HP Headset not working

SOURCE: help! I've no idea!

fold the boom up, push and hold down the central button until it turns violet, open the boom and then let up on the button. The central button should stay violet without blinking. Then go through the pairing routine on your phone.

Sounds like you've got a defective model. Mine lasts about 4-5 days before I have to charge it.

I had the same problem. It does seem to be related to the battery. The solution--in my case--was to recharge the headset until the light turned green again and then flip it open and it hooked up again.

SOURCE: Motorola S805 headset worked fine with T60 laptop

Solution I found with the same devices is to properly par the devices.

Refer http://direct.motorola.com/ens/s805/QuickstartGuide.pdf

It basically states :

1.Ensure the headphones are turned off (L indicator light not blinking).
2.Press and hold L button. After about 6 seconds, the L indicator light becomes steadily lit.
3.Release the L button. The L indicator light remains steadily lit.

If the L indicator light is flashing or not steadily lit, repeat steps 1 through 3

Now on the T60:

Search for Bluetooth Devices as you would normally.
The T60 lists Bluetooth devices it finds.
Select Motorola S805.
Select OK or Yes to pair your headphones
with your phone.
Enter the passkey: 0000
Select OK.
When your headphones successfully pair
with your phone, the L indicator light
changes from steadily lit to rapidly flashing.

That's it next time you start a audio program on T60 output will be sent to Motorola Headphones

SOURCE: I have a H270 Bluetooth headset. I charged it

I had the same problem. I plugged a USB charger into the headset and turned the power switch off. It worked as normal after that. I think it does not like to be "on" when the USB is disconnected. Anyway it seems the plugging/unplugging kick-started it.
