"reboot" | "shutdown" from the command line.

Hold Alt+PrtSc keys and press in order, r e i s u b. This will safely shutdown and reboot your PC.

Thanks - that worked fine!

In the old days I would have

sync;sync;shutdown now

but these days I avoid all of that old stuff.
I fear it has been half eleminated.
