Power cords and power adapters
DANGER
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
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 mm
2, 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.

Rechargeable battery notice
DANGER
Lithium coin cell battery notice
DANGER
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to
“vent” from the battery pack or coin cell. If your battery is damaged, or if you notice any discharge
from your battery or the buildup of foreign materials on the battery leads, stop using the battery and
obtain a replacement from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For some rechargeable
batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could
increase the risk of a battery short circuit, which could shorten the life of the battery and also can
pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store
these batteries in a discharged state.
Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause an
explosion, or liquid leakage from the battery pack. A battery pack other than the one specified by
Lenovo, or a disassembled or modified battery pack is not covered by the warranty.
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery
pack contains a small amount of harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
• Keep it away from children.
• Do not drop the battery pack.
Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery,
comply with local ordinances or regulations.
The battery pack should be stored at room temperature, charged to approximately 30 to 50% of
capacity. We recommend that battery pack be charged about once per year to prevent
overdischarge.
Danger of explosion if battery is incorrectly replaced.
When replacing the lithium coin cell battery, use only the same or an equivalent type that is
recommended by the manufacturer. The battery contains lithium and can explode if not properly
used, handled, or disposed of.
Do not:
• Throw or immerse into water
• Heat to more than 100°C (212°F)
• Repair or disassemble

Using headphones or earphones
CAUTION:
Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of
the equalizer to maximum increases the earphone and headphone output voltage and the sound
pressure level. Therefore, to protect your hearing, adjust the equalizer to an appropriate level.
Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the
output of the headphone or earphone connectors do not comply with specifications of EN 50332-2. The
headphone output connector of your computer complies with EN 50332-2 Sub clause 7. This specification
limits the computer’s maximum wide band true RMS output voltage to 150 mV. To help protect against
hearing loss, ensure that the headphones or earphones you use also comply with EN 50332-2 (Clause 7 limits)
for a wide band characteristic voltage of 75 mV. Using headphones that do not comply with EN 50332-2 can
be dangerous due to excessive sound pressure levels.
If your Lenovo computer came with headphones or earphones in the package, as a set, the combination of the
headphones or earphones and the computer already complies with the specifications of EN 50332-1. If
different headphones or earphones are used, ensure that they comply with EN 50332-1 (Clause 6.5 Limitation
Values). Using headphones that do not comply with EN 50332-1 can be dangerous due to excessive sound
pressure levels.

Connecting to the network
Your computer has one or more network cards for connecting to the Internet.
The Access Connections program or the Lenovo Settings program preinstalled on your computer is a
connectivity assistant program for creating and managing location profiles. Each location profile stores all the
network and Internet configuration settings needed for connecting to a network infrastructure from a specific
location such as a home or an office.
For more information, refer to the help information system of the program.
Ethernet connection
Your computer has one Ethernet connector. Using the connector and a wired cable, you can connect to your
network or a broadband connection, such as digital subscriber line (DSL) or cable television (CATV). This
connection enables you to do 1 Gbps half-duplex or full-duplex data transmission.
Wireless connection
Wireless communication is the transfer of data without the use of cables but by means of radio waves only.
Wireless LAN
A wireless LAN covers a relatively small geographic area, such as an office building or a house. Devices based
on the 802.11 standards can connect to this network.
Your computer comes with a build-in wireless network card and a configuration utility to help you make
wireless connections and monitor the status of your connection, so that you can stay connected to your
network while you are in the office, in a meeting room, or at home, with no need for a wired connection.
Only recharge the battery pack strictly according to instructions included in the product
documentation.
Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery,
comply with local ordinances or regulations and your company's safety standards.
There is a danger of an explosion if the backup battery is incorrectly placed. The lithium battery
contains lithium and can explode if it is not properly handled, or disposed of. Replace only with a
battery of the same type. To avoid possible injury or death, do not: (1) throw or immerse into water,
(2) allow it to heat to more than 100°C (212°F), or (3) attempt to repair or disassemble it. Dispose of it
as required by local ordinances or regulations and your company's safety standards.

Establishing a wireless connection
To establish a wireless connection, do the following:
1. Press Fn + F5 to turn on the wireless feature.
2. Click the wireless network connection status icon in the Windows notification area. A list of available
wireless networks is displayed.
3. Double-click a network to connect to it. Provide required information if needed.
To connect to different wireless networks in different locations, use the Access Connections program or the
Lenovo Settings program to manage multiple network profiles so that the computer connects to an available
network automatically when the location changes.
Using the NVIDIA Optimus Graphics feature
Depending on the model, your computer might support the NVIDIA Optimus Graphics feature.
To achieve the best balance between computer performance and battery life, depending on the graphics
quality demand of the running application and the settings of the power plan you use, the NVIDIA Optimus
Graphics feature automatically switches between High Performance Graphics and Energy Saving Graphics
with no need to restart your computer, close applications, or intervene manually.
Using a flash media card
Your computer has one media card reader slot. The media card reader slot supports the following types of
cards:
•Secure Digital (SD) card
•Secure Digital High Capacity (SDHC) card
•SD eXtended Capacity (SDXC) card
•MultiMediaCard (MMC)
Attention: While transferring data to or from a flash media card, such as an SD card, do not put your
computer into sleep or hibernation mode before the data transfer is complete; otherwise, your data could
become damaged.
Inserting a flash media card
Attention: Before you start installing any of the following cards, touch a metal table or a grounded metal
object. This action reduces any static electricity from your body. The static electricity could damage the card.
To insert a flash media card, do the following:
1. Ensure that the card is correctly oriented.
2. Insert the card firmly into the 4-in-1 media card reader slot. The card might stop before it is completely
installed into the slot.
Removing a flash media card
To remove a flash media card, do the following:
1. Push the flash media card until you hear a click.
2. Gently pull the flash media card out of the memory card slot.
Note: If you do not remove the card from your computer after you eject the card from the Windows operating
system, the card can no longer be accessed. To access the card, you must remove it once, then insert it again.
