FIRST THINGS FIRST
We would like to thank you for making this Acer desktop computer
your choice for meeting your computing needs.
Your guides
To help you use your Acer desktop computer, we have designed a set
of guides:
First off, the Setup Guide (or Setup Poster) helps you get started
with setting up your computer.
The Quick Guide introduces you to the basic features and functions
of your new computer. For more on how your computer can help you
to be more productive, please refer to the User’s Manual. This guide
contains detailed information on such subjects as system utilities, data
recovery, expansion options and troubleshooting.
To download the User’s Manual, you must first be connected to the
internet. Open Acer Care Center from the desktop and click on the
link under Support. The link will open the Acer Service & Support
webpage. Scroll down to Drivers and Manuals and search for your
model by entering the serial number, SNID, or product model. You
may also download and install the Acer identification tool that will
automatically detect this information and allow you to copy it to the
clipboard. Once you have found your product model, select
Documents and select your language to download the User’s
Manual.

8 - Connecting to the Internet
CONNECTING TO THE INTERNET
This chapter includes general information on types of connections,
and getting connected to the internet. Some of this information may
not apply to your computer. For detailed information, please refer to
Network connections on page 43.
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.
Acer computers feature an Airplane mode hotkey that turns the
network connection on or off. You can use the network management
Warning
Using wireless devices while flying in aircraft may be prohibited. All
wireless devices must be switched off before boarding an aircraft and
during take-off, as they may be dangerous to the operation of the
aircraft, disrupt communications, and even be illegal. You may turn on
your computer’s wireless devices only when informed that it is safe to
do so by the cabin crew.

Connecting to the Internet - 9
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). If you are
trying to connect to a public network (such as at a coffeeshop),
make sure you have the wireless network’s name.
2. In the icon tray in the lower right-hand corner of the screen, select
the Notifications icon to open the Notifications pane.
3. Select All settings.
Note
Please refer to your ISP or router documentation for details on connecting to
the internet.

BIOS UTILITY
The BIOS utility is a hardware configuration program built into your

Securing your computer - 15
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.
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 14.
• 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.
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.
Important
Do not forget your Supervisor Password! If you forget your password,
please get in touch with your dealer or an authorized service center.

16 - Securing your computer
• 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.

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. These checks will slowly
drain your computer’s battery.

environmental impact, turn off Fast startup:
1. Open the desktop.
2. Click Power Options in the Notification area.
3. Select More Power Options.
4. Select Choose what the power buttons do.

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).
