface.

Your computer contains many screws of various sizes. To help keep track of the screws, use a tackle or pill box as a storage device. Use Table 1
as a location template to store the screws during disassembly.

NOTICE: The correct-length screw must be used when reinstalling a screw. Otherwise, hardware damage could result. Make sure
that the screw is properly aligned with its corresponding hole, and avoid overtightening.

NOTICE: During the removal and replacement procedures, you will see Kapton tape in many places on the computer. When
reinstalling or replacing parts, be sure to replace the Kapton tape correctly to retain the electrical protection and noise reduction
the tape provides.
