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 “T orque” 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.

 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.
