FRU replacement notices
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.
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 screwdri\
ver, 
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.

Removing and replacing an FRU
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 31.
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 \
55.
8.  When replacing an FRU, use the correct screw as shown in the procedures.
 DANGER
Before	 removing	 any	FRU,	 turn	off	the	 computer,	 unplug	all	power	 cords	from	
electrical	 outlets,	remove	 the	battery	 pack,	and	then	 disconnect	 any	of	the 	
interconnecting	cables.
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.
