This section contains information about removals and
replacements.
Do not damage any FRUs. Only certified and trained
personnel should service the computer.
The arrows in the “Removals and Replacements”
section show the direction of movement to remove a
FRU, or to turn a screw to release the FRU. The
arrows are marked in numeric order, in square
callouts, to show the correct sequence of removal.
When other FRUs must be removed before the failing
FRU is removed, they are listed in that order.
To replace a FRU, reverse the removal procedure
and follow any notes that pertain to replacement.
See “Locations” for internal cable connections and
arrangement information.
When replacing a FRU, use the correct screw size as
shown in the procedures.
Safety Notice 1: Translation on page 5
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 computer
and listening for rattling sounds. Metallic parts or
metal flakes can cause electrical short circuits.

The lithium battery can cause a fire, explosion, or
severe burn. Do not recharge it, remove its polarized
connector, disassemble it, heat it above 100°C
(212°F), incinerate it, or expose its cell contents to
water. Dispose of the battery as required by local
ordinances or regulations. Use only the battery in the
appropriate parts listing. Use of an incorrect battery
can result in ignition or explosion of the battery.
Safety Notice 8: Translation on page 11
Before removing any FRU, power-off the computer,
unplug all power cords from electrical outlets, remove
the battery pack, and then disconnect any
interconnecting cables.
Attention: The system board is sensitive to, and can be
damaged by, electrostatic discharge. Establish personal
grounding by touching a ground point with one hand before
touching these units. Use an electrostatic discharge (ESD)
strap (P/N 6405959) to establish personal grounding.
