Looks like Sleep, feels like Sleep... but it is NOT asleep.
 
(a Mac Support forum member) wrote 'by far most of the posts are pertaining to the emergency sleep mode caused by an overtemp signal' but I think we need to be careful as all we know is that the sleep mode is associated with the trackpad overtemp, with no causation proved. 

For instance, my Mac had a narcoleptic episode this morning shortly after booting, with hardly any temperature rise from cold. Also there have been Console references to Bluetooth, and this has not really been investigated, so I think more in terms of the pre-OSX extensions conflicts than simple one-agent causes. 

Another reason for my not accepting this temperature explanation is that I work with an extension monitor, and although the display disappears from my Powerbook screen it quite happily continues on the other screen. As I write this, my PB screen is black, & I am working on the other monitor.

I think that rather than get into a scrap about Windows v Mac, it would be more productive for everyone to, for instance, try a similar diagnostic procedure to compare results before tackling Apple, so we can present a coherent story. 

I am no techie, so I would be willing for someone with more knowledge than I to draw up a simple set of tests so that we can eliminate some things, & maybe point up others.... James
