Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a
hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact
the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the
AC adapter comply with the user-accessible surface temperature limits defined by the International
Standard for Safety of Information Technology Equipment (IEC 60950).

network
Using wireless devices (select models only)
Wireless technology transfers data across radio waves instead of wires. Your computer may be
equipped with one or more of the following wireless devices:
WLAN device—Connects the computer to wireless local area networks (commonly referred to as
●
Wi-Fi networks, wireless LANs, or WLANs) in corporate offices, your home, and public places such
as airports, restaurants, coffee shops, hotels, and universities. In a WLAN, each mobile wireless
device communicates with a wireless router or a wireless access point.
HP Mobile Broadband Module—A wireless wide area network (WWAN) device that provides
●
access to information wherever mobile network operator service is available. In a WWAN, each
mobile device communicates to a mobile network operator’s base station. Mobile network operators
install networks of base stations (similar to cell phone towers) throughout large geographic areas,
effectively providing coverage across entire states, regions, or even countries.
Bluetooth device—Creates a personal area network (PAN) to connect to other Bluetooth-enabled
●
devices such as computers, phones, printers, headsets, speakers, and cameras. In a PAN, each
device communicates directly with other devices, and devices must be relatively close together—
typically within 10 meters (approximately 33 feet) of each other.
Computers with WLAN devices support one or more of the following IEEE industry standards:
802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a
●
frequency of 2.4 GHz.
802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g
●
WLAN device is backward compatible with 802.11b devices, so they can operate on the same
network.
802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.
●
NOTE: 802.11a is not compatible with 802.11b and 802.11g.
802.11n supports data rates of up to 450 Mbps and may operate at 2.4 GHz or 5 GHz, making it
●
backward compatible with 802.11a, b, and g.
NOTE: The specifications for the 802.11n WLAN are draft specifications and are not final. If the
final specifications differ from the draft specifications, it may affect the ability of the computer to
communicate with other 802.11n WLAN devices.

Help and Support.

Using the wireless controls
You can control the wireless devices in your computer using these features:
Wireless button or wireless switch (referred to in this guide as the wireless button)
●
Wireless Assistant software (select models only)
●
HP Connection Manager software (select models only)
●
Operating system controls
●
Using the wireless button
The computer has a wireless button, one or more wireless devices, and one or two wireless lights,
depending on the model. All of the wireless devices on your computer are enabled at the factory, so the
wireless light is on (white) when you turn on the computer.
The wireless light indicates the overall power state of your wireless devices, not the status of individual
devices. If the wireless light is white, at least one wireless device is on. If the wireless light is off, all
wireless devices are off.
Indicates that one or more of your network drivers are installed, all
network devices or all wireless devices are disabled in Windows
Control Panel, and no network devices are connected to a wired
network.
Using wireless devices (select models only) 17
Because the wireless devices are enabled at the factory, you can use the wireless button to turn on or
turn off the wireless devices simultaneously. Individual wireless devices can be controlled through
Wireless Assistant software (select models only) or through Computer Setup.
NOTE: If the wireless devices are disabled by Computer Setup, the wireless button will not work until
you reenable your devices.
Using Wireless Assistant software (select models only)
A wireless device can be turned on or off using the Wireless Assistant software. If a wireless device is
disabled by Computer Setup, it must be reenabled by Computer Setup before it can be turned on or off
using Wireless Assistant.
NOTE: Enabling or turning on a wireless device does not automatically connect the computer to a
network or a Bluetooth-enabled device.
To view the state of the wireless devices, click the Show hidden icons icon, the arrow at the left of the
notification area, and position the cursor over the wireless icon.
If the wireless icon is not displayed in the notification area, complete the following steps to change the
Wireless Assistant properties:
1. Select Start > Control Panel > Hardware and Sound > Windows Mobility Center.
2. Click the wireless icon in the Wireless Assistant tile, which is located in the bottom row of Windows
Mobility Center.
3. Click Properties.
4. Select the check box next to HP Wireless Assistant icon in notification area.
5. Click Apply.
6. Click Close.
For more information, refer to the Wireless Assistant software Help:
1. Open Wireless Assistant by clicking the wireless icon in Windows Mobility Center.
2. Click the Help button.
Using HP Connection Manager (select models only)
You can use HP Connection Manager to connect to WWANs using the HP Mobile Broadband device in
your computer (select models only).
To start Connection Manager, click the Connection Manager icon in the notification area, at the far
right of the taskbar.
