For a while now, I have wondered how to turn off the WWAN and Bluetooth radios in my x60.

Thanks to a program manager who finally asked the question, and to the Lenovo System Engineer who answered, I now know the secret. And I'm sharing with you.

If your system is up-to-date with System Update, you can press Fn-F5 to bring up the "Radio Dashboard" and control the status of all 3 radios in an x60T.

I wonder if turning off WWAN and Bluetooth will significantly impact my battery life, which currently hovers around 3 hours (full brightness, WLAN on).

I am assuming battery life will improve, perhaps by an hour, given the presumed power consumption of two radio transmitters.
