When I was a senior in High School I worked evenings at a call center fielding extended warranty repair calls for a major retail chain. There were many calls about older Macintosh computers that would not turn on. Some would give the chime, others would not, but they all stopped before video initialized. The standard procedure was to send out a replacement motherboard (refurb from a contracted parts warehouse). These replacements would often suffer the same failure within days of being installed, if not immediately. No one in the call center seemed to know the problem. I knew a little trick from my days in the school Mac Lab. I would have the customer flip the power switch, wait ten seconds, then flip it off and back on again (not too quickly). Often I would have the customer stand up and spin around or some other humorous ruse before the second step. The Macintosh would boot up and work fine. I would order a new motherboard battery ($2.50) and the retailer would pay 75 bucks for a tech to go install it. Still much cheaper than what they were doing before.
