Using power-saving states
The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
When Sleep is initiated, the power light blinks and the screen clears. Your work is saved to memory,
letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended
period or if the battery reaches a critical battery level while in the Sleep state, the computer initiates
Hibernation.
When Hibernation is initiated, your work is saved to a hibernation file on the hard drive and the computer
turns off.
CAUTION: To prevent possible audio and video degradation, loss of audio or video playback
functionality, or loss of information, do not initiate Sleep or Hibernation while reading from or writing to
a disc or an external media card.
NOTE: You cannot initiate any type of networking connection or perform any computer functions while
the computer is in the Sleep state or in Hibernation.
Initiating and exiting Sleep
The system is set at the factory to initiate Sleep after 15 minutes of inactivity when running on battery

Using battery power
When a charged battery is in the computer and the computer is not plugged into external power, the
computer runs on battery power. When the computer is plugged into external AC power, the computer
runs on AC power.
If the computer contains a charged battery and is running on external AC power supplied through the
AC adapter, the computer switches to battery power if the AC adapter is disconnected from the
computer.
NOTE: The display brightness is decreased to save battery life when you disconnect AC power. To
increase display brightness, use the f4 key or reconnect the AC adapter.
You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery
in the computer whenever the computer is plugged into AC power charges the battery and also protects
your work in case of a power outage. However, a battery in the computer slowly discharges when the
computer is off and unplugged from external power.
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.

