FRU removals and replacements
This section contains information about removals and
replacements.
Do not damage any parts. Only certified and trained
personnel should service the computer.
The arrows in this section show the direction of move-
ment to remove a FRU, or to turn a screw to release
the FRU. The arrows are marked in numeric order, in
square callout, to show the correct sequence of
removal.
Any FRUs that must be removed before removing the
failing FRU are listed at the top of the page.
To replace a FRU, reverse the removal procedure
and follow any notes that pertain to replacement. See
“Locations” on page 40 for internal cable connections
and arrangement information.
When replacing a FRU, use the correct screw size, as
shown in the procedure.
Safety Notice 1
Translations in "Safety Notices (Multilingual Trans-
lations)" section: Before the computer is powered-on
after FRU replacement, make sure all screws, springs,
or other small parts are in place and are not left loose
inside the computer. Verify this by shaking the com-
puter and listening for rattling sounds. Metallic parts or
metal flakes can cause electrical shorts.
Safety Notice 3
Translations in "Safety Notices (Multilingual Trans-
lations)" section: The battery pack contains small
amounts of nickel. Do not disassemble it, throw it into
fire or water, or short-circuit it. Dispose of the battery
pack as required by local ordinances or regulations.
Use only the battery in the appropriate parts listing
when replacing the battery pack. Use of an incorrect
battery can result in ignition or explosion of the
battery.
Safety Notice 8
Translations in "Safety Notices (Multilingual Trans-
lations)" section: Before removing any FRU, power-off
the computer, unplug all power cords from electrical
outlets, remove the battery pack, then disconnect any
interconnecting cables.
Attention: The system board is sensitive and can be
damaged by electronic discharge. Establish personal
grounding by touching a ground point with one hand before
