Screw Identification and Tightening: Dell™ Inspiron™ 3500 Portable Computer
CAUTION: 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.
Where applicable, information about screw lengths is provided with the illustrations.
The Inspiron 3500 portable computer contains many screws of various sizes. 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.
While removing and replacing parts, use a tackle or pill box as a storage device to keep track of the screws. Use the following location template to store the screws
during disassembly.
NOTE: Each removal and replacement procedure lists the type, size, and torque value of screws removed during the procedure. Screw types include
flat head (FLH), flat pan-head (FPH), pan head (PNH), and jack screws.
