How does Microsoft Streets and Trips handle a planned route if computer shut down?
How does Microsoft Streets and Trips handle negotiating a planned route if the computer is shut down during a stop? Is it necessary to delete stops as one completes them, or when you restart the computer and reload the route will the GPS simply continue routing you to the next destination?
Streets & Trips will pick up mid-route -- selecting the segment that is closest to the current GPS location. There can be some problems if you're far off-route or if your route backtracks, but I haven't found it to be too big of a problem.

Of course, deleting points will cause the software to do a better job. Also, I always hibernate my laptop when I'm on the road. I only shut down when I'm on AC power.
You want to save the route file before you shut down the computer. [ctrl-s].

You do not need to delete negotiated stops; just keep going. This will create a record of your trip fwiw.
Thanks, those are excellent suggestions. Of course I should have thought about the hibernation option, but wonder about the amount of draw on the vehicle battery. Our stops vary from 15 minutes (taking a photo of a church or courthouse) to 2 hours (touring some past president's home). Would this be a problem when using a netbook?
As hibernation backs up everything to the hard drive and shuts off the computer, power draw would be battery charge only. You could actually unplug the computer without any adverse effect to the hibernation cycle. Of course, this is also true for sleep (standby in XP) where the memory state is maintained by external power - as the computer is powered from its own batteries anyway.

The difference is the hibernation cycle would survive a failure of the laptop's batteries to maintain sufficient power whereas Standby would not. Hardly an issue if it isn't off for 24 hours or more.

My Acer netbook came with a three-cell battery. I significantly improved the battery life by purchasing a six-cell battery for it. I have no concerns about simply closing the lid (puts it to sleep) and leaving it sit on battery overnight. Closing the lid and leaving it sit for two hours, unplugged, would not concern me in the least, especially if it's going to start recharging immediately that you start the vehicle again.

I think my six-cell battery was around $40. A very worthwhile investment, in my view. If yours already has one (some come standard that way), you're golden.

First off if your laptop drains your car battery in hibernation mode, even if left over night, it's time to go get a new battery.
I leave my laptop, Toshiba NB200, in hibernation mode all the time, too lazy to wait for it to boot up, most of the time unplugged. Never have a problem with battery life so far.
In my understanding of laptop computer hibernation modes, there is no power draw beyond the laptop's own battery. Therefore, there is no risk of a hibernating laptop draining a host vehicle's battery. But just to be safe if you have any concerns in this regard, unplug the laptop.
