for the product starts on the original date of purchase as shown on your sales receipt or invoice or
as may be otherwise specified by Lenovo. The warranty period and type of warranty service that

Part 3 - Warranty Service Information
" below. This
warranty only applies to products in the country or region of purchase.
THIS WARRANTY IS YOUR EXCLUSIVE WARRANTY AND REPLACES ALL OTHER
WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE. AS SOME STATES OR JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OF EXPRESS OR IMPLIED WARRANTIES, THE ABOVE EXCLUSION MAY NOT

What Your Service Provider Will Do to Correct Problems
When you contact a Service Provider, you must follow the specified problem determination and
resolution procedures.
The Service Provider will attempt to diagnose and resolve your problem by telephone, e-mail or
remote assistance. The Service Provider may direct you to download and install designated
software updates.
Some problems may be resolved with a replacement part that you install yourself called a
"Customer Replaceable Unit" or "CRU." If so, the Service Provider will ship the CRU to you for you
to install.
If your problem cannot be resolved over the telephone; through the application of software updates
or the installation of a CRU, the Service Provider will arrange for service under the type of
warranty service designated for the product under "
Part 3 - Warranty Service Information
" below.
If the Service Provider determines that it is unable to repair your product, the Service Provider will
replace it with one that is at least functionally equivalent.
If the Service Provider determines that it is unable to either repair or replace your product, your
sole remedy under this Limited Warranty is to return the product to your place of purchase or to
Lenovo for a refund of your purchase price.
Replacement Products and Parts
When warranty service involves the replacement of a product or part, the replaced product or part
becomes Lenovo's property and the replacement product or part becomes your property. Only
unaltered Lenovo products and parts are eligible for replacement. The replacement product or part
provided by Lenovo may not be new, but it will be in good working order and at least functionally
equivalent to the original product or part. The replacement product or part shall be warranted for
the balance of the period remaining on the original product.

tools. Installation of Self-service CRUs is your responsibility. You may request that a Service
Provider install Optional-service CRUs under one of the other types of warranty service
designated for your product. An optional service offering may be available for purchase from a
Service Provider or Lenovo under which Self-service CRUs would be installed for you. You may
find a list of CRUs and their designation in the publication that was shipped with your product
or at www.lenovo.com/CRUs. The requirement to return a defective CRU, if any, will be
specified in the instructions shipped with a replacement CRU. When return is required: 1) return
instructions, a prepaid return shipping label, and a container will be included with the
replacement CRU; and 2) you may be charged for the replacement CRU if the Service Provider
does not receive the defective CRU from you within thirty (30) days of your receipt of the

Connecting USB devices
Your computer comes with two USB ports compatible with USB devices.
The first time you plug a USB device into a particular USB port on your computer, Windows
automatically installs a driver for that device. After the driver has been installed, you can
disconnect and reconnect the device without performing any additional steps.
Before disconnecting a USB storage device, make sure your computer has finished transferring
data by that device. Click the Safely Remove Hardware icon in the notification area of Windows
to remove the device before disconnecting.
Note: Typically, Windows detects a new device after connecting it, and then installs the driver
automatically. However, some devices may require you to install the driver before connecting.
Check the documentation provided by the device’s manufacturer before connecting the device.
Note: If your USB device uses a power cord, connect the device to a power source before connecting it.
Otherwise, the device may not be recognized.
