After pulling the battery and holding the power button (to drain any residual charge), if you've rebooted and it's still not shutting off completely, I'd look at all the apps she's installed since the problem started and start removing each app one at a time. I'm not sure if you can view the app list by date of install, but ask her which apps have recently been added and remove each one, also any files that she may have downloaded recently. Also if she has Wifi tethering on, there's an "Always on" setting, although that shouldn't keep the display on. If all else fails, she's probably looking at doing a wipe/restore on her phone.
