Screw Tightening Information

Loose screws can cause reliability problems. The IBM ThinkPad/WorkPad computer addresses this problem with nylon-coated screws.

Tighten screws as follows:

Plastic to Plastic

Turn an additional 90 degrees after the screw head touches the surface of the plastic part.

 


Logic Card to Plastic

Turn an additional 180 degrees after the screw head touches the surface of the plastic part.

 

Torque screw-drivers can be ordered from:
