Lenovo Thinkpad T30 & Bluetooth
I've just spent the last 3 hours taking a Lenovo Thinkpad T30 apart in order to fit the bluetooth antenna and daughter card only to find that it won't work because this model doesn't have the bluetooth power switch!!!
I'm now in the process of buying a USB Bluetooth dongle. It'll be a million times easier to fit and can be used in more than one unit.
Final word: Don't even think about upgrading your Lenovo Thinkpad T30 to Bluetooth using the internal upgrade route!
