Explanation of Hard Disk Capacity
Dear user,
While using your computer, you may discover 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
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 come with preinstalled OneKey Recovery software, so
the hard disk has a special portion partitioned before delivery, which is
used to store hard disk mirror and OneKey Recovery 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 evident, which is commonly referred to as a “hidden
partition”. It is invisible in the operating system and this portion of disk
space is not included when displaying hard disk capacity.
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.

When your computer is turned on or the battery is
charging, the base, the palm rest, and some other
parts may become hot. Avoid keeping your hands,
your lap, or any other part of your body in contact
with a hot section of the computer for any
extended length of time. When you use the
keyboard, avoid keeping your palms on the palm
rest for a prolonged period of time.
Your computer generates some heat during
normal operation. The amount of heat depends on
the amount of system activity and the battery
charge level. Extended contact with your body,
even through clothing, could cause discomfort or
even a skin burn. Periodically take breaks from
using the keyboard by lifting your hands from the
palm rest; and be careful not to use the keyboard
for any extended length of time.

When the AC adapter of your computer is
connected to an electrical outlet, it generates heat.
Do not place the adapter in contact with any part
of your body while using it. Never use the AC
adapter to warm your body. Extended contact
with your body, even through clothing, may cause
a skin burn.
Route the cables of an AC adapter, a mouse, a
keyboard, a printer, or any other electronic device,
or communication lines, so that they cannot be
walked on, tripped over, pinched by your
computer or other objects, or in any way subjected
to treatment that could disturb the operation of
your computer. Applying strong force to the
cables may damage or break them.

Before moving your computer, do one of the
following: turn it off or press Fn + F1 to put it in
sleep mode.
Before moving the computer, make sure that the
power on indicator is off. This will help to prevent
damage to the hard disk drive, and possible loss of
data.
Do not drop, bump, scratch, twist, hit, vibrate, or
push your computer, display, or external devices.
