Apple MacBook battery not detected when running Windows Vista under Bootcamp...

I have been running Windows Vista on my Apple MacBook for a while now. Installing it with Bootcamp was a breeze. Well done Apple - Microsoft could learn a lot from you in terms of making things simple and user-friendly. 

Oddly Vista works better on my Mac than it does on my newer Dell that was 'built for Vista'. (I could rant about my Dell all day but I'll spare you the rage - this time at least.) The only problem I've been having with Vista on the MacBook is that occasionally Vista stops detecting the battery. The 'phantom' battery still works as I can power the MacBook using just the battery but the taskbar icon in Vista tells me its not there. Not very useful if you are out and about and need to see how much battery you have remaining...

To start with I thought the problem was intermittent and I could remedy it by removing and putting back the battery... This is not actually the case. Once it happens it stays happened... until you reboot in Mac OS! Once you've run Mac OS and reboot into Windows Vista again the battery is back!

So in short - to fix the problem - boot the Mac OS then next time you boot Windows the battery detection works again.

Sorted! Now I just needs to figure out what makes the battery 'disapear' in the first place!
