Bluetooth connections allow devices to connect without the use of wires or cables. Some users of the Sony Vaio laptop computer have encountered problems with the connection of Bluetooth devices with their computer. The problem lies with turning on the Vaio's Bluetooth function. This is turned on through the computer's Wireless Switch Settings manager. The icon for this is in the system tray in the taskbar when the computer is first purchased.
Double-click the "Wireless Switch Settings" icon in the system tray of the taskbar. It is a a blue-green icon with "LAN" in one corner and "B" in the other.
Check the "Enable Bluetooth Device" setting in the Bluetooth Device section.
If the device was already enabled, change the wireless LAN from "2.4GHz" to "5GHz" because, as the warning message should say, using the 2.4GHz wireless LAN and the Bluetooth device can make the connection unstable.
Click the "Apply" button after the appropriate boxes are checked to activate the Bluetooth signal. A blue light should come on near the computer's on/off switch for the Wi-Fi radio.
Click "OK." Another dialog box should appear explaining that the Wireless Switch Settings icon should now be in the taskbar. Use this icon if you need to turn off or on the Bluetooth device in the future.
