Read this first This information can help you safely use your notebook 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 Limited Warranty. For more information, see "Warranty Information" in the Safety, Warranty, and Setup Guide that comes with your computer. 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 that provides power to the system clock even when the computer is unplugged, so the battery safety information applies to all computer products. Important information about using your computer Ensure that you follow the important tips given here to get the most use and enjoyment out of your computer. Failure to do so might lead to discomfort or injury, or cause the computer to fail. Protect yourself from the heat that your computer generates. When your computer is turned on or the battery is charging, the base, the palm rest, and some other parts may become hot.

Turn it off. Put it in sleep mode. Put it in hibernation mode. This helps to prevent damage to the computer, and possible loss of data. Handle your computer gently. Carry your computer carefully. Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, display, or external devices. Use a quality carrying case that provides adequate cushioning and protection. Do not pack your computer in a tightly packed suitcase or bag. Before putting your computer in a carrying case, make sure that it is off, in sleep mode, or in hibernation mode. Do not put a computer in a carrying case while it is turned on. vi Yoga 370 User Guide 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. These conditions might merely mean that an internal electronic component has failed in a safe and controlled manner. Or, they might indicate a potential safety issue. However, do not take risks or attempt to diagnose the situation yourself. Contact the Customer Support Center for further guidance. For a list of Service and Support phone numbers, see the following Web site:
http://www.lenovo.com/support/phone Frequently inspect your computer and its components for damage or 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 conditions, 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. Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are cracked, broken, or damaged. Signs of overheating, smoke, sparks, or fire. Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign substances on the battery. A cracking, hissing, or popping sound, or strong odor that comes from the product. Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord, or power adapter. The computer product, power cord, or power adapter has been exposed to water. The product has been dropped or damaged in any way. The product does not operate normally when you follow the operating instructions. Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions, or until you get a suitable replacement. 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 make Copyright Lenovo 2017 vii 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. 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. Power cords and power adapters DANGER 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 H03VV-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 cords 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 pins 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. viii Yoga 370 User Guide To prevent possible overheating, do not cover the power adapter with clothing or other objects when the power adapter is plugged into an electrical outlet.

Security This chapter provides information about how to protect your computer from unauthorized use. Using passwords You can help prevent your computer from unauthorized use by using passwords. After you set a password, a prompt is displayed on the screen each time you turn on the computer. Enter your password at the prompt. You cannot use the computer unless you type the correct password. If you have set a power-on password, a supervisor password, or a hard disk password, it unlocks automatically when the computer resumes from sleep mode. Note: If a Windows password has been set, you are prompted to enter it when the computer resumes from sleep mode. Passwords introduction Power-on password You can set a power-on password to help protect your computer against unauthorized access. If you set a power-on password, the password prompt is displayed on the screen whenever you turn on the computer. You must enter the correct password to start using the computer. When this icon is displayed, type a power-on password or a supervisor password. Supervisor password The supervisor password protects the system information stored in the ThinkPad Setup program. If you have set a supervisor password, no one can change the configuration of the computer without the password. It provides the following security features:
If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad Setup program. Unauthorized users cannot access the ThinkPad Setup program without the password. The system administrator can use the supervisor password to access a computer even if the user of that computer has set a power-on password. The supervisor password overrides the power-on password. The system administrator can set the same supervisor password on many ThinkPad notebook computers to make administration easier. Hard disk passwords Setting a hard disk password prevents unauthorized access to the data on the hard disk drive. When a hard disk password is set, you are prompted to type a valid password each time you try to access the hard disk drive. The following two types of hard disk passwords can help protect the information stored on the storage drive:
User hard disk password If a user hard disk password has been set, but no master hard disk password has been, the user must enter the user hard disk password to access files and applications on the storage drive. Master hard disk password Copyright Lenovo 2017 51 The master hard disk password also requires a user hard disk password. The master hard disk password is set and used by a system administrator. It enables the administrator to access any storage drive in a system like a master key. The administrator sets the master password; then assign a user password for each computer in the network. The user can then change the user password as desired, but the administrator still can get access by using the master password. When a master hard disk password is set, only the administrator can remove the user hard disk password. When this icon is displayed, type a user hard disk password. To type a master hard disk password, press F1. When the icon changes to
, type the master hard disk password. To return to the icon
, press F1 again. Tips on using the hard disk passwords:

