Refer to the information in this section and the safety information in the Safety, Warranty, and Setup Guide that you received with this product. Reading and understanding this safety information reduces the risk of personal injury and damage to your product. If you no longer have a copy of the Safety, Warranty, and Setup Guide, you can obtain a Portable Document Format (PDF) version from the Lenovo® Support Web site at http://www.lenovo.com/UserManuals. The Lenovo Support Web site also provides the Safety, Warranty, and Setup Guide and this User Guide in additional languages. 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 a power cord, always ensure that the power is turned off and that the product is unplugged from any power source. For more information on CRUs, refer to Chapter 5 “Installing or replacing hardware” on page 39. If you have any questions or concerns, contact the Customer Support Center. 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. CAUTION: Before you open the computer cover, turn off the computer and wait several minutes until the computer is cool. Static electricity prevention Static electricity, although harmless to you, can seriously damage computer components and options. Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option © Copyright Lenovo 2013, 2014 v or CRU, do not open the static-protective package containing the part until the instructions direct you to install it. When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage: • Limit your movement. Movement can cause static electricity to build up around you. • Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the edges. Never touch exposed circuitry. • Prevent others from touching components. • When you install a static-sensitive option or CRU, touch the static-protective package containing the part to a metal expansion-slot cover or other 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 static-sensitive part from the static-protective packaging and install the part without setting it down. When this is not possible, place the static-protective packaging on a smooth, level surface and place the part on it. • Do not place the part on the computer cover or other metal surface. Power cords and power adapters Use only the power cords and power adapters supplied by the product manufacturer. The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For other countries, the suitable types shall be used accordingly. Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter, which can eventually result in overheating. Ensure that all power cord connectors are securely and completely plugged into receptacles. Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such as deformed plastic) at the ac input or anywhere on the power adapter. Do not use any power cords where the electrical contacts on either end show signs of corrosion or overheating or where the power cord appears to have been damaged in any way. Extension cords and related devices Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use are rated to handle the electrical requirements of the product. Never overload these devices. If power strips are used, the load should not exceed the power strip input rating. Consult an electrician for more information if you have questions about power loads, power requirements, and input ratings. vi ThinkCentre E93z User Guide Plugs and outlets If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged or corroded, do not use the outlet until it is replaced by a qualified electrician. Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement. Do not share an electrical outlet with other home or commercial appliances that draw large amounts of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices. Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information if you have questions about power loads and branch circuit ratings. Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the equipment. Do not fully extend power cords in a way that will stress the cords. Be sure that the power outlet provides the correct voltage and current for the product you are installing. Carefully connect and disconnect the equipment from the electrical outlet. External devices Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) and 1394 cables while the computer power is on; otherwise, you might damage your computer. To avoid possible damage to attached devices, wait at least five seconds after the computer is shut down to disconnect external devices. Heat and product ventilation Computers, power adapters, and many accessories can generate heat when turned on and when batteries are charging. Always follow these basic precautions: • Do not leave your computer, power adapter, or accessories in contact with your lap or any part of your body for an extended period when the products are functioning or when the battery is charging. Your computer, power adapter, and many accessories produce some heat during normal operation. Extended contact with the body could cause discomfort or, potentially, a skin burn. • Do not charge the battery or operate your computer, power adapter, or accessories near flammable materials or in explosive environments. • Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable operation. These features might inadvertently become blocked by placing the product on a bed, sofa, carpet, or other flexible surface. Never block, cover, or disable these features. Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting your computer, turn off the power and unplug the computer's power cord from the electrical outlet; then remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, then examine and remove dust from the inside of the computer including heat sink inlet fins, power supply vents, and fans. Always turn off and unplug the computer before opening the cover. If possible, avoid operating your computer within two feet of high-traffic areas. If you must operate your computer in or near a high-traffic area, inspect and, if necessary, clean your computer more frequently. © Copyright Lenovo 2013, 2014 vii For your safety and to maintain optimum computer performance, always follow these basic precautions with your desktop computer: • Keep the cover closed whenever the computer is plugged in. • Regularly inspect the outside of the computer for dust accumulation. • Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for computers in dusty or high-traffic areas. • Do not restrict or block any ventilation openings. • Do not store or operate your computer inside furniture, as this might increase the risk of overheating. • Airflow temperatures into the computer should not exceed 35°C (95°F). • Do not install air filtration devices. They may interfere with proper cooling. Operating environment The optimal environment in which to use your computer is 10°C-35°C (50°F-95°F) with humidity ranging between 35% and 80%. If your computer is stored or transported in temperatures less than 10°C (50°F), allow the cold computer to rise slowly to an optimal operating temperature of 10°C-35°C (50°F-95°F) before use. This process could take two hours in extreme conditions. Failure to allow your computer to rise to an optimal operating temperature before use could result in irreparable damage to your computer. If possible, place your computer in a well-ventilated and dry area without direct exposure to sunshine. Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and microwave oven away from your computer because the strong magnetic fields generated by these appliances can damage the monitor and data on the hard disk drive. Do not place any beverages on top of or beside the computer or other attached devices. If liquid is spilled on or in the computer or an attached device, a short circuit or other damage might occur. Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage. Laser compliance statement CAUTION: When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or transmitters) are installed, note the following: • Do not remove the covers. Removing the covers of the laser product could result in exposure to hazardous laser radiation. There are no serviceable parts inside the device. • Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure. DANGER Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following: Laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam. viii ThinkCentre E93z User Guide Power supply statement Never remove the cover on a power supply or any part that has the following label attached. Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician. Cleaning and maintenance Keep your computer and workspace clean. Shut down the computer and then disconnect the power cord before cleaning the computer. Do not spray any liquid detergent directly on the computer or use any detergent containing flammable material to clean the computer. Spray the detergent on a soft cloth and then wipe the computer surfaces. Tip-over hazard prevention notice • Place the computer on a sturdy and low base, or anchor the furniture and position the computer as far back on the furniture as possible. • Keep remote controls, toys, and other items that might attract children off the computer. • Keep the computer, cables, and cords out of the reach of children. • Supervise children in rooms where these safety tips have not been followed. © Copyright Lenovo 2013, 2014 ix x ThinkCentre E93z User Guide Chapter 1.

You and your computer This chapter provides information about accessibility, comfort, and relocating your computer to other countries or regions. Accessibility and comfort Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort while using your computer. The following topics provide information about arranging your work area, setting up your computer equipment, and establishing healthy work habits. Lenovo is committed to providing people with disabilities greater access to information and technology. As a result, the following information provides ways to help users that have hearing, vision, and mobility limitations get the most out of their computer experience. Assistive technologies enable users to access information in the most appropriate way. Some of these technologies are already provided in your operating system, others can be purchased through vendors, or accessed through the World Wide Web: http://www.lenovo.com/healthycomputing Arranging your workspace To get the most from your computer, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets can also affect the way you arrange your workspace. Comfort Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best. Sitting in the same position for a long time can cause fatigue. The backrest and seat of your chair should adjust independently and provide good support. The seat should have a curved front to relieve pressure on the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the floor or on a footrest. When using the keyboard, keep your forearms parallel to the floor and your wrists in a comfortable position. Use a light touch on the keyboard and your hands and fingers relaxed. Change the angle of the keyboard for maximum comfort by adjusting the position of the keyboard feet. © Copyright Lenovo 2013, 2014 27 Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 inches), and position it so you can view it without having to twist your body. Also, position other equipment you use regularly, such as the telephone or a mouse, within easy reach. Glare and lighting Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor as the room lighting changes throughout the day. Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare. Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth as directed in your monitor documentation. Air circulation Your computer and monitor produce heat. The computer has a fan that pulls in fresh air and forces out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents; usually, 51 mm (2 inches) of air space is sufficient. Also, ensure the vented air is not blowing on people. Electrical outlets and cable lengths The location of electrical outlets, the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your computer. When arranging your workspace: • Avoid the use of extension cords. When possible, plug the computer power cord directly into an electrical outlet. • Keep power cords and cables neatly routed away from walkways and other areas where they might get kicked accidentally. For more information about power cords, see “Power cords and power adapters” on page vi. 28 ThinkCentre E93z User Guide Accessibility information Lenovo is committed to providing people with disabilities greater access to information and technology.

Handling static-sensitive devices Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts. When you handle parts and other computer components, take these precautions to avoid static-electricity damage: • Limit your movement. Movement can cause static electricity to build up around you. • Always handle parts and other computer components carefully. Handle PCI cards, 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 static-protective package containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the package and your body. • When possible, remove the new part from the static-protective packaging, and install it directly in the computer without setting the part down. When this is not possible, place the static-protective 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.

