This section presents notices related to removing and replacing parts. Read this section
carefully before replacing any FRU.
About screws
Loose screws can cause a reliability problem. In Lenovo computers, this problem is addressed
with special nylon-coated 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.
Refer to the table on page 11 for a list of screw specifications.
FRU Replacement Notices
Note: Never re-use a screw that you removed. Use a new one. Make sure that all screws are
tightened firmly.

Removing and Replacing FRUs
More than 180o
Danger: Before removing any FRU, turn off the computer, unplug all power cords
from electrical outlets, remove the battery pack, and disconnect any of the
interconnecting cables.
Attention: After replacing an FRU, do not turn on the computer until you have made sure
that all screws, springs, and other small parts are in place and that none of them is loose
inside the computer. Verify this by gently shaking the computer and listening for rattling
sounds. Metallic parts or metal flakes can cause electrical short circuits.
The system board is sensitive to, and can be damaged by, electrostatic discharge. Before
touching it, establish a personal grounding by touching a ground point with one hand or by
using an electrostatic discharge (ESD) strap (P/N 6405959) to eliminate the possibility of
electrical shock.
