Re: Can you hold down the power button
Agreed. The issue here was miscommunication - the woman obviously didn't know much about computers, but she did know how to turn one off and on again - she just didn't understand what she was being asked to do. I suspect a simplification of language could have saved our hero 30 minutes of free time.
That said, sacking her for being a dingbat would seem like a sensible solution too - after all if she's this challenged at one thing, she's probably this challenged at many others too.