30 Chapter 3 Wireless and local area network
Using a WLAN
With a WLAN device, you can access a wireless local area network (WLAN), which is composed of other
computers and accessories that are linked by a wireless router or a wireless access point.
NOTE: The terms wireless router and wireless access point are often used interchangeably.
A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points
●
that can accommodate a large number of computers and accessories and can separate critical
network functions.
A home or small office WLAN typically uses a wireless router, which allows several wireless and
●
wired computers to share an Internet connection, a printer, and files without requiring additional
pieces of hardware or software.
NOTE: To use the WLAN device in your computer, you must connect to a WLAN infrastructure
(provided through a service provider or a public or corporate network).
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an
●
Internet service provider (ISP)
A wireless router (purchased separately) (2)
●
The wireless computer (3)
●
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.
For help in setting up your WLAN, refer to the information provided by your router manufacturer or your
ISP.
Protecting your WLAN
Because the WLAN standard was designed with only limited security capabilities—basically to foil casual
eavesdropping rather than more powerful forms of attack—it is essential to understand that WLANs are
vulnerable to well-known and well-documented security weaknesses.
WLANs in public areas, or “hotspots,” like coffee shops and airports may not provide any security. New
technologies are being developed by wireless manufacturers and hotspot service providers that make
the public environment more secure and anonymous. If you are concerned about the security of your
computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.
Using a WLAN 31
When you set up a WLAN or access an existing WLAN, always enable security features to protect your
network from unauthorized access. The common security levels are Wi-Fi Protected Access (WPA) and
Wired Equivalent Privacy (WEP). Because wireless radio signals travel outside the network, other WLAN
devices can pick up unprotected signals and either connect to your network (uninvited) or capture
information being sent across it. However, you can take precautions to protect your WLAN:
Use a wireless transmitter with built-in security
●
Many wireless base stations, gateways, and routers provide built-in security features such as
wireless security protocols and firewalls. With the correct wireless transmitter, you can protect your
network from the most common wireless security risks.
Work behind a firewall
●
A firewall is a barrier that checks both data and requests for data that are sent to your network and
then discards any suspicious items. Firewalls are available in many varieties, both software and
hardware. Some networks use a combination of both types.
Use wireless encryption
●
A variety of sophisticated encryption protocols is available for your WLAN. Find the solution that
works best for your network security:
Wired Equivalent Privacy (WEP) is a wireless security protocol that uses a WEP key to
◦
encode or encrypt all network data before it is transmitted. Usually, you can allow the network
to assign the WEP key. Alternatively, you can set up your own key, generate a different key,
or choose other advanced options. Without the correct key, others will not be able to use the
WLAN.
WPA (Wi-Fi Protected Access), like WEP, uses security settings to encrypt and decrypt data
◦
that is transmitted over the network. However, instead of using one static security key for
encryptions as WEP does, WPA uses temporal key integrity protocol (TKIP) to dynamically
generate a new key for every packet. It also generates different sets of keys for each computer
on the network.
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is on. If it is on, the wireless light is on. If the wireless light is amber,
slide the wireless switch.
NOTE: On some models, the wireless light is amber when all wireless devices are off.
2. Click the network icon in the notification area, at the far right of the taskbar.
3. Select your WLAN from the list, and then type the network security key, if required.
If the network is a security-enabled WLAN, you are prompted to enter a network security key, which
is a security code. Type the code, and then click OK to complete the connection.
NOTE: If no WLANs are listed, you are out of range of a wireless router or access point.
NOTE: If you do not see the network you want to connect to, click Open Network and Sharing
Center, and then click Set up a new connection or network. A list of options is displayed. You
can choose to manually search for and connect to a network, or to create a new network connection.
32 Chapter 3 Wireless and local area network
After the connection is made, place the mouse pointer over the network icon in the notification area, at
the far right of the taskbar, to verify the name and status of the connection.
NOTE: The functional range (how far your wireless signals travel) depends on WLAN implementation,
router manufacturer, and interference from other electronic devices or structural barriers such as walls
and floors.
More information about using a WLAN is available through the following resources:
Information from your ISP and the manufacturer's instructions included with your wireless router
●
and other WLAN equipment
Information and Web site links provided in Help and Support
●
For a list of public WLANs near you, contact your ISP or search the Web. Web sites that list public
WLANs include Cisco Internet Mobile Office Wireless Locations, Hotspotlist, and Geektools. Check with
each public WLAN location for cost and connection requirements.
For additional information on connecting your computer to a corporate WLAN, contact your network
administrator or IT department.
Roaming to another network
When you move your computer within range of another WLAN, Windows attempts to connect to that
network. If the attempt is successful, your computer is automatically connected to the new network. If
Windows does not recognize the new network, follow the same procedure you used initially to connect
to your WLAN.
Using a WLAN 33
Using HP Mobile Broadband (select models only)
HP Mobile Broadband enables your computer to use wireless wide area networks (WWANs) to access
the Internet from more places and over larger areas than it can by using WLANs. Using HP Mobile
Broadband requires a network service provider (called a mobile network operator), which in most cases
is a mobile phone network operator. Coverage for HP Mobile Broadband is similar to mobile phone voice
coverage.
When used with mobile network operator service, HP Mobile Broadband gives you the freedom to stay
connected to the Internet, send e-mail, or connect to your corporate network whether you are on the
road or outside the range of Wi-Fi hotspots.
HP supports the following technologies:
HSPA (High Speed Packet Access), which provides access to networks based on the Global
●
System for Mobile Communications (GSM) telecommunications standard.
EV-DO (Evolution Data Optimized), which provides access to networks based on the code division
●
multiple access (CDMA) telecommunications standard.
You may need the HP Mobile Broadband Module serial number to activate mobile broadband service.
The serial number is printed on a label inside the battery bay of your computer.
Some mobile network operators require the use of a subscriber identity module (SIM). A SIM contains
basic information about you, such as a PIN (personal identification number), as well as network
information. Some computers include a SIM that is preinstalled in the battery bay. If the SIM is not
preinstalled, it may be provided in the HP Mobile Broadband information provided with your computer
or the mobile network operator may provide it separately from the computer.
For information on inserting and removing the SIM, refer to the “Inserting a SIM” and “Removing a SIM”
sections in this chapter.
For information on HP Mobile Broadband and how to activate service with a preferred mobile network
operator, refer to the HP Mobile Broadband information included with your computer. For additional
information, see the HP Web site at

through which other computers may connect to the Internet. When two or more computers are connected
using Bluetooth, and Internet Connection Sharing (ICS) is enabled on one of the computers, the other
computers may not be able to connect to the Internet using the Bluetooth network.
The strength of Bluetooth is in synchronizing information transfers between your computer and wireless
devices including cellular phones, printers, cameras, and PDAs. The inability to consistently connect
two or more computers to share the Internet through Bluetooth is a limitation of Bluetooth and the
Windows operating system.
