Confirm that the CD/DVD has been properly placed in the drive. If not, reload the CD or DVD. Otherwise, continue with the next step of this procedure.
Check the specifications that came with your computer to confirm that this optical drive is capable of reading this type of CD or DVD.
If the CD/DVD cannot be read, replace it with a known good CD/DVD such as one that was shipped with the computer.
If the known good CD cannot be read, visually check the operating side of the CD/DVD for defects.

Problem:
The capacity of the hard disk, as indicated by the system, is less than the nominal capacity.

Troubleshooting and problem resolution:
For computers equipped with the OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit.

Further Technical Explanation:
The nominal capacity of the hard disk is expressed in the decimal system as 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity 1G is 1000M, while the actual capacity 1G is 1024M).

The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example:

The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
If the Service partition of 3G – 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 2.79G is subtracted, the capacity of the hard disk shown in the system can be obtained.

The capacity of the hard disk as calculated using this method may be slightly different from the actual capacity due to the rounding of totals.

Special considerations for troubleshooting Windows
Record the following information as it may be useful later when troubleshooting system problems:

The drivers for this computer model only support the Windows 8.1 system.

Windows Help and Support
If you have a problem with the operating system, see the Windows Help and Support file. To open the Windows Help and Support file, do one of the following:

Select the Settings charm, then select Help.
Press Windows key + F1.

You can read the Windows Help and Support file on your computer. You can also get online help and support by clicking on one of the two links listed under More to explore.

To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for cleaning displays, and follow the instructions included with the product.

The following are general methods for cleaning the components:

You can use a soft cloth to remove dust on the surface of the computer, the monitor, the printer, the speakers and the mouse.
You can use a vacuum cleaner to clean in otherwise inaccessible corners.
To clean the keyboard thoroughly, shut down the computer and scrub it gently with a wet cloth. Do not use the keyboard until it is dry.

Do not do any of the following:

Allow water to enter the computer.
Use a heavily dampened cloth.
Spray water directly onto the surface of the monitor or inside the computer.

LCD monitor should be cleaned daily. Use a dry cloth to brush dust from the monitor and keyboard every day. Keep all surfaces clean and free of grease stains.

Hardware Replacement Guide

Overview

This guide is intended to be used by customers who are replacing Customer Replaceable Units (CRUs) as well as trained service personnel who are replacing Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will be referred to as parts.

Note:
Trained service personnel should refer to the Hardware Maintenance Manual (HMM) for parts ordering information.

This guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts can be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo™.

The description of the TV card in this manual applies only to machines that have a TV card. It does not apply to machines that do not have a TV card.

This guide contains procedures for replacing the following parts:

Memory modules
Hard disk drive
Optical drive

Plastic flat screwdriver
Plastic tweezers

Note:
The screws for the different components vary in size. During the disassembly procedure, group the screws with their corresponding components to avoid a mismatch when replacing the components.

Handling static-sensitive devices

Static electricity is harmless to you, but it can seriously damage computer components.
When you are replacing a part, do not open the antistatic package containing the new part until the defective part has been removed from the computer and you are ready to install the new part.

Take these precautions to avoid static electricity damage when handling parts and other computer components:

Limit your movement. Movement can cause static electricity to build up around you.
Always handle parts and other computer components carefully. Handle adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
Prevent others from touching the parts and other computer components.
Before you replace a new part, touch the antistatic package containing the part to a metal expansion slot cover or another unpainted metal surface on
the computer for at least two seconds. This reduces static electricity in the package and your body.
When possible, remove the new part from its antistatic packaging and install it directly into the computer without setting the part down. When this is not possible, place the antistatic package that the part came in on a smooth, level surface and place the part on it.
Do not place the part on the computer cover or other metal surface.
