Important safety information

Note: Read the important safety information first.

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 and Warranty 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

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. The temperature they reach

depends on the amount of system activity and the level of charge in the

battery.

Extended contact with your body, even through clothing, could cause

discomfort or even a skin burn.

• Avoid keeping your hands, your lap, or any other part of your body in

contact with a hot section of the computer for any extended time.

• Periodically take hands from using the keyboard by lifting your hands from

the palm rest.

Protect yourself from the heat generated by the ac power adapter.

When the ac power adapter is connected to an electrical outlet and your

computer, it generates heat.

Extended contact with your body, even through clothing, may cause a skin

burn.

• Do not place the ac power adapter in contact with any part of your body

while it is in use.

• Never use it to warm your body.

• Do not wrap the cords around the ac power adapter while in use.

Prevent your computer from getting wet.

To avoid spills and the danger of electrical shock, keep liquids away from your

computer.

Protect the cables from being damaged.

Applying strong force to cables may damage or break them.

Route communication lines, or the cables of an ac power adapter, a mouse, a

keyboard, a printer, or any other electronic device, so that they cannot be

walked on, tripped over, pinched by your computer or other objects, or in any

way subject to treatment that could interfere with the operation of your

computer.

Protect your computer and data when moving it.

Before moving a computer equipped with a hard disk drive, do one of the

following:

• 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.

iv T580 and P52s User Guide

Handle your computer gently.

Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on

your computer, display, or external devices.

Carry your computer carefully.

• 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.

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:

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.

• 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

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.

vi T580 and P52s User Guide

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.

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.

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.

Plugs and outlets

DANGER

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.

Power supply statement

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 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. 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:

• User hard disk password

If a user hard disk password has been set, but no master hard disk password has been set, 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 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:

• 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.

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.

Setting, changing, or removing a password

Before you start, print these instructions.

To set, change, or remove a password, do the following:

1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.

2. Select Security ➙ Password by using the directional keys.

3. Depending on the password type, select Power-on Password, Supervisor Password, or Hard disk x

Password.

4. Follow the instructions on the screen to set, change, or remove a password.

You should record all your passwords and store them in a safe place. If you forget any of your passwords,

any potential repair actions required are not covered under warranty.

What to do if you forget your power-on password

If you forget your power-on password, do the following to remove the power-on password:

• If you have set a supervisor password and remember it:

1. Restart the computer. When the logo screen is displayed, immediately press F1.

2. Type the supervisor password to enter the UEFI BIOS menu.

reset your passwords or recover data from the storage drive. You can contact a Lenovo authorized service

provider to have the storage drive replaced. A fee will be charged for parts and service. If the storage drive is

a CRU (Customer Replaceable Unit), you can also contact Lenovo to purchase a new storage drive to

replace the old one by yourself. To check whether the storage drive is a CRU and the relevant replacement

procedure, see Chapter 9 “Replacing devices” on page 99.

What to do if you forget your supervisor password

If you forget your supervisor password, there is no service procedure to remove the password. You have to

contact a Lenovo authorized service provider to have the system board replaced. A fee will be charged for

parts and service.

Hard disk security

To protect the computer from unauthorized security attacks, refer to the following tips to enhance security:

• Set a power-on password as well as a hard disk password. For security, a longer password is

recommended.

• The hard disk drive built into your computer can be protected by UEFI BIOS. To provide reliable security,

use the security chip and a security program with the Trusted Platform Module (TPM) management

feature. See “Setting the security chip” on page 56.

• If a Disk Encryption storage drive is installed in your computer, ensure to protect the contents of your

computer from unauthorized access by use of drive encryption software, such as Microsoft Windows

BitLocker® Drive Encryption.

• Before you dispose of, sell, or hand over your computer, delete the data stored on it. For more

information, see “Deleting data from your storage drive” on page 58.

Using Windows BitLocker Drive Encryption

To help protect your computer against unauthorized access, use the drive encryption software, such as

Windows BitLocker Drive Encryption.

Windows BitLocker Drive Encryption (referred to as BitLocker) is an integral security feature of some editions

of the Windows operating system. It can help you protect the operating system and data stored on your

computer, even if your computer is lost or stolen. BitLocker can encrypt all user and system files, including

the swap and hibernation files.

BitLocker uses the TPM to provide enhanced protection for your data and to ensure early boot component

integrity. A compatible TPM is defined as a V2.0 TPM.

To check the BitLocker status, go to Control Panel, view Control Panel by Category, and click System and

Security ➙ BitLocker Drive Encryption.

Chapter 5.Security 55

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.

58 T580 and P52s User Guide

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.

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:

1. Go to https://support.lenovo.com.

2. Select the entry for your computer and then follow the instructions on the screen to download and install

necessary software.

