Greetings:

A similar thing has happened to me on several occasions.  I have an HP 
Pavilion, model ze5470 US laptop, with a 2.66 GHz P4.  It happens when 
processor usage is high for an extended period, like when tarring a 
large file structure.  I noticed that this occurred after I upgraded the 
memory to 1 GB.  Perhaps the larger memory cards generate more heat.

Regards,

Gary
