Limited onsite service systems
are
designed to be repaired during the ap-
plicable warranty period primarily with
customer-replaceable parts provided
by Lenovo. Lenovo will only send a
technician onsite to perform a repair if
(a) remote telephone diagnosis and/or
customer part replacement are unable
to resolve the problem, or (b) the part is
one of the few designated by Lenovo for
onsite replacement. For a list of onsite
replaceable parts, contact Lenovo. In
the United States call 1-800-426-7378.
Support unrelated to a warranty issue
may be subject to additional charges.
Lenovo onsite repair (LOR), 8 am to 5
pm, Monday through Friday coverage

802.11b, and 802.11g respectively. An
adapter with 11a/b, 11b/g, or 11a/b/g can
communicate on either/any of these
