Use the following strategy to prevent unnecessary expense for replacing and 
servicing FRUs:
• If you are instructed to replace an FR U, but the replacement does not solve 
the problem, reinstall the original FRU before you continue.
• Some computers have both a processor board and a system board. If you are  instructed to replace either of them, and replacing one of them does not solve 
the problem, reinstall that board,  and then replace the other one.
• If an adapter or a device consists of more than one FRU, any of the FRUs may  be the cause of the error. Before repl acing the adapter or device, remove the 
FRUs one by one to see if the symptoms change. Replace only the FRU that 
changed the symptoms.
Attention:  The setup configuration on the computer you are servicing may have 
been customized. Running Automatic Conf iguration may alter the settings. Note 
the current configuration settings (using  the View Configuration option); then, 
when service has been completed, verify  that those settings remain in effect.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper 
handling can cause damage to those  components, and may cause a system 
malfunction.
Attention:  When handling a system board:
• Do not drop the system board or  apply any excessive force to it.
• Avoid rough handling of any kind.
• Avoid bending the system board and hard pushing to prevent cracking at  each BGA (Ball Grid Array) chipset.

RoHS, The Restriction of Hazardous Substances in Electrical and 
Electronic Equipment Directive (2002/95/EC) is a European Union legal 
requirement affecting the global elec tronics industry. RoHS requirements 
must be implemented on Lenovo products placed on the market after June 
2006. Products on the market before June 2006 are not required to have 
RoHS compliant parts. If the orig inal FRU parts are non-compliant, 
replacement parts can also be non-compliant. In all cases if the original 
FRU parts are RoHS compliant, the replacement part must also be RoHS 
compliant.
Note:  RoHS and non-RoHS FRU part numbers  with the same fit and function are 
identified with unique FRU part numbers.
Lenovo plans to transit to RoHS compliance well before the implementation date 
and expects its suppliers to be ready  to support Lenovo’s requirements and 
schedule in the EU. Products sold in 2005 and 2006 will contain some RoHS 
compliant FRUs. The followi ng statement pertains to these products and any 
product Lenovo produces cont aining RoHS compliant FRUs.
RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS 
implementation date, failed RoHS complian t parts must always be replaced with 
RoHS compliant ones, so only the FRUs identified as compliant in the system 
HMM or direct substitutions  for those FRUs may be used.
Note:  A direct substitution is a part with  a different FRU part number that is 
automatically shipped by th e distribution center at the time of the order.

Before you go to the checkout, make sure to read the following important notes:
General checkout
Important notes:
Only certified trained personnel can service the computer.
 Before replacing any FRU, read the entire page on removing and 
replacing FRUs.
 When you replace FRUs, use new nylon-coated screws.
 Be extremely careful during such write operations as copying, 
saving, or formatting. Drives in the computer that you are servicing 
sequence might have been altered. If you select an incorrect drive, data 
or programs might be overwritten.
 Replace an FRU only with another FRU of the correct model.  When 
you replace an FRU, make sure that  the machine model and the FRU part 
number are correct by referring to the FRU parts list.  
 An FRU should not be replaced just because of a single, 
unreproducible failure.  Single failures can occur for a variety of reasons 
that have nothing to do with a hardwa re defect, such as cosmic radiation, 
electrostatic discharge, or software errors. Consider replacing an FRU 
only when a problem recurs. If you  suspect that an FRU is defective, 
clear the error logs and run the test ag ain. If the error does not recur, do 
not replace the FRU.
 Be careful not to replace a nondefective FRU.

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 proble m. In Lenovo computers, this problem 
is addressed with special nylon-coat ed 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:
 To r q u e  d r i v e r
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 cali brated correctly following country 
specifications.
