Windows label
Your computer might have a Windows 10 Genuine Microsoft label affixed to its cover depending on the
following factors:
• Your geographic location
• Edition of Windows 10 that is preinstalled
Go to
https://www.microsoft.com/en-us/howtotell/Hardware.aspx for illustrations of the various types of
Genuine Microsoft labels.
• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 10.
• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 10 Pro.
The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at:
https://www.microsoft.com/en-us/howtotell/default.aspx
There are no external, visual indicators of the Product ID or Windows version for which the computer is
licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a Windows 10 product is
installed, the installation program checks the computer firmware for a valid, matching Product ID to complete
the activation.
In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.

hard disk password to access files and applications on the storage drive.
• Master hard disk password + User hard disk password
The master hard disk password is set and used by a system administrator. It enables the administrator to
access any storage drive in a system or any computer connected in the same network. The administrator
can also assign a user hard disk password for each computer in the network. The user of the computer
can change the user hard disk password as desired, but only the administrator can remove the user hard
disk password.
When prompted to enter a hard disk password, press F1 to switch between the master hard disk password

Chapter 6. CRU replacement
What are CRUs
Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. The
computers contain the following types of CRUs:
• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by
trained service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill
level. Trained service technicians can also provide service to install or replace the parts under the type of
warranty designated for the customer’s machine.
If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement
instructions are shipped with your product and are available from Lenovo at any time upon request. You
might be required to return the defective part that is replaced by the CRU. When return is required: (1) return
instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you
might be charged for the replacement CRU if Lenovo does not receive the defective CRU within thirty (30)
days of your receipt of the replacement CRU. For full details, see the Lenovo Limited Warranty
documentation at

away, but rather put in the established collection systems for reclaiming these end of life products.
Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of life
EEE as unsorted municipal waste, but use the collection framework available to them for the return, recycle,
and recovery of WEEE and to minimize any potential effects of EEE on the environment and human health
due to the presence of hazardous substances. Lenovo electrical and electronic equipment (EEE) may contain
parts and components, which at end-of-life might qualify as hazardous waste.
EEE and waste electrical and electronic equipment (WEEE) can be delivered free of charge to the place of
