Customer Replacement Units
(CRUs)
are designed to be replaced by custom-
ers during the applicable warranty pe-
riod. Lenovo will send a technician onsite
to perform a repair if remote telephone
diagnosis does not isolate the problem,
if customer replaceable parts are unable
to resolve the problem, or at the request
of the customer. For a list of customer
replaceable parts, contact Lenovo. Sup-
port unrelated to a warranty issue may
be subject to additional charges.
