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:

https://pcsupport.lenovo.com/supportphonelist

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.

• 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 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.

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 mm 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.

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.

Checking the battery status

Move your pointer to the battery-status icon in the Windows notification area to check the battery status. The battery-status icon displays the percentage of battery power remaining and how long you can use your computer before you must charge the battery.

The rate at which you use battery power determines how long you can use the battery of your computer between charges. Because every computer user has individual habits and needs, it is difficult to predict how long a battery charge lasts. There are two main factors:

• How much energy is stored in the battery when you begin to work

• The way you use your computer, for example:

– How often you access the storage drive – How bright you make the computer display – How often you use the wireless feature

Charging the battery

When you find that the remaining battery power is low, charge your battery.

If an ac outlet is convenient, connect the computer to ac power. The battery is fully charged in about four to eight hours. If the 65-watt power adapter shipped with your computer supports the rapid charge function, the battery is 80% charged in about an hour when the computer is turned off. The actual charging time depends on the battery size, the physical environment, and whether you are using the computer. You can check the battery charging status at any time through the battery-status icon in the Windows notification area.

Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining power is greater than 95%.

When to charge the battery

• Battery charging is affected by its temperature. The recommended temperature range for charging the battery is between 10°C (50°F) and 35°C (95°F).

Chapter 5. Security

This chapter provides information about how to protect your computer from unauthorized use.

Using passwords

This topic provides information about how to use the power-on password, supervisor password, and hard disk password.

Passwords introduction

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.

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

Supervisor password

The supervisor password protects the system information stored in the ThinkPad Setup program. 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 change most of the system configuration options in 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:

is displayed, type a power-on password or a supervisor password.

• 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 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

press F1. When the icon changes to , press F1 again.

Tips on using the hard disk passwords:

• You can set the minimum length of a hard disk password.

• If you set a hard disk password of over seven characters, the storage drive can be used only with a computer that can recognize a hard disk password of over seven characters. If you then install the storage drive in a computer that cannot recognize a hard disk password that contains more than seven characters, you cannot access the drive.

• Record your password and store it in a safe place. If you forget the user hard disk password, or both user and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the storage drive. You must take your computer to a Lenovo reseller 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.

Notes: The eDrive storage drives or Trusted Computing Group (TCG) Opal-compliant storage drives provide self-encryption capabilities to secure your data.

• If a TCG Opal-compliant storage drive and a TCG Opal management software program are installed, and the TCG Opal management software program is activated, the hard disk password is not available.

• If an eDrive storage drive is installed in your computer, and your computer is preinstalled with the Windows 10 operating system, the hard disk password is not available.

If you forget your power-on password, you must take your computer to a Lenovo-authorized servicer or a marketing representative to have the password canceled. 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 correctly:

• 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.

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.

T480s User Guide

For more information about how to use the firewall program, see the help system that comes with the program.

Installing device drivers

Device drivers are programs that contain instructions for the operating system about how to operate or “drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver. If you add a component, the operating system must be instructed on how to operate that piece of hardware. After you install the driver, the operating system can recognize the hardware component and understand how to use it.

Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption and might not perform properly if corruption occurs.

It is not always necessary to download the latest drivers. However, you should download the latest driver for a component when you notice poor performance from that component or when you added a component. This action might eliminate the driver as the potential cause of a problem.

Getting the latest drivers from the Web site

You can download and install updated device drivers from the Lenovo Support Web site by doing the following:

Using system management

This topic is primarily intended for the network administrators.

Your computer is designed for manageability, so that you can redirect more resources to better meet your business objectives.

Chapter 6. Advanced configuration 73

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.

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 networkmanagement program.

To enable or disable the Wake on LAN feature, do the following:

• Message: Error: The non-volatile system UEFI variable storage is nearly full.

Note: This error indicates that the operating system or programs cannot create, modify, or delete data in the non-volatile system UEFI variable storage due to insufficient storage space after POST.

Chapter 7. Troubleshooting computer problems 79

The non-volatile system UEFI variable storage is used by the UEFI BIOS and by the operating system or programs. This error occurs when the operating system or programs store large amounts of data in the variable storage. All data needed for POST, such as BIOS setup settings, chipset, or platform configuration data, are stored in a separate UEFI variable storage.

Solution: Press F1 after the error message is displayed to enter ThinkPad Setup. A dialog asks the user for confirmation to clean up the storage. If the user selects “Yes”, all data that were created by the operating system or programs will be deleted except global variables defined by the Unified Extensible Firmware Interface Specification. If the user selects “No”, all data will be kept, but the operating system or programs will not be able to create, modify, or delete data in the storage.

If this error happens at a service center, Lenovo authorized service personnel will clean up the non-volatile system UEFI variable storage using the preceding solution.

Ethernet problems

• Problem: My computer cannot connect to the network. Solution:

Ensure that:

– The cable is installed correctly.

The network cable must be securely connected both to the Ethernet connector of your computer and to the RJ45 connector of the hub. The maximum allowable distance from the computer to hub is 100 m (328 ft). If the cable is connected and the distance is within the acceptable limits but the problem persists, try a different cable.

– You are using the correct device driver. To install the correct driver, do the following:

Chapter 7. Troubleshooting computer problems 81

1. Go to Control Panel, and ensure that you view Control Panel by Category.

2. Click Hardware and Sound ➙ Device Manager. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Double-click Network adapters to view all network adapters. If an exclamation mark ! is displayed next to the adapter name, you might not be using the correct driver or the driver might have been disabled.

4. Right-click the highlighted adapter, click Update driver, and then follow the instructions on the screen to update the driver.

– The switch port and the adapter have the same duplex setting.

If you configured the adapter for full duplex, ensure that the switch port also is configured for full duplex. Setting a wrong duplex mode can degrade performance, cause data loss, or result in lost connections.

– You have installed all networking software that is necessary for your network environment.

Check with your LAN administrator for the necessary networking software.

• Problem: The adapter stops working for no apparent reason. Solution: The network driver files might be corrupt or missing.

• Problem: My computer is a Gigabit Ethernet model and I use a speed of 1000 Mbps, the connection fails or errors occur.

Solution:

– Use Category 5 wiring and ensure that the network cable is securely connected. – Connect to a 1000 BASE-T hub/switch (not 1000 BASE-X).

• Problem: The Wake on LAN feature is not working. Solution: Ensure that Wake on LAN is enabled in ThinkPad Setup. If it is, check with your LAN

administrator for the necessary settings.

• Problem: My computer is a Gigabit Ethernet model, but it cannot connect to the network at 1000 Mbps. Instead, it connects at 100 Mbps.

Solution:

– Try another Ethernet cable. – Ensure that the link partner is set to auto-negotiate. – Ensure that the switch is 802.3ab-compliant (gigabit over copper).

Wireless-LAN problem

Problem: I cannot connect to the network using the built-in wireless network card.

Solution: Ensure that:

• The Airplane mode is off.

• Your wireless-LAN driver is the latest version.
