Screw notices
Loose screws can cause a reliability problem. In Lenovo computers, 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.
• Each one should be used only once.
Do the following when you service this machine:
• Keep the screw kit in your tool bag.
• Always use new screws.
• 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:
•
Logic card to plastic
Turn an additional 180° after the screw head touches the surface of the logic
card:
•
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.
Never use a screw
that you removed. Use a new one. Make sure that all screws are
tightened firmly
.
• Ensure torque screwdrivers are calibrated correctly following country
specifications.
