Tonight, after two hours spent carefully designing an ad, my laptop suddenly turned itself off - result: all work lost as I was just about to save it but hadn't. As the laptop works with battery power, I'm busy saving files to a disc just in case. It's not the fuse, so I can only presume the charger overheated or somesuch. Not sure if temporary or permanent.

Anyway, if e-mails don't get answered etc, this will be why. Normal service will be resumed, probably just after the nick of time if this is anything to go by...
