Using the wireless key
The computer has a wireless key, one or more wireless devices, and one or two wireless lights,
depending on the model. All of the wireless devices on the computer are enabled at the factory, so the
wireless light illuminates 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 illuminates white, at least one wireless device is on. If the wireless light
illuminates amber, all wireless devices are off.
Because the wireless devices are enabled at the factory, use the wireless key to turn on or turn off the
wireless devices simultaneously. Individual wireless devices are controlled through HP Wireless
Assistant.
Using HP Wireless Assistant
A wireless device is turned on or off using HP Wireless Assistant. If a wireless device is disabled by
Setup Utility, it must be re-enabled by Setup Utility 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 mouse pointer over the wireless icon.
If the wireless icon is not displayed in the notification area:
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. Wireless Assistant appears.
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, see the Wireless Assistant software Help. To access Help:
1. Open Wireless Assistant by clicking the Wireless icon in Windows Mobility Center.
2. Click the Help button.