Cleaning and maintenance With appropriate care and maintenance your computer will serve you reliably. The following topics offer information to help you keep your computer in top working order. • “Basics” on page 66 • “Cleaning your computer” on page 67 • – “Computer” on page 67 – “Keyboard” on page 67 – “Optical mouse” on page 67 – “Display screen” on page 67 “Good maintenance practices” on page 68 Basics Here are some basic points about keeping your computer functioning properly: • Keep your computer in a clean, dry environment. Ensure it rests on a flat, steady surface. • Do not place items on top of the monitor or cover any of the vents in the monitor or computer. These vents provide airflow to keep your computer from overheating. • Keep food and drinks away from all parts of your computer. Food particles and spills might make the keyboard and mouse stick and unusable. • Do not get the power switches or other controls wet. Moisture can damage these parts and cause an electrical hazard. • Always disconnect a power cord by grasping the plug, but not the cord. 66 ThinkCentre E93z User Guide Cleaning your computer It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free operation. CAUTION: Be sure to turn off the computer and monitor power switches before cleaning the computer and monitor screen. Computer Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer. Keyboard To clean your computer keyboard, do the following: 1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth. 2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time, the cloth may hook onto an adjacent key and possibly damage it. Ensure that no liquid drips onto or between the keys. 3. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush or cool air from a hair dryer. Note: Avoid spraying cleaner directly onto the display or the keyboard. Optical mouse This section provides instructions on how to clean an optical mouse. An optical mouse uses a light-emitting diode (LED) and an optical sensor to navigate the pointer. If the pointer on the screen does not move smoothly with the optical mouse, you might need to clean the mouse. To clean an optical mouse, do the following: 1. Turn off your computer. 2. Disconnect the mouse cable from the computer. 3. Turn the mouse upside down to check the lens. a. If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab. b. If there is debris in the lens, gently blow the debris away from the area. 4. Check the surface on which you are using the mouse. If you have a very intricate picture or pattern beneath the mouse, it may be difficult for the digital signal processor (DSP) to determine changes in the mouse position. 5. Reconnect the mouse cable to the computer. 6. Turn your computer back on. Display screen Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically. See “Cleaning a flat-panel monitor surface” on page 67 or “Cleaning a glass-screen surface” on page 68. Cleaning a flat-panel monitor surface If you have a flat-panel computer display that has a flexible film surface, do the following to clean the special surface. Wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and other loose particles. Then moisten a cloth with LCD cleaner and wipe the screen surface. Chapter 9. Preventing problems 67 Many computer supply stores carry the special cleaning fluids for displays. Use cleaning fluids developed for LCD displays only. First apply the fluid to a lint-free, soft cloth, then clean the LCD display. Some computer supply stores carry pre-moistened towelettes for LCD maintenance. Cleaning a glass-screen surface To clean a glass-screen surface, wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and other loose particles. Then use a soft cloth moistened with a nonabrasive liquid glass cleaner. Good maintenance practices By performing a few good maintenance practices, you can maintain good computer performance, protect your data, and be prepared in case of a computer failure. • Empty your recycle bin on a regular basis. • Run the Windows Disk Defragmenter program occasionally to prevent performance problems caused by an excessive number of fragmented files. • Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis. • Make backup copies of critical data on removable media memory at regular intervals and store the removable media in a safe location. The frequency of making backup copies depends on how critical the data is to you or your business. Lenovo makes a number of removable-media storage devices available as options, such as CD-RW drives and recordable DVD drives. • Back up your entire hard disk drive on a regular basis. • Keep your computer software up-to-date. See “Keeping your computer current ” on page 65 for more information. • Keep a log book. Entries might include major software or hardware changes, device-driver updates, intermittent problems and what you did to resolve them, and any minor issues you might have experienced. A log book can help you or a Lenovo technician determine if a problem is related to change in hardware, change in software, or some other action that might have taken place. • Create Product Recovery discs. See “Creating and using recovery media” on page 49 for more information about using Product Recovery discs to restore the hard disk drive to the factory default settings. • Create rescue media. See “Creating and using a rescue medium” on page 52 for more information about using a Rescue medium such as a CD or DVD to recover from failures that prevent you from gaining access to the Windows environment or the Rescue and Recovery workspace on your hard disk drive. Moving your computer Take the following precautions before moving your computer. 1. Back up all files and data from the hard disk drive. There are a variety of backup programs available commercially. Your operating system also might have a backup program that you can use. Lenovo provides the Rescue and Recovery program to help you back up and restore data. See “Performing backup and recovery operations” on page 50 for more information. 2. Remove all media (diskettes, compact discs, tapes, and so on) from the drives. 3. Turn off the computer and all attached devices. Your hard disk drive automatically parks the read/write head in a nondata area. This prevents damage to the hard disk drive. 4. Unplug the power cords from electrical outlets. 5. Disconnect communication cables, such as modem or network cables, from the outlets first, and then disconnect the other ends from the computer. 6. Note where any remaining cables are attached to the computer; then, remove them. 7. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are using different cartons, cushion the units to avoid damage. 68 ThinkCentre E93z User Guide Chapter 10.
