Lenovo Thinkpad Advance Ultrabay Battery II Handbuch Seite 51

If your Service Provider determines that it is unable to either repair or
replace your product, your sole remedy is to return the product to your
place of purchase or to Lenovo and your purchase price will be
refunded.
Exchange of a Product or Part
When the warranty service involves the exchange of a product or part,
the item your Service Provider replaces becomes Lenovo's property and
the replacement becomes yours. All removed items must be genuine
and unaltered. The replacement may not be new, but will be in good
working order and at least functionally equivalent to the item replaced.
The replacement assumes the warranty status of the replaced item.
Before your Service Provider exchanges a product or part, you agree to:
1. remove all features, parts, options, alterations, and attachments not
under warranty service;
2. ensure that the product is free of any legal obligations or restrictions
that prevent its exchange; and
3. obtain authorization from the owner to have your Service Provider
service a product that you do not own.
Your Additional Responsibilities
Where applicable, before service is provided, you agree to:
1. follow the service request procedures that your Service Provider
specifies;
2. backup or secure all programs and data contained in the product;
3. provide your Service Provider with all system keys or passwords
and sufficient, free, and safe access to your facilities to permit the
terms of this warranty to be fulfilled; and
4. ensure that all information about identified or identifiable
individuals ("Personal Data") is deleted from the product or that,
with respect to any remaining Personal Data you did not delete,
you are in compliance with all applicable laws.
