Bad air conditioning and no-reset-key on the IBM PCs favor frequently power-downs. But, the harm in power-downs seems to be the spikes and voltage transients originating from or harming the power supply. But what if the electrical lines are conditioned and free of spikes and transients? Then would it be safe(r) to power down often? Many sites have conditioned lines, and many micros are equipped with electronic filters. The implied culprit is a trashy power supply (is there no such thing as clean power?). Now, we have time to talk about questions like power-down sequences. Which one do you turn off/on first -- CRT, disk, computer, modem, ... -- and what effect does it have on the equipment?
