ThinkPlus Services: These services
are available for machines normally
used for business, professional, or trade
purposes, rather than personal, family,
or household purposes. Not all machine
types and models are covered. Service
period begins with the equipment date
of purchase. Service must be purchased
during the original limited product war-
ranty period. Service levels are response
time objectives and are not guarantees.
If the machine problem turns out to be a
Customer Replaceable Unit (CRU), a part
will be express shipped to you for quick
replacement. Onsite 24x7x2-hour service
is not available in all locations. For Think-
Pad notebooks requiring LCD or other
component replacement, Lenovo may
choose to perform service at the depot
repair center. Calls must be received by
5 pm local time in order to qualify for
Next Business Day service. P&L means
parts and labor. P/U means pick-up.
See ThinkPlus terms and conditions for
complete details and restrictions.

credit and tenure restrictions and addi-
tional charges may apply to international

party software, additional hardware, and/

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
excluding holidays, next business day

Based on IEEE 802.11a and 802.11b. A
customer can not upgrade to a different
wireless Mini PCI adapter due to FCC
regulations. Security screws
prevent removal of this adapter. This wire-
less LAN product has been designed
to permit legal operation world-wide in
regions which it is approved. This product
has been tested and certifi ed to be
interoperable by the Wireless Ethernet
Compatibility Alliance and is authorized
to carry the Wi-Fi logo.

The IEEE 802.11n specifi cation
(MIMO) has been fi nalized and is
currently in IEEE 802. 1 1n-2009 release.
The maximum speed depends on the
access point device and the number of
integrated antenna used for connection.
An adapter with 11a/b, 11a/b/g, 11b/g/n, or
11a/b/g/n can communicate on any of its
supported formats.

Measures only maximum data transfer
rate, not application performance. Many
factors affect application performance.
