serial number and SNID and allow you to copy it to the clipboard.
4. Once you have found your product model, any updates, or
documents will be listed.

Taking care of your AC adapter
Here are some ways to take care of your AC adapter:
• Do not connect the adapter to any other device.
• Do not step on the power cord or place heavy objects on top of it.
Route the power cord and any cables away from where people walk.
• When unplugging the power cord, do not pull on the cord itself but
pull on the plug.
• The total ampere ratings of the equipment plugged in should not
exceed the ampere rating of the cord if you are using an extension
cord. Also, the total current rating of all equipment plugged into a
single wall outlet should not exceed the fuse rating.

Connecting to the Internet - 11
CONNECTING TO THE INTERNET
This chapter includes general information on types of connections,
and getting connected to the internet. For detailed information, please
refer to Network connections on page 38.
Your computer’s built-in network features make it easy for you to
connect your computer to the internet using a cable or a wireless
connection.
First though, in order to connect to the internet, you’ll need to sign up
for internet services from an ISP (Internet Service Provider) -- usually
a phone or cable company -- that will have to go to your home or
office to set up internet service. The ISP will install a small box, a
router or modem, that will allow you to connect to the internet.
Connecting to a wireless network
Connecting to a wireless LAN
A wireless LAN (or WLAN) is a wireless local area network, which can
link two or more computers without using wires. Once connected to
WLAN, you can access the internet. You can also share files, other
devices, and even your internet connection itself.
Your computer's wireless connection is turned on by default and
Windows will detect and display a list of available networks during
setup. Select your network and enter the password if required. You
can use the network management options to turn your wireless
network on/off or control what is shared over the network.
To connect to a wireless network, please follow the steps below.
1. Ensure you have a wireless router/access point and current internet
connection through the ISP of your choice. Make a note of the
wireless network’s name and password (if necessary).
Note
Please refer to your ISP or router documentation for details on connecting to
the internet.

12 - Connecting to the Internet
2. Click Network icon in the notification area.
3. You will see a list of available wireless networks. Select the one you
wish to use.
4. Once you select a wireless network, select Connect.
5. If required, enter the network’s password.
Connecting with a cable
Built-in network feature
If your computer has a network port, plug one end of a network cable
into the network port on your computer, and the other end into a port
on your router (refer to the image below.) Then, you'll be ready to get
online.
Note
If Wi-Fi is turned off, please click Wi-Fi tile to turn it on.

Keeping your computer
and data safe...
In this section you will find:
• How to secure your computer
• Setting passwords

14 - Securing your computer
SECURING YOUR COMPUTER
Your computer is a valuable investment that you need to take care of.
Learn how to protect and take care of your computer.
Security features include hardware and software locks — a security
notch and passwords.
Using a computer security lock
The computer comes with a computer security slot for a security lock.
Wrap a computer security lock cable around an immovable object
such as a table or handle of a locked drawer. Insert the lock into the
notch and turn the key to secure the lock. Some keyless models are
also available.
Using passwords
Passwords protect your computer from unauthorized access. Setting
these passwords creates several different levels of protection for your
computer and data:
• Supervisor Password prevents unauthorized entry into the BIOS
utility. Once set, you must enter this password to gain access to the
BIOS utility. See Setting passwords on page 16.
• User Password secures your computer against unauthorized use.
Combine the use of this password with password checkpoints on
boot-up and resume from Hibernation (if available) for maximum
security.
• Password on Boot secures your computer against unauthorized
use. Combine the use of this password with password checkpoints
on boot-up and resume from Hibernation (if available) for maximum
security.
Important
Do not forget your Supervisor Password! If you forget your password,
please get in touch with your dealer or an authorized service center.

Securing your computer - 15
Entering passwords
When a password is set, a password prompt appears in the center of
the display screen.
• When the Supervisor Password is set, a prompt appears when you
enter the BIOS utility.
• Type the Supervisor Password and press Enter to access the BIOS
utility. If you enter the password incorrectly, a warning message
appears. Try again and press Enter.
• When the User Password is set and the password on boot
parameter is enabled, a prompt appears at boot-up.
• Type the User Password and press Enter to use the computer. If
you enter the password incorrectly, a warning message appears. Try
again and press Enter.
Important
You have three chances to enter a password. If you fail to enter the
password correctly after three tries, the system halts. Press and hold
the power button for four seconds to shut down the computer. Then
turn on the computer again, and try again.

16 - BIOS utility
BIOS UTILITY
The BIOS utility is a hardware configuration program built into your
computer's BIOS.
Your computer is already properly configured and optimized, and you
do not normally need to run this utility. However, if you encounter
configuration problems, you may need to run it.
To activate the BIOS utility, press F2 while the computer logo is being
displayed.
Boot sequence
To set the boot sequence in the BIOS utility, activate the BIOS utility,
then select Boot from the categories listed on the top of the screen.
Setting passwords
To set a password on boot, activate the BIOS utility, then select
Security from the categories listed on the top of the screen.
Find Set Supervisor Password and enter a password to enable this
feature. Once you have entered a password for this feature, you may
then enable/disable Password on Boot.
Remember to select F10 to properly save and exit the BIOS utility
when you are done making changes.

Power management - 17
POWER MANAGEMENT
This computer has a built-in power management unit that monitors
system activity. System activity refers to any activity involving one or
more of the following devices: keyboard, mouse, hard disk,
peripherals connected to the computer, and video memory. If no
activity is detected for a period of time, the computer stops some or all
of these devices in order to conserve energy.
Saving power
Disable Fast startup
Your computer uses Fast startup to start quickly, but also uses a small
amount of power to check for signals to start.
If you prefer to reduce your computer’s power requirements and
environmental impact, turn off Fast startup:
1. Press the Windows key or select the Windows Start button then
select Settings > System > Power & sleep.
2. Select Choose what the power buttons do.
3. Select Change settings that are currently unavailable.
4. Scroll down and disable Turn on fast startup.
5. Select Save changes.
Note
If Fast startup is off, your computer will take longer to start from Sleep.
Your computer will also not start if it receives an instruction to start over a
network (Wake on LAN).
