Thanks for your very helpful reply.
I will get a UPS, as you suggest, and if I can locate an APC I'll get that.

I hadn't really thought about the last part;
but of course it is not normally sufficient just to switch the current on,
I have to press the button on the computer as well.
The computer in question is an HP MicroServer;
I will see if it is possible to send it into halt mode.
