  • Adjust the Windows volume control — select the speaker icon from the Settings Charm or click the arrow on the taskbar to show the hidden icons in Windows desktop mode, then click the speaker icon. Ensure that the volume is turned up and the sound is not muted.

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 pop-up dialogue box.
  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 installation 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.

  4. From the Control Panel, choose Programs → Programs and Features.
  5. Find the applicable program from the Programs and Features dialogue box and then select Uninstall/Change.
  6. Perform the instructions 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 determine 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.
  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: 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 keylenovo-E50-Series-Affordable-15.6-Inch-Business-Notebook-fig-9 + 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.

BIOS setup utility

What is the BIOS setup utility?
The BIOS setup utility is ROM-based software. It communicates basic computer information and provides options for setting boot devices, security, hardware mode, and other preferences.

How can I start the BIOS setup utility?
To start the BIOS setup utility:

  1. Shut down the computer.
  2. Repeatedly press and release the F1 key once turning on the computer to start the Setup Utility program.

How can I change the boot mode?
There are two boot modes: UEFI and Legacy. To change the boot mode, start the BIOS setup utility and select Startup → Boot Priority, then set boot mode to UEFI or Legacy support on the boot menu.

When do I need to change the boot mode?
The default boot mode for your computer is the UEFI mode. If you need to install a legacy Windows operating system (any operating system before Windows 8.1) on your 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, 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.

Tools required
To disassemble the computer, you need the following tools:

  • Wrist grounding strap and conductive mat for preventing electrostatic discharge
  • Flat screwdriver
  • Phillips screwdriver
  • Hex screwdriver
  • 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.