Getting the latest drivers using Lenovo Vantage

The system update function of Lenovo Vantage helps you keep the software on your computer up-to-date.

Update packages are stored on Lenovo servers and can be downloaded from the Lenovo Support Web site.

Update packages can contain applications, device drivers, UEFI BIOS flashes, or software updates. When

Lenovo Vantage connects to the Lenovo Support Web site, the program automatically recognizes the

following information and determines what updates are available for your computer:

• Machine type and model of your computer

• Installed operating system

• Language of the operating system

Lenovo Vantage then displays a list of update packages and categorizes each update as critical,

recommended, or optional to help you understand the importance. You have complete control of which

updates to download and install. After you select the update packages you want, Lenovo Vantage

automatically downloads and installs the updates.

Lenovo Vantage is preinstalled on your computer and is ready to run. The only prerequisite is an active

Internet connection. You can start the program manually, or you can use the schedule feature to enable the

62 T580 and P52s User Guide

program to search for updates automatically at specified intervals. You also can predefine scheduled

updates to search by the critical severity level so the list you choose from contains only those update types

that you need.

For more information about how to use Lenovo Vantage, see the help system of the program.

Using the ThinkPad Setup program

The ThinkPad Setup program enables you to select the preferred settings for your computer through

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.

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

76 T580 and P52s User Guide

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 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:

Chapter 6.Advanced configuration 77

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 7. Troubleshooting computer problems

This chapter provides information about what to do if you experience a problem with your computer.

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 a 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 Chapter 8 “Recovery information” on page 97.

• Go to https://support.lenovo.com 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.

Diagnosing problems

Many computer problems can be solved without outside assistance. If you experience a problem with your

computer, the first place to start is the troubleshooting information in your computer documentation. If you

suspect a software problem, see the documentation, including readme files and help information systems,

that come with the operating system or program. ThinkPad notebook computers come with a set of

diagnostic programs that you can use to help you identify hardware problems.

Note: If you are unable to isolate and repair the problem yourself after running Lenovo Vantage, save and

print the log files created by the program. You need the log files when you speak to a Lenovo technical

support representative.

Lenovo Vantage supports the hardware scan function. It combines diagnostic tests, system information

collection, security status, and support information, along with hints and tips for optimal system

performance. To run Lenovo Vantage, see “Accessing Lenovo programs” on page 14.

The troubleshooting information or the diagnostic programs might tell you that you need additional or

updated device drivers or other software. You can get the latest technical information and download device

drivers and updates from the Lenovo Support Web site at:

https://support.lenovo.com

For additional information, see the help system of the program.

Troubleshooting

If your computer has an error, it typically displays a message or an error code, or makes a beep when you

turn it on. When you experience a problem, see the corresponding symptom and solution in this topic to try

to solve the problem by yourself.

Important WEEE information

The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for

example, the European WEEE Directive, India E-Waste Management Rules). Appliances are labeled in

accordance with local regulations concerning waste electrical and electronic equipment (WEEE). These

regulations determine the framework for the return and recycling of used appliances as applicable within

each geography. This label is applied to various products to indicate that the product is not to be thrown

away, but rather put in the established collection systems for reclaiming these end of life products.

Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of life

EEE as unsorted municipal waste, but use the collection framework available to them for the return, recycle,

and recovery of WEEE and to minimize any potential effects of EEE on the environment and human health

due to the presence of hazardous substances. Lenovo electrical and electronic equipment (EEE) may contain

Battery recycling information for the European Union

Notice: This mark applies only to countries within the European Union (EU).

Batteries or packaging for batteries are labeled in accordance with European Directive 2006/66/EC

concerning batteries and accumulators and waste batteries and accumulators. The Directive determines the

framework for the return and recycling of used batteries and accumulators as applicable throughout the

European Union. This label is applied to various batteries to indicate that the battery is not to be thrown

away, but rather reclaimed upon end of life per this Directive.

In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate

that they are to be collected separately and recycled at end of life. The label on the battery may also include

a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for cadmium).

Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted municipal

waste, but use the collection framework available to customers for the return, recycling, and treatment of

batteries and accumulators. Customer participation is important to minimize any potential effects of batteries

and accumulators on the environment and human health due to the potential presence of hazardous

substances.

Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection

facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries

and accumulators for separate collection.

contact Lenovo for service. If you need to dispose of a lithium battery, insulate it with vinyl tape, contact your

place of purchase or a waste-disposal operator, and follow their instructions.

Disposing of battery packs from Lenovo products

Your Lenovo device might contain a lithium-ion battery pack or a nickel metal hydride battery pack. You can

find details on the battery pack in the product documentation. If you need to dispose of a battery pack,

insulate it with vinyl tape, contact Lenovo sales, service, or your place of purchase, or a waste-disposal

operator, and follow their instructions. You also can refer to the instructions provided in the user guide for
