Yeah, I wasn't sure if stock PC-133 would do the trick, or if there
were a special laptop form factor.

First - (if it has one which most hsf on laptops do) removing the
thermal pad on the hsf and using some thermal compound and see if it
helps any.

I'll certainly check into that.

Second thing is check to see if the MB is cycling the fan. If not this
could be a bad fan, pad thermal probe or a needed bios update. Also
blow out any dust or debree that might be hindering cooling.

I actually don't remember hearing the fan, which was cause for concern;
but since I hadn't felt the thing be too warm, I thought maybe it was a
nonissue.

Third - Memory, if it is flaky, will cause weird errors and BSD's more
often than just a simple shut-down. I don't believe the memory is the
cause, but you might reseat the simms to check.

Can't hurt.

Fourth - All mobile Pentium III and Celeron mPGA, uPGA and MMC-2
processors have "speedstep" which is intel's speed throttle built into
the cpu for battery life. When the laptop is on battery power speedstep
runs the processor much slower, usually around 700mhz for a 1.13 and
decreased voltage, and thus causes less heat buildup from the processor
core. This would explain why you say the system works better with the
battery alone.

I actually haven't really tried it on battery alone. Maybe I mistated
something. The only configuration that had anything to do with the
battery specifically was its removal. I have an older Dell laptop that
won't even boot if the battery's in it, so I thought this might be
another case of a crappy laptop battery. I haven't run it on battery
alone, though.

Hope this helps!

I think it will. Thanks again.
