Power management on Macbook I am using Parallels for Mac with great success. There is only one very annoying thing which is power management or the complete lack of it. My battery lasts for 4 to 5 hours depending on the usage, but if I run a XP virtual machine, the battery never lasts for more than half of that, even if the vm window is minimized. The vm seems to keep the cpu busy all the time. Power management functions in the vm are not available. I am using 1922 at the moment, but I had same results with older versions. Any ideas? - Herzliche GrÃ¼ÃŸe aus westfÃ¤lisch Sibirien.
