Safety Guidelines

Always observe the following precautions to reduce the risk of
injury and property damage.

Service and Upgrades

CAUTION
Do not attempt to service a product yourself unless instructed to do
so by the Customer Support Center or your documentation. Only use
a service provider who is approved to repair your particular product.
Note: Some computer parts can be upgraded or replaced by the
customer. Upgrades typically are referred to as options.
Replacement parts approved for customer installation are
referred to as Customer Replaceable Units, or CRUs.
Lenovo provides documentation with instructions when it
is appropriate for customers to install options or replace
CRUs. You must closely follow all instructions when
installing or replacing parts. The Off state of a power
indicator does not necessarily mean that voltage levels
inside a product are zero. Before you remove the covers
from a product equipped with an ac power cord, always
make sure that the power is turned off and that the
product is unplugged from any power source. For more
