This is a question that has been bugging me for a long time. I have fixed a whole variety of machines. Air conditioners, ice machines, printers, lifts, scanners, labelers, packaging machines...the list is endless...and of course your own laptop. And as we all know, when the machine just won't do what it should, like get onto the web, and you checked everything else, modem is working, reset it, cables all good, no software conflict you can find...can't find any cause...so you finally decide, well, maybe I'll just try restart. And low and behold it works. Now, this works on all these machines time and time again. There has to be a common reason. And you feel feel like an idiot just having to restart again and act like you know what you are doing without really understanding the exact cause. What is the exact cause? Is it the capacitors? Do they need to be relieved? What is going on? Do you see what I am getting at? We've all seen this surely. Why do all machines do this crap?
