Jane:Eric, can you help me with my computer? There's something wrong with it.
Eric:Sure, what's the problem?
Jane:When I turn on the computer it starts up normally, but then it just shuts down again.
Eric:Hmm. Do any error messages show up?
Jane:No, it just suddenly shuts down.
Eric:I'd better check it out. I'll have some time later on today, but in the meantime you can use one of the spare laptops
