Service and upgrades
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 a power cord, always ensure
that the power is turned off and that the product is unplugged from any power source. If you have any
questions or concerns, contact the Customer Support Center.
Although there are no moving parts in the computer after the power cord has been disconnected, the
following warnings are required for your safety.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
