Message-ID: <3226@tekgen.BV.TEK.COM> Date: 13 Jul 88 20:15:06 GMT Organization: Tektronix Inc., Beaverton, Or. Lines: 22 My question concerns devices such as PC's and laser printers that have both electronic _and mechanical_ components. To maximize their life expectancy, when should they be turned off? At the end of every day? For weekends only? Only when they will be out of use for a week or more? Never?? (As I understand it, the issue is as follows. Electronic components suffer most of their wear when they are powered-up. Therefore, the longest life can be realized by never turning them off. Exception -- damaging power surges. On the other hand, mechanical components, such as hard disk drives, wear out as a function of total hours of use.) I have asked some people around the company and have received _opinions_ in all of the above categories. I don't think that more _opinions_ will help decide this issue. However, if you have some facts/data, I think a lot of people would be interested in hearing from you on this matter. I know that I would.
