„ Service and Upgrades
Attention:
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 information on CRUs, see “Appendix B. Customer Replaceable Units
(CRUs)” on page 101. If you have any questions or concerns, contact the
Customer Support Center.
Although there are no moving parts in your computer after the power cord
has been disconnected, the following warnings are required for your
safety.
Danger:
Hazardous moving parts. Keep fingers and other body parts away.
