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.

Do not distort, bend or extrude your liquid crystal

display.

Do not place heavy objects on your computer or

display.
