Windows/Bootcamp power management

I'm using Bootcamp and Windows XP on a MPB (with AC power) to run a program that can't have a power slowdown or interruption. What's controlling it? I set the Power Settings in XP to keep everything on when plugged in, but it still shut down after about 15 minutes (I think it was the same as my XP battery power setting).

Does XP think I'm running on battery even when the MBP is plugged in. Or is the laptop heeding whatever the OS X energy saver setting is set to?

Power management will be controlled in part by the SMC but ultimately it's controlled by the OS. So you need to have Windows do all the right things. Have you installed the Boot Camp drivers? This may help with power manangement.

I'm showing my ignorance. I installed Bootcamp, then XP. Are the drivers separate downloads somewhere?

The process should go as follows…

1) Download and install Boot Camp (the current version is 1.3 so if you don't have it update now)
2) Launch the Boot Camp Assistant, burn a BC drivers CD and repartition your drive from BC
3) Reboot and install Windows
4) Install the BC drivers from the CD

PS You can burn a drivers CD at any time via the BC Assistant.

That looks like a familiar sequence. I think I did that when I got the MBP a couple of months ago. Do you think I need to reinstall everything?

I guess the bottom line question is: if you're running XP via Bootcamp, and your Power Settings are 15 min. to sleep on battery, and Never to sleep on AC, regardless of how your OS X Energy Saver is set, when you use the AC adapter your MPB should never sleep?

No, you shouldn't need to reinstall everything. At most you should need to update Boot Camp, burn a new drivers CD and install those drivers.

As for your scenario, you are correct, it should never sleep on AC under those conditions.
