I had a laptop with similar symptom when I was compiling stuff. I took it apart, cleaned it and thought that maybe these log messages were normal under stress. The CPU eventually fried and only then I took a real close look and the heatsink had a very tiny little hole where the fluid escaped, but it was not at all apparent at first sight. These liquid (or gel?) filled heatsinks are basically useless if the liquid escapes or evaporates so it will usually only show when you are using the CPU a lot. -- Alejandro Imass > Thanks > > -- > Anton Shterenlikht > Room 2.6, Queen's Building > Mech Eng Dept > Bristol University > University Walk, Bristol BS8 1TR, UK > Tel: +44 (0)117 331 5944 > Fax: +44 (0)117 929 4423 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
