标题:

Random sleep (and will not wake without complete power removal)

文本:

My PB started sleeping involuntarily after being on for a while.  From the temperatures shown with a utility program it seems usually to be showing major overheat beforehand, but there is some irregularity.

I have to pull the battery and wait a while for it to be restartable.

It also comes back up in verbose logging mode, which shows a line about a temperature problem, also.

The fan(s) is(are) doing strange things, like running with great noise as it starts up from this hard sleep.

I took it to the Genius bar, and after running tests, their advice was new logic board.  I have been falling back on my desktop and procrastinating/not sending it in.

Then I read on the Yahoo list where a Macbook user had a similar problem which she traced to a fan clogged with debris.  We have several cats inside and their hair is certainly a culprit elsewhere.

I have 2 questions:  Does this sound like a possible solution and is it possible to remove or at least clean the fan without the mega-disassembly require per the guide here to get at it?

Many thanks!
