Tell her to try pressing CTRL, ALT and the Up Arrow keys simultaneously. That will fix it if its a GMA 950 powered laptop.
Edit- Well, thats a general statement but those are the default hotkeys for display rotation that come with the GMA 950 Drivers. If it doesn't do anything, next port of call is Control Panel, and look for the graphics settings. Rotation should be controllable from there, and that will apply to most all graphics cards.
