No, there isn't a way to control it whatsoever. You will need to buy a wired keyboard and mouse. Yes, these things aren't obsolete at all. Look in most grocery stores, offices, banks, etc. They all use them. If it has a touch screen, that doubles as a mouse, however nothing replaces typing input as efficiently. Plus, if you used a cli (command line interface), you cannot use a mouse or touch input device.
I guess it's a lesson learned. Have a spare keyboard and mouse that doesn't rely on a dongle, or you're screwed. Use the laptop until she gets back.
