Chapter 8. Removing and replacing a FRU

External CRU statement to customers:
Some problems with your product can be resolved with a replacement part you can install yourself, called
a "Customer Replaceable Unit" or "CRU." Some CRUs are designated as Self-service CRUs and others
are designated as Optional-service CRUs. Installation of Self-service CRUs is your responsibility; you may
request that Lenovo installs an Optional-service CRU according to the warranty service for your product.
Where you are installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement
instructions are shipped with your product and are available from Lenovo at any time upon request. You may
find a list of CRUs in the publications that ship with your product or at http://www.lenovo.com/CRUs. You
may be required to return the defective part that is replaced by the CRU. When return is required: (1) return
instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you
may be charged for the replacement CRU if Lenovo does not receive the defective part within thirty (30) days
of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details.
This chapter presents directions and drawings for use in removing and replacing a FRU. Be sure to observe
the following general rules:
1. Do not try 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 Chapter 7 "FRU replacement notices" on page 45.
3. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Such FRUs are
listed in each FRU replacement section. Remove them in the order in which they are listed.
4. Follow the correct sequence in the steps for removing a FRU, as given in the drawings by the numbers
in square callouts.
5. When turning a screw to replace a FRU, turn it in the direction as given by the arrow in the drawing.
6. When removing a FRU, move it in the direction as given by the arrow in the drawing.
7. To put the new FRU in place, reverse the removal procedure and follow any notes that pertain to
replacement. For information about connecting and arranging internal cables, see Chapter 9 "Locations"
on page 79.
8. When replacing a FRU, use the correct screw(s) 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 interconnecting cables.
Attention: After replacing a 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 by using an
electrostatic discharge (ESD) strap (P/N 6405959).

Before servicing ThinkPad X130e models

Some ThinkPad X130e models you are servicing might have the SIM card that the customer has installed.
If the computer you are servicing has the SIM card, remove it before you start the servicing.
