The main issue in my mind would be the power draw. Depending on the
machines, that could be anywhere from 25W to 60W. You might get a
killawatt[0] and measure the draw. Do these machines not have a
suspend or sleep option? Can these lawyers not use the boot time as an
excuse to walk over for coffee or tea or whatever?

Cheers,

Coleen: I second Cristóbal's observation above. Depending on which OS and version you have, you likely have the option to hibernate, suspend, standby, and/or sleep on each machine. If you use one of these options, you will save most of the power of a shutdown, but the machines will restart much faster.

In overly general terms, standby and suspend are low-power states that consume much less power, but do not turn the machine fully off.

Hibernate turns the power fully off, but saves the state of your applications to disk first. When you power back up, the computer bypasses the usual OS boot and reloads the saved state from where it was suspended. This takes a little longer but saves more energy.

"Sleep" is harder to quantify, since it has been used for different purposes on different operating systems. Most descriptions make it sound similar to standby or suspend.

I recommend giving the available options a try on the various systems involved, you can save power and reduce bootup waiting.
