Removing and replacing a FRU
This section 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 “FRU replacement notices” on page 51.
3. Begin by removing any FRUs that have to be removed before the failing FRU.
Any 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 for removing the 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 the 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 “Locations” on page 103.
8. When replacing a FRU, use the correct screw as shown in the procedures.
DANGER
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 removing any FRU, turn off the computer, unplug all power cords from
electrical outlets, remove the battery pack, and then disconnect any interconnecting
cables.
