At least on Debian the system resumes once you plug in the external power 
so you would have to do that before suspending. I already took the battery 
out while the Neo was on usb power and it still ran - but I didn't re-
insert it then (because I was intending a "hard" reboot ;) ) so I don't 
know if that could damage anything.
