It froze up, didn’t want to shut off, and now won’t reboot. I emailed DP to see if he has any ideas.
What happens when she tries to boot it? How far before it hangs, or displays error messages, or whatever?
Either that, or press and hold the power button for a slow 10 count.
As long as it was only a software issue, it should come back up ok. If MS wants to check the file system prior to logging in, have it do so.
