Does my T400 have Bluetooth?

Does my 2767-DR4 with WinXP SP3 have Bluetooth?


My Device Manager shows 'Bluetooth Bus Enumerator', and i can start the Bluetooth Service. But bthprops.cpl does nothing, the Bluetooth icon in the taskbar says 'Bluetooth device not found', and the Control Panel Bluetooth Configuration does nothing when I start it.

Re: Does my T400 have Bluetooth?

Thx for the replies. I finally saw a post that mentioned the BIOS, so I checked and my bluetooth I/O was turned off there. So after turning it on, I was able to see Bluetooth in Fn-F5 and use my new mouse.
