Screw notices

Loose screws can cause a reliability problem. In the Lenovo computer, this problem is addressed with special nylon-coated screws that have the following characteristics:

They maintain tight connections.

They do not easily come loose, even with shock or vibration.

They are harder to tighten.

Do the following when you service this machine:

Keep the screw kit in your tool bag.

Carefully remove screws for reuse when replacing FRUs.

Use a torque screwdriver if you have one.

Tighten screws as follows:

Plastic to plastic

Turn an additional 90° after the screw head touches the surface of the plastic part:

more than 90°

(Cross-section)

Logic card to plastic

Turn an additional 180° after the screw head touches the surface of the logic card:

more than 180°

(Cross-section)

Torque driver

If you have a torque screwdriver , refer to the “Torque” column for each step.

Make sure that you use the correct screws. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Carefully remove screws for reuse when replacing FRUs. Make sure that all screws are tightened firmly.

Ensure torque screwdrivers are calibrated correctly following country specifications.
