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.

Checking battery status
You can determine the percentage of battery power remaining by using
Windows Power Options.
Note: As each computer user has different habits and needs, it is difficult to predict
how long a battery charge will last. There are two main factors:
• The amount of energy stored in the battery when you commence work.
• The way you use your computer: for example, how often you access the
hard disk drive and how bright you make the computer display.
Charging the battery
When you find that the battery power is low, you need to charge the
battery or replace it with a fully charged one.
The battery is charged when the AC adapter is connected to the computer
and the battery is installed.
Charging time will depend on the usage environment.
You need to charge the battery in any of the following situations:
• When you purchase a new battery
• If the battery status indicator turns orange.
• If the battery has not been used for a long time
11
Chapter 2. Learning the basics
Notes:
• You are advised to insert the battery pack when using your computer to prevent
small particles from entering the inside of your computer.
• To increase the life of the battery pack, the computer does not start recharging
the battery immediately after it drops from fully charged.
• Charge the battery at a temperature between 50 °F and 80 °F (10 °C-30 °C).
• Full charge or discharge is not required.
Removing the battery pack
If you are not going to use the computer for an extended period of time, or
if you need to send your computer to Lenovo for service, etc. remove the
battery pack from the computer.
Before removing the battery pack, make sure the computer has been shut
down.

Chapter 2. Learning the basics
Handling the battery
If the rechargeable battery pack is replaced with an incorrect type, there may
be danger of an explosion. The battery pack contains a small amount of
harmful substances. To avoid possible injury and detriment to the
environment, pay attention to the following points.
Notes:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose the battery pack to water or rain.
• Do not attempt to disassemble the battery pack.
• Do not short-circuit the battery pack.
• Keep the battery pack away from children.
