If you are a Windows user wanting to use a Mac to run Windows - Don't do it
If you are a Windows user considering buying a Mac to use for running Windows, maybe occasionally booting in to Leopard, don't do it.
The Boot Camp drivers seem to be the source of the problem.
Shortly after installing Windows XP on the laptop, I noticed that the CPU utilization was hovering around 30% and the fan was spinning all the time. The laptop was loud and was HOT. I used SysInternals Process Explorer, and realized that the problem was with the power subsystem. After disabling the device "Microsoft ACPI-Compliant Control Method Battery" the CPU utilization dropped back down to nothing and the system usability returned. As a result of disabling the battery, the system has no power management and the battery lasts about 45 minutes.
The camera, remote control and special keyboard keys, don't work. They did briefly when I originally installed, but I had to re-install XP, and the drivers refuse to install and configure now. I get errors. I've tried to manually install / update the drivers from the Leopard DVD with no luck.
Firewire does not work correctly. I get numerous errors about delayed writes to my backup drive, E:. This is a bit worrisome. The drive works fine under Leopard and on other systems. The system slows to a crawl after the Delayed Write errors appear.
Basic things like doing a "print screen" of a dialog box, changing the speaker volume, ejecting a CD and changing the LCD backlight are impossible using the keyboard, since the drivers are not loading. Other features like the sudden motion sensor may or may not be working.
I'm a technical guy, and the last 2 months have been a huge headache trying to get the MBP running Windows XP as the primary OS. If I had things to do all over, I would have upgraded her to a regular laptop instead of the Mac. It's just been too painful.