If you forget your hard disk password, Lenovo cannot reset your password or recover data from the storage drive. You must take your computer to a Lenovo-authorized servicer or a marketing representative to have the storage drive replaced. Proof of purchase is required, and a fee will be charged for parts and service. Maintaining the fingerprint reader The following actions could damage the fingerprint reader or cause it not to work properly:
Scratching the surface of the reader with a hard, pointed object Scraping the surface of the reader with your fingernail or anything hard Using or touching the reader with a dirty finger If you notice any of the following conditions, gently clean the surface of the reader with a dry, soft, lint-free cloth:
The surface of the reader is dirty or stained. The surface of the reader is wet. The reader often fails to enroll or authenticate your fingerprint. Chapter 5. Security 55 If your finger has any of the following conditions, you might not be able to register or authenticate it:
Your finger is wrinkled. Your finger is rough, dry, or injured. Your finger is stained with dirt, mud, or oil. The surface of your finger is different from the one when you enrolled your fingerprint. Your finger is wet. Your finger that you are currently using has not been enrolled before. To improve the situation, try the following:
Clean or wipe your hands to remove any excess dirt or moisture from the fingers. Enroll and use a different finger for authentication. Deleting data from your storage drive Some of the data stored on the storage drive might be sensitive. Handing your computer over to someone else without deleting the installed software, such as operating systems and programs, might even violate the license agreements. Be sure to delete data stored on the storage drive before you dispose of, sell, or hand over your computer. You can use the following methods to delete data from the storage drive:
Move the data to the Recycle Bin, and then empty the Recycle Bin. Format your storage drive, using the software to initialize it. Use the recovery program provided by Lenovo to bring the storage drive back to the factory default settings. These operations, however, only change the file location of the data; they do not delete the data itself. The data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of special software for data recovery. There is a risk that people of bad faith might read and misuse the critical data on storage drives for unexpected purposes. To prevent leakage of data, it is important that you delete all the data from the hard disk drive when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the hard disk drive with a hammer, or magnetically by means of strong magnetic power, thus making the data unreadable. But it is recommended that you use the software (payware) or service (pay service) developed for that purpose. The process might take several hours. For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive, Lenovo provides the Secure Data Disposal tool. Go to http://www.lenovo.com/support to download the tool. Some computers might support a Disk Encryption hard disk drive or Encryption solid-state drive and have such a drive installed. You can logically dispose of all the data on the drive in a short time by erasing the cryptographic key. The data encrypted with the old key is not physically erased but remains on the drive;
however, it cannot be decrypted without the old key. This feature is also available with the Drive Erase Utility for Resetting the Cryptographic Key and Erasing the Solid State Drive tool. Using firewalls If your system is preinstalled with a firewall program, it protects against computer Internet security threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy. 56 Yoga 370 User Guide For more information about how to use the firewall program, see the help system that comes with the program. Protecting data against viruses Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription.

Your computer is designed for manageability, so that you can redirect more resources to better meet your business objectives. This manageability, known as total cost of ownership (TCO), enables you to remotely operate client computers in the same way as you operate your own computer, such as turning on a client computer, formatting a storage drive, and installing a program. Once the computer is configured and operational, you can manage it by using the software and the manageability features that are already integrated into the client computer and the network. Desktop Management Interface The UEFI BIOS of your computer supports an interface called System Management BIOS (SMBIOS) Reference Specification, version 2.8 or later. SMBIOS provides information about the hardware components of your computer. It is the responsibility of the UEFI BIOS to provide information about itself and the devices on the system board. This specification documents the standards for getting access to this BIOS information. Preboot eXecution Environment The Preboot eXecution Environment (PXE) technology makes the computer more manageable by enabling the computer to start from a server. Your computer supports the personal computer functions that PXE requires. For example, with the appropriate LAN card, your computer can be started from the PXE server. Note: The Remote Initial Program Load (RIPL or RPL) function cannot be used with your computer. Wake on LAN The network administrator can turn on a computer from a management console by using the Wake on LAN feature. When the Wake on LAN feature is enabled, many operations, such as data transfer, software updates, and flash updates of the UEFI BIOS, can be done remotely without remote attendance. The updating process can perform after normal working hours and on weekends, so that the users are not interrupted during work, and the LAN traffic is kept to a minimum. It saves time and increases productivity. If the computer is turned on through Wake on LAN, the computer starts follow the Network Boot sequence. Asset ID EEPROM The Asset ID EEPROM contains information about the computer configuration and the serial numbers of the key components. It also includes a number of blank fields where you can record information about the end users in your network. 72 Yoga 370 User Guide To enable a network administrator to remotely control your computer, set the following system-management features in the ThinkPad Setup program:
Wake on LAN Network Boot sequence Note: If a supervisor password has been set, you are required to enter the supervisor password when you start the ThinkPad Setup program. Enabling or disabling the Wake on LAN feature When the Wake on LAN feature is enabled and the computer is connected to a LAN, the network administrator can start the computer remotely from a management console, using a remote network-management program. To enable or disable the Wake on LAN feature, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program. 2. Select Config Network. The Network submenu is displayed. 3. Select a corresponding option for the Wake on LAN feature. 4. Press F10 to save the settings and exit. Defining a Network Boot sequence When the computer wakes on LAN, the computer boots from the device as specified on the Network Boot menu, and then follow the boot order list on the Boot menu. To define a Network Boot sequence, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program. 2. Select Startup Network Boot. The boot device list is displayed. 3. Select a boot device to make it as the top boot priority. 4. Press F10 to save the settings and exit. You can press F9 to restore to the factory default settings. Chapter 6.

General tips for preventing problems This topic provides the following tips to help you prevent computing problems:
Empty your recycle bin on a regular basis. Use disk defragment tool regularly on your storage drive to improve data seek and read times. To free up disk space, uninstall unused programs. You also might want to look for program duplication or overlapping versions. Clean out your Inbox, Sent, and Trash folders from your e-mail client program. Back up your data at least once a week. If critical data is present, it is a good idea to back up the data daily. Lenovo has many backup options available for your computer. Schedule system restore operations to take a system snapshot periodically. For information about system restore, see Recovery information on page 91. Go to http://www.lenovo.com/support to download and install updates for the device drivers and UEFI BIOS when needed. Keep up to date for device drivers on other non-Lenovo hardware. Before updating device drivers, read the device driver information release notes for compatibility or known issues. Keep a log book. Entries might include major hardware or software changes, driver updates, minor issues you have experienced, and how you resolved the minor issues. If you ever need to run a recovery on your computer to return the preinstalled contents onto the machine, the following tips might help along the way:
1. Remove all external devices such as the printer and keyboard. 2. Ensure that your battery is charged and your computer has the ac power connected. 3. Access ThinkPad Setup and load the default settings. 4. Restart the computer and start the recovery operation. 5. If your computer uses discs as the recovery media, do not remove the disc from the drive until prompted to do so.
