If this book were about troubleshooting a computer that isn’t turned on, it would be a very short book. That’s because, when a PC is turned off, it performs quite reliably. After power is supplied, however, trouble looms like a flatbed truck loaded with loosely packed logs on a bumpy road.

To best understand PC startup problems, this chapter walks you through the power-on process, from electronic slumber to electron-invigorated operation. When you appreciate the computer’s power-on sequence, though it may be technical, you can better pinpoint a problem and address specific issues.
