This section presents notices related to removing and replacing parts. Read this 
section carefully before replacing any FRU.
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.
 Each one should be used only once.
Do the following when you service this machine:
 Keep the screw kit in your tool bag.
 Remove screws carefully for reuse.
 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.

This section presents exploded figures with the instructions to indicate how to 
remove and replace the FRU. Make sure to observe the following general rules:
1. Do not attempt to service any computer unless you have been trained and 
certified. An untrained person runs the risk of damaging parts.
2. Before replacing any FRU, review “FRU replacement notices” on page 34.
3. Begin by removing any FRUs that have to be removed before the failing FRU. 
Any of such FRUs are listed at the top of the page. Remove them in the order 
in which they are listed.
4. Follow the correct sequence in the steps to remove the FRU, as given in the 
figures by the numbers in square callouts.
5. When turning a screw to replace an FRU, turn it in the direction as given by 
the arrow in the figure.
6. When removing the FRU, move it in the direction as given by the arrow in the 
figure.
7. To put the new FRU in place, reverse the removal procedures and follow any 
of the notes that pertain to replacement. For information about connecting 
and arranging internal cables, see “Locations” on page 77.
8. When replacing an FRU, use the correct screw as shown in the procedures.
Attention: After replacing an FRU, do not turn on the computer until you have 
made sure that all screws, springs, and other small parts are in place and none 
are loose inside the computer. Verify this by shaking the computer gently and 
listening for rattling sounds. Metallic parts or metal flakes can cause electrical 
short circuits.
Attention: The system board is sensitive to, and can be damaged by, electrostatic 
discharge. Before touching it, establish personal grounding by touching a 
ground point with one hand or using an electrostatic discharge (ESD) strap 
(P/N 6405959) to remove potential shock reasons.
Note: The illustrations used in this section are of the Lenovo G500, unless 
otherwise stated.
