After forgetting to turn the wireless card on a notebook back on after a battery streching train journey, I discovered the Windows Mobility Centre. This is a very useful collection of settings likely to be needed by notebook owners.

Of note to me is the ability to turn wireless networking off to save battery power but it is also a quick way to change the power scheme and volume.

There is a fly in the ointment, no shortcut key that I know off. There might be as I first saw the Mobility Center appear when my 18 month old daughter was let loose on the keyboard. She's not telling me what she pressed though so I'll have to find out for myself.
