Safety instructions
Use the following safety guidelines to help protect your computer from potential damage and
to help to ensure your personal safety. Unless otherwise noted, each procedure included in this
document assumes that you have read the safety information that shipped with your
computer.
WARNING: Disconnect all power sources before opening the computer cover or
panels. After you finish working inside the computer, replace all covers, panels, and
screws before connecting to the power source.
CAUTION: Some repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and support
team. Damage due to servicing that is not authorized by Compulab is not covered by your
warranty. Read and follow the safety instructions that came with the product.
CAUTION: To avoid electrostatic discharge and prevent internal components damage
from electrostatic discharge when touching computer or its parts, ground yourself by
using a wrist grounding strap or by periodically touching an unpainted metal surface, such
as a connector on the back of the computer.
CAUTION: Handle components and cards with care. Do not touch the components or
contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a
component such as a processor by its edges, not by its pins.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not
on the cable itself. Some cables have connectors with locking tabs; if you are
disconnecting this type of cable, press in on the locking tabs before you disconnect the
cable. As you pull connectors apart, keep them evenly aligned to avoid bending any
connector pins. Also, before you connect a cable, ensure that both connectors are
correctly oriented and aligned.
