Pairing the Plantronics Explorer 220:

For most phones, select Settings/Tools, Connections, Bluetooth, On. See your phone's user guide for more information.

With the 220 headset powered off, turn on the headset by pressing and holding the call control button for approximately 5 seconds until the LED flashes red & blue. The Explorer 220 headset is now in pairing mode. If you don't see the red/blue flash, press and hold the power button to turn your headset off, and then press and hold the power button again and hold for 5-6 seconds until you see the red & blue flash.

From your phone, go to the Bluetooth menu and select "Search" or "Add Device". Your phone should find the headset which will appear as "2xxPlantronics" in your list of devices.

If prompted for the Passkey (PIN code), enter 0000. If your phone asks for a PIN/passkey, enter 0000 (4 zeros). Pairing is successful when the LED on your headset flashes blue. Your headset is now connected and ready to use.

Try this to see if can give us some codes with it's on board diagnostics. Hold down the function button of your laptop and then the power button while still holding down the Fn/Function button on the left side of the keyboard. See if this gives you either an error message on your screen or, flashing lights above your keyboard. Pay attention, write down what lights where lit up what ones flashed, etc. This is to diagnose if the LCD isn't working. Comment back if you get either the light code or the error code on the screen. IF nothing happens try holding the Fn/Function button on the left side of keyboard and holding the F4 button, see if that makes any lights flash above your keyboard.

Hi
Go to Control Panel, Power Options,
Then adjust the options there:

• closing screen behavior,
• pressing the power button behavior

and, tell us the results.
Good Luck
