$15/mo/computer seams to be pretty high. But I don't know your electric rates, what is it per Kilowatt-Hour (kWhr). The ongoing heat might depending on the design degrade the plastic parts. It is actually the inrush current that kills the most electronic parts during power on. The bearings of the hard drives shouldn't represent a problem it is a more likely problem that the read/write heads stick to the disk during power off which get damaged during power on. I have 5 desktop PC's running at my friends company for over 11 years 24/7/365 without any problems. I bet you, that if they would have switched them of every day they all would have gone broke for one or the other reason mostly for electronic failure due to the inrush current.

Or is the most wear due to the surge of power when you turn it on and the stress on the bearings on the hard drive? I turn off my computers at night (actually go to standby so they start faster). I once figured it saved about $15/mo/computer to turn them off a night but San Diego has pretty high electric rates.

It's using the power supply, of course, not the battery. Is there a down side to this? will the machine wear out more quickly because of this? Even though it's a notebook, I rarely move it, so I just leave it running.
