General safety guidelines

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

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 an ac power cord, always make
sure 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 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.
Attention
Before replacing any CRUs, turn off the computer and wait three to five
minutes to let the computer cool before opening the cover.
