Dear user,
Thanks for purchasing Lenovo notebook! Before using this product,

We are most honored to have you as our customer. In order to make sure

User Guide for you. This manual has been made very simple and
comprehensive. In this manual, you can get information on the system

adjustment. In this case, this might lead to an inconsistency in the actual
makeup of the equipment to that of the information stated in the manual,
but it will not substantially affect your use.
Thanks for your cooperation!

Explanation of hard disk capacity
Dear user,
While using your computer, you may find that the nominal hard disk
capacity indicated is somewhat different from the disk capacity
displayed by the operating system. For example, a nominal 40GB hard
disk will appear as less than 40GB in the operating system. This
discrepancy is not an error in hard disk installation nor any other
problem, but a normal phenomenon of computers. This phenomenon is
primarily due to the following reasons:
I. Different standards used by the manufacturer and operating
system when calculating hard disk capacity
Hard disk manufacturers use a radix of 1000, i.e., 1G = 1,000MB, 1MB =
1,000KB, 1KB = 1,000 bytes. However, when identifying hard disk capacity,
operating systems use a radix of 1024, i.e., 1GB = 1,024MB, 1MB = 1,024KB,
1KB = 1,024 bytes. The standard adopted by your computer is that of the
hard disk manufacturers. Since the standards adopted by the hard disk
manufacturer and operating system are different, the hard disk capacity
displayed by the operating system will be different from the nominal hard
disk capacity.
For example, if the hard disk is nominally X G, even when it is completely
empty, the capacity displayed by the operating system will be:
X × 1000 × 1000 × 1000/ (1024 × 1024 × 1024) ≈X × 0.931 G

In addition, if a portion of the hard disk space has been used for some
specific purpose, then the capacity indicated by the operating system will
be even less than X × 0.931 G.
II. A portion of the hard disk space is used for specific purposes
Lenovo computers may come with preinstalled OneKey Rescue System, so
the hard disk has a special portion partitioned before delivery, which is
used to store hard disk mirror and OneKey Rescue System program files.
The size of the reserved space for this partition varies according to the
model, operating system and software of the computer. For the sake of
safety, this partition is not apparent, which is commonly referred to as a
“hidden partition”.
In addition, after the hard disk is partitioned or formatted, the system will
assign a certain amount of hard disk space for the system files.
For the above reasons, the available hard disk space indicated by the
operating system is always less than the computer’s nominal hard disk
capacity.
