My MacBook Pro 17" (4 days old) does not see the mains adaptor plugged in on the task bar, I noticed this when I decided to run the Performance Information and Tools feature in Vista, it stated the task could not be run due to being on battery power, this is going to be a nightmare if you have got to remember to unplug and replug the adapter everytime you boot up, all updates available (I think) have been applied to both MAC OSX and Vista, any ideas or help most appreaciated. It must be a Boot Camp issue as the adaptor works fine in MAC OSX, in additon it's fine in Vista using Virtual PC2007 with XP Pro..... Thanks in advance for any help or suggestions - It's driving me crazy :-/ Error Message Below From Microsoft Problem caused by Advanced Configuration and Power Interface This problem was caused by a compatibility issue between Windows Vista and Advanced Configuration and Power Interface.
