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.• 
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: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. 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 32
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 a n y   o f   t h e   n o t e s   t h a t   p e r t a i n   t o   r e p l a c e m e n t .   F o r   i n f o r m a t i o n   a b o u t connecting and arranging internal cables, see “Locations” on page 69.
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:  T h e   s y s t e m   b o a r d   i s   s e n s i t i v e   t o ,   a n d   c a n   b e   d a m a g e d   b y, 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.
Notes:
The  illustrations  used  in  this  section  are  of  the  Lenovo  G570,  unless • otherwise stated.
The following procedures about removing and replacing FRUs are the same • for the G470&G475&G570&G575.
