Troubleshooting software problems
Problem: You are unable to exit a running program normally.
Troubleshooting and problem resolution:
1. Press the Ctrl, Alt and Delete keys at the same time, then select the Task Manager
option from the Windows logon screen.
2. Select the problem program, then click the End Task button.
Problem: You need to install or uninstall a program.
Problem resolution:
During installation never abort the install process by powering the system off or
through other drastic means. This can cause system program problems or even failure
during system initialization.
During the uninstall process, never directly delete the files or folders. This is harmful
to the operating system, and might cause a system-wide malfunction. Use the following
procedure to properly uninstall programs:
1. Back up all documents and system settings related to the program before removing
it.
2. If the program has its own uninstaller, run it directly to uninstall the program.
3. If the program does not have its own uninstaller, use the search box on the taskbar
to open the Control Panel.
4. From the Control Panel, choose Programs →Programs and Features.
5. Find the program in the Programs and Features dialog box and then select
Uninstall/Change.
6. Follow the prompts displayed to uninstall the software.
Troubleshooting problems with optical
drives and hard disks
Problem: The optical drive is unable to read a CD/DVD.
Troubleshooting and problem resolution:
1. Check to see if there is an optical drive icon in the resource manager of the operating
system. If not, restart your computer. If there is still no icon, contact Lenovo Service.
Otherwise, continue with the next step of this procedure.
2. 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.
3. Check the specifications that came with your computer to confirm that this optical
drive is capable of reading this type of CD or DVD.

-9-
4. If the CD/DVD cannot be read, replace it with a known good CD/DVD such as one
that was shipped with the computer.
5. 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:
40G x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
The capacity of the hard disk shown in the system can be obtained by
subtracting the service partition:
3G x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 2.79G.
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 10 system.
Problem: The operating system fails to start up.
Troubleshooting and problem resolution:
If the computer is installed with an Optane memory:
• EnsurethattheOptanememoryisnotremoved.
• ChecktheOptanememoryusingthediagnostictoolthatispreinstalledinyour
computer, to ensure it is not damaged.

computer, you must change the boot mode to Legacy support. The legacy Windows
operating system cannot be installed if you don’t change the boot mode.
Performing daily maintenance tasks
Cleaning the computer components
Because many of the computer components consist of sophisticated integrated circuit
boards, it is very important to periodically clean the computer to prevent dust buildup.
The cleaning supplies you need to clean the components include: a vacuum cleaner, a
soft cotton cloth, pure water (preferably purified or distilled water) and cotton swabs.
ATTENTION:
Before you clean your computer, disconnect the computer from the electrical
outlet. Clean your computer with a soft cloth dampened with water. Do not use
liquid or aerosol cleaners, which may contain flammable substances.
NOTE:
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,

This information can help you safely use your desktop or notebook personal computer.
Follow and retain all information included with your computer. The information in this
document does not alter the terms of your purchase agreement or the Lenovo™ Limited
Warranty. For more information, refer to “Lenovo Limited Warranty.”
Customer safety is important. Our products are developed to be safe and effective.
However, personal computers are electronic devices. Power cords, power adapters,
and other features can create potential safety risks that can result in physical injury or
property damage, especially if misused. To reduce these risks, follow the instructions
included with your product, observe all warnings on the product and in the operating
instructions, and review the information included in this document carefully. By
carefully following the information contained in this document and provided with your
product, you can help protect yourself from hazards and create a safer computer work
environment.
NOTE:
This information includes references to power adapters and batteries. In addition
to notebook computers, some products (such as speakers and monitors) ship with
external power adapters. If you have such a product, this information applies to
your product. In addition, computer products contain a coin-sized internal battery

Conditions that require immediate
action
Products can become damaged due to misuse or neglect. Some product damage is
serious enough that the product should not be used again until it has been inspected
and, if necessary, repaired by an authorized servicer.
As with any electronic device, pay close attention to the product when it is turned on.
On very rare occasions, you might notice an odor or see a puff of smoke or sparks vent
from your product, or you might hear sounds like popping, cracking, or hissing. This
might just mean that an internal electronic component has failed in a safe and controlled
manner. However, they might indicate a potential safety issue. Do not take risks or
attempt to diagnose the situation yourself. Contact the Customer Support Center for
further guidance.
Frequently inspect your computer and its components for damage, wear, or signs
of danger. If you have any question about the condition of a component, do not use
the product. Contact the Customer Support Center or the product manufacturer for
instructions on how to inspect the product and have it repaired if necessary.
In the unlikely event that you notice any of the following, or if you have any safety
concerns with your product, stop using the product and unplug it from the power
source and telecommunication lines until you can speak to the Customer Support
Center for further guidance.

General safety guidelines
Always observe the following precautions to reduce the risk of injury and property
damage.
Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer
Support Center or your documentation. Only use a service provider who is approved to
repair your particular product.
NOTE:
Some computer parts can be upgraded or replaced by the customer. Upgrades
typically are referred to as options. Replacement parts approved for customer
installation are referred to as Customer Replaceable Units, or CRUs. Lenovo
provides documentation with instructions when it is appropriate for customers
to install options or replace CRUs. You must closely follow all instructions when
installing or replacing parts. The Off state of a power indicator does not necessarily
mean that voltage levels inside a product are zero. Before you remove the covers
from a product equipped with an ac power cord, always make sure that the power
is turned off and that the product is unplugged from any power source. If you have
any questions or concerns, contact the Customer Support Center.
After replacing a CRU, reinstall all protective covers, including the computer cover,
before connectingpower and operating the computer. This action is important to help
prevent unexpected electricalshock and help ensure the containment of an unexpected
fire that could happen under extremelyrare conditions.
Although there are no moving parts in your computer after the power cord has been
disconnected, the following warnings are required for your safety.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.

-15-
CAUTION:
Avoid contact with hot components inside the computer. During operation, some
components become hot enough to burn the skin. Before you open the computer
cover, turn off the computer, disconnect power, and wait ten minutes for the
components to cool down.
Hazardous energy statement
Disconnect all power cords from electrical outlets before removing the computer cover
or any part that has the above label attached.
CAUTION:
Bright Light, possible skin or eye damage. Disconnect power before servicing.
CAUTION:
Infrared Light, possible skin or eye damage. Disconnect power before servicing.
CAUTION:
When replacing CRUs, be cautious of sharp edges or corners that might cause
