Tell her to just turn it off, leave the battery in.
The battery will slowly discharge but it can take a stupidly long time. I've got a netbook I use occasionally, and I've left it off and not-plugged for many weeks at a time and it still has some charge when I get around to it.
If she's really worried, off+plugged will trickle-charge the battery, keeping it constantly topped up and will only put minimal wear on it.
A more serious concern is updates. As part of her pre-travel preparation, tell her that when she's making sure the battery's charged, she also makes sure to run all the updates (Windows or otherwise) before traveling - and that includes (in Windows' case anyways) doing another boot/shutdown to make sure everything's okay.
And if she wants speedy access while travelling, she can boot it up, close the lid to sleep it, and she's fine. It should take many hours for the laptop to run down the battery on standby (usually 3-4hh for every 1h of normal runtime).
