[Ti] PowerBook Sleep problems and Bluetooth mice

[Dennis Fazio]

As a piece of information discovered the hard way, be aware that there may be 
a problem with your PowerBook sleeping properly when you close the lid in the 
presence of an attached and active 3rd party Bluetooth mouse.

I have a couple of Kensington Pilotmouse Bluetooth wireless mice. After 
upgrading to Tiger, there were frequent times when after closing the lid, the 
machine would reawake (though only partially) within a few seconds, or if it 
stayed asleep, would not fully rewake (system active but screen black) upon 
reopening elsewhere.

After many steps in a structured song-and-dance sleep-wake troubleshooting 
session with an excellent Applecare fellow, who had seen this problem before, 
we isolated it to the mouse.

If you are having similar problems, there may be a compatibility problem 
between your mouse and PowerBook. The mouse is somehow maintaining a 
connection with the system, but it doesn't quite trigger the proper response 
in the system, so part of the PowerBook thinks it's awake and part of it 
(e.g. the graphics system) thinks it's still asleep.

Kensington said there may be a Tiger compatibility problem that they are 
investigating. Some of you may come across a similar problem with other brand 
mice. The Apple Bluetooth mouse seems to behave OK. In the meantime, the 
workaround is to pull one of the batteries out of the mouse before closing 
the PowerBook lid.
