FYI-- I have the APC travelpower adaptor which, unfortunately, does not have a tip for the 700m (as of feb. 05)-- but my old Targus PA-350 does have one available. It's #103, and I've tried it--works fine, but only to run the laptop, not to charge. However, I was able to simultaneously charge my other devices (phone & Palm) through the Dell's USB ports.
Apparently Targus has other newer models that work too. The PA-350 has both Empower and 12v dc plugs-- perfect for those AA exit rows. (APC charger works with those and from AC too--wish it matched my Dell. Come on APC, get with it.)
