memtest86 - yup. No problems revealed. heating - I instrumented the box with "logger `acpi -tB`" running on a 2-second loop. Temp was normal for the one freeze I captured.
bad caps - oh my! But as this is a laptop I will resist opening it up as long as possible. For various reasons I am semi-suspecting the wireless driver (rt2500). I am reminded of a very enjoyable evening spent in a certain lab with a 25 ft extension cord and a big box of random components... the end of the cord had been cut and stripped and alligator clips attached. I can confirm that the best pops come from capacitors. Rob Sherwood <[EMAIL PROTECTED]> wrote: > On Sun, Feb 18, 2007 at 01:00:16PM -0500, J.
